Advanced NSiC kiln furniture

Advanced NSiC kiln furniture, an ideal choice for modern industry, is providing solid support for efficient production across various sectors with its outstanding performance.

In terms of the production process, the slip casting process and the unique two times firing technology complement each other to create high - quality kiln furniture. First, raw materials such as silicon carbide and silicon nitride are finely ground to form a uniform slurry. The slip casting process is then used to precisely control the density and structure of the green body, ensuring product consistency. Subsequently, the crucial two times firing process begins: In the first firing, a vacuum furnace is used for high - temperature sintering, and nitrogen is introduced for nitridation during the high - temperature process. This allows silicon nitride to fully penetrate the silicon carbide framework, strengthening the bonding force between the two phases and improving the overall strength and density of the green body.

In the second firing, the kiln furniture is sintered in an oxidation furnace. The high - temperature oxidation atmosphere promotes the formation of a dense oxide film on the surface of the kiln furniture. This oxide film not only enhances the anti - oxidation performance of the kiln furniture but also effectively resists corrosive media, further extending its service life. Through this process, the kiln furniture is extremely hard, with a Mohs hardness of up to 9, second only to diamond. In a high - temperature environment of 1200 - 1400°C, its strength and hardness are almost the same as at room temperature. Meanwhile, it has a low coefficient of thermal expansion and high thermal conductivity, making it less prone to thermal stress caused by temperature changes. It has excellent thermal shock stability and can withstand extreme cold and heat.

In practical applications, advanced NSiC kiln furniture fully demonstrates its advantages. In the ceramic industry, it can effectively reduce the mass ratio of kiln furniture to products, save energy, and improve product quality and qualification rates. In the fields of electrical porcelain and electronic ceramics, its characteristics of high strength at high temperatures and long service life perfectly meet production requirements. In addition, it is widely used in industries such as steel, non - ferrous metals, chemical engineering, and building materials.

Choosing advanced NSiC kiln furniture means choosing efficiency, stability, and durability.
