Focusing on key powder preparation, jointly exploring new opportunities in filtration and separation for advanced materials.

From November 3 to 4, 2026, an industry forum themed “Innovative Development in the Preparation of Key Powders and Pastes for MLCCs” was held in Dongguan, Guangdong.

This forum brought together companies across the MLCC industry chain, research institutes, and industry experts to engage in in-depth discussions on the preparation processes, technological innovations, and industrial applications of key materials such as ceramic powders, metal electrode materials, and functional pastes.

Xiamen Xiadis Filtration Materials Technology Co., Ltd., a leading company in filtration and separation materials and nanomaterial powder filtration, was invited to attend this major industry event to discuss, together with upstream and downstream enterprises and industry experts, innovative applications of advanced powder material preparation and high-precision solid–liquid separation technologies.

I. Focusing on Industrial Upgrading and Jointly Exploring New Directions in the Development of Key MLCC Materials

As the world’s largest producer and consumer of MLCCs, China accounted for nearly 52% of global production in 2025, with consumption reaching approximately 580 billion units. Driven by technological breakthroughs among domestic firms in medium-to-high voltage and high-capacitance specifications, the localization process is accelerating. By 2030, China’s MLCC market is projected to reach US$32 billion, with an average annual growth rate of about 7.1% from 2026 to 2030—outpacing the global average. However, high-end segments still exhibit roughly 30% import dependence, particularly in automotive-grade and RF‑type MLCCs.

As industries such as AI computing servers, new energy vehicles, 5G communications, and consumer electronics continue to grow, the MLCC (multilayer ceramic capacitor) market is placing increasingly stringent demands on the performance, quality, and stability of critical materials.

In the manufacturing cost of MLCCs, raw materials account for approximately 50–60%, with ceramic powder and nickel powder representing the two most critical bottlenecks.

1. Ceramic powder (BaTiO₃)

Barium titanate (BaTiO₃) is the core dielectric material in MLCCs, determining all key electrical parameters such as capacitance, temperature characteristics, and reliability. The grain size, purity, and particle-size distribution of BaTiO₃ directly affect the layer thickness and capacitance density of MLCCs—the thinner the layers, the finer the powder required (below 100 nm), imposing extremely stringent demands on the synthesis process.

2. Nickel powder (internal electrode)

Modern MLCCs commonly use the base metal (BME) process, replacing palladium/silver with nickel for the internal electrodes. Nickel powder must have a purity of ≥99.9%, and its particle size typically ranges from 100 to 300 nm. Global nickel powder supply is almost monopolized by two Japanese companies: Sumitomo Metal Mining (the world’s largest) and Toho Titanium (the second largest). China lacks the capacity for stable mass production of high-purity, ultrafine nickel powder that meets MLCC requirements, making this a major raw-material bottleneck for mainland China’s MLCC industry.

3. Internal Electrode Paste and Terminal Electrode Materials

The internal electrode paste (nickel powder plus organic binder) is predominantly supplied by Japanese manufacturers; the terminal electrodes use copper paste with a nickel–tin plating. Domestic production of copper paste is well established, and domestic equipment for nickel and tin plating processes has become quite mature.

4. Cost Structure Analysis Across All Stages of the Industry Chain

To understand the value flow within the MLCC industry chain, one must start with the cost structure. Raw material costs account for approximately 50–60% of total expenses, with ceramic powder making up about 25–35% of material costs, nickel powder around 15–20%, internal electrode paste roughly 10–15%, end‑electrode copper paste and tin‑plating materials about 5–10%, and PET release film approximately 3–5%. Thus, powder and nickel powder together comprise roughly 40–55% of material costs, making them the highest‑priority targets for achieving self‑sufficiency in raw materials.

In particular, in the field of high-end MLCC manufacturing, the preparation processes for ceramic dielectric powders, metal electrode powders, and their associated slurries impose stringent requirements on material purity, particle size, dispersion uniformity, and production stability.

From powder preparation and grinding/dispersion to slurry processing, and on to subsequent solid–liquid separation and drying, every stage of production affects material quality and manufacturing efficiency.

This forum focused on ceramic powders such as barium titanate, magnesium titanate, and strontium titanate, as well as metallic electrode materials including nickel, copper, silver, and palladium. It brought together industry expertise to share cutting-edge research findings and industrialization practices, establishing a platform for upstream and downstream companies to engage in technical exchange, resource matching, and collaborative innovation.

II. Deepening Expertise in Filtration and Separation to Empower Advanced Powder Material Manufacturing

As a national high-tech enterprise integrating the R&D, manufacturing, and sales of filtration materials with advanced filtration technology, Xiamen Xiadis has long been dedicated to industrial filtration and solid–liquid separation, continuously advancing the innovative application of filtration materials and technologies.

In the manufacturing of advanced powder materials, the feedstocks often exhibit characteristics such as fine particle size, stringent purity requirements, wide variations in slurry viscosity, and complex filtration conditions. Ensuring product quality while achieving efficient solid–liquid separation, minimizing material loss, and enhancing production efficiency are key challenges that relevant companies focus on during the production process.

III. Driven by technological innovation, explore new applications for high-precision filtration

In response to the ever‑rising filtration demands of the new materials industry, Xadidas continues to ramp up its R&D investment and actively explores the limits of applying fine and high‑precision filtration technologies.

The company’s independently developed advanced filtration technology addresses common issues in conventional filtration—such as material carryover and cloth clogging—when processing ultrafine powders, and explores highly efficient solid–liquid separation solutions for nanoparticles and micrometer-sized particles.

It employs a purely physical filtration process, requiring no chemicals or additives, and can integrate filtration, washing, and dewatering steps according to the material’s characteristics.

In fields such as ultrafine powders, precious metal powders, and high-value-added materials, effectively capturing fine particles, minimizing material loss, and ensuring product purity are key priorities driving ongoing innovation in filtration technology.

Participating in this MLCC Key Powder/Slurry Preparation and Innovation Development Forum also provided Xiadis with an excellent opportunity to gain a deeper understanding of the filtration needs of the advanced electronic materials industry and to expand collaborative applications in the new materials sector.

IV. Strengthening Industry Chain Exchanges to Jointly Explore New Opportunities for Collaborative Development

This forum brought together numerous MLCC manufacturers, key powder material suppliers, production equipment companies, and research institutions, establishing a high-quality platform for exchange across the industry chain.

During the conference, Xiamen Xiadiyas engaged with industry companies and professionals from various sectors, discussing topics such as powder material production processes, filtration and separation technologies, product application requirements, and future collaboration opportunities.
