Tech Ceramic Pillars NSiC High Temperature Sintering

Silicon nitride bonded silicon carbide pillars, also known as horselegs, are mainly used as structural supports and wear-resistant components in high-temperature environments.
High strength and toughness: Silicon nitride combined with silicon carbide, NSiC pillars combine the advantages of both silicon nitride and silicon carbide, greatly improving the fracture toughness of the material.
Structural support in high-temperature environments: NSiC pillars, with their high temperature resistance and hardness, can maintain structural stability in high-temperature environments and are commonly used in high-temperature sintering furnaces and other high-temperature scenarios. NSiC pillars have a long service life.
Chemical stability: NSiC pillars have strong corrosion resistance and almost no reaction with acid or alkali at room temperature. The excellent antioxidant and corrosion resistance of NSiC pillars give it an outstanding service life.
Excellent thermal shock resistance: After the combination of silicon nitride and silicon carbide increases density, the bending strength is improved, which can extend the service life and reduce thermal stress problems during equipment operation. The NSiC pillar prevents the material from cracking or peeling instantly. This is the key reason why NSiC pillars are widely used in fast cooling and heating environments.

PRODUCT DETAIL



The combination of silicon carbide pillar and plates with a firing frame is a very classic and important kiln design scheme in industrial kilns, especially in the fields of ceramics, lithium battery materials, electronic component sintering, etc. This structure is commonly referred to as a "shed slab structure" or a "pillar shed slab system".
The design of the firing frame with silicon carbide pillars and shed boards is an efficient, reliable, and flexible solution for kilns. When choosing, NSiC pillar is strongly recommended to use kiln furniture , as NSiC pillar provides the best combination of strength, toughness, and thermal shock resistance, ensuring safe production, stable operation, and extended service life.
