Silicon carbide ceramics (SiC ceramic) offer a unique combination of high hardness, excellent high-temperature resistance, superior wear resistance, and outstanding corrosion resistance, making them an essential material in refractory applications, mechanical seals, heat exchangers, and high-power electronic components. However, their brittleness, poor thermal shock resistance, and high production costs pose certain limitations. Despite these challenges, high-hardness silicon carbide remains a key material in industries requiring durability, strength, and thermal efficiency, proving its significance in modern engineering and advanced manufacturing.

Silicon nitride ceramic (Si3N4) offers a wide range of advantages such as high hardness, excellent thermal stability, corrosion resistance, and low density, making it suitable for demanding applications across various industries. However, its brittleness, machining challenges, and poor electrical conductivity are factors to consider when choosing it for specific applications. Despite these drawbacks, the material's unique properties continue to drive its adoption in fields like aerospace, automotive, and electronics.

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.

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.

Based on the phase transformation toughening effect of metastable tetragonal zirconia under stress induction, zirconia phase transformation toughening ceramics mainly include Tetragonal Zirconia Polycrystalline (TZP), Partially Stabilized Zirconia (PSZ), and Zirconia Toughened Ceramics (ZTC).

In modern industry, material selection greatly affects equipment performance and lifespan. In the foundry industry, riser tubes, key to low-pressure die-casting machines, significantly influence casting quality and efficiency. Silicon nitride has emerged as the preferred material for riser tubes due to its excellent properties.
