silicon nitride (Si₃N₄) ceramic is widely used for its excellent heat resistance, oxidation resistance, and mechanical strength. However, recent studies indicate that under extreme high temperatures (≥1300°C), Si₃N₄ may react with carbon, gradually transforming into silicon carbide (SiC) ceramic while releasing nitrogen gas (N₂).

Compares zirconia ceramic and alumina ceramic, highlighting their differences in hardness, toughness, wear resistance, chemical stability, and thermal properties. It also explores their key applications in machinery, electronics, biomedical, and chemical industries, helping readers choose the right Aluminum Oxide or Zirconium Oxide ceramic for specific needs.

​In high-temperature industrial applications, alumina ceramic tubes have proven to be a superior choice due to their exceptional thermal resistance, mechanical strength, and chemical stability. Whether used in high-temperature furnaces, steel smelting, metal casting, or glass manufacturing, alumina ceramic tubes ensure long-term durability and reliable performance.

In plasma etching equipment, essential ceramic components include ceramic chambers, SiC focus rings, SiC electrostatic chucks, Alumina Ceramic nozzles, gas dispersion plates, and other structural elements.

Whether you need uniform heating, efficient pouring, or precise material handling, the right crucible can greatly impact your results.Selecting the right crucible involves understanding your specific process requirements.

PBN (Pyrolytic Boron Nitride) crucibles are valued for their purity, thermal shock resistance, and durability. They prevent material contamination, crucial in impurity-sensitive processes, and endure rapid temperature changes without cracking. Their electrical insulation suits non-conductive applications, and their diverse shapes cater to specific needs.

At the start of 2025, KYOCERA Fineceramics Europe GmbH announced the establishment of a new facility in Erfurt, Germany, enhancing its existing multi-wire saw technology capabilities and production infrastructure.

On December 23, media outlets such as The Economic Times reported that Silectric Semiconductor, a subsidiary of Zoho Corporation, will establish Karnataka's first semiconductor manufacturing plant in India, dedicated to integrated production of silicon carbide.

Recently, Kyocera announced the development of a new silicon nitride ceramic material for functional testing of next-generation microchips. This new material boasts enhanced thermal expansion properties and flexural strength, enabling the production of thin silicon nitride plates with extremely narrow spacing between contact probes, which is critical for testing next-generation microchips.

Recently, KYOCERA held a groundbreaking ceremony for its fine ceramics factory for medical implants, located in Waiblingen, near Stuttgart, Germany. This facility will specialize in manufacturing high-quality ceramic heads used in hip prostheses and other implant applications. The project is expected to be completed by September next year.

Recently, Alpha HPA, an Australian company, has commenced construction on the second phase of the world’s largest single-location ultra-high-purity alumina refinery.

According to data from QY Research, the global market size for silicon carbide (SiC) ceramics used in semiconductors was $1.111 billion in 2023. Driven by the rigid demand from downstream industries, it is projected that the silicon carbide ceramics market will grow to $1.578 billion by 2030, with a compound annual growth rate (CAGR) of 5.09% from 2024 to 2030.
