Pressureless sintering and reaction sintering are two processes for sintering silicon carbide products. Due to their different firing processes, the performance of Good Quality Si3n4 Ceramic Thread Bush Spacer Custom their products is also different. The main highlights are the technical parameters of pressureless sintered silicon carbide materials and the technology of reaction sintered silicon carbide materials. parameter.
1 The firing process is different
Reaction sintering is to make free silicon penetrate into silicon carbide at a lower temperature. The pressureless sintering is a silicon carbide product formed by natural shrinkage at 2100 degrees.
2 The technical parameters of sintered products are different
The reaction volume density, hardness, compressive strength, etc. are different from the technical parameters of pressureless silicon carbide products.
3 Product performance is different
Reaction sintered products and Good Quality Si3n4 Ceramic Thread Bush Spacer Custom pressureless products have different use times under different pH and temperature conditions.
Pressureless sintered products have smoother surface, higher density, and higher strength than reaction sintering. According to the characteristics of pressureless, such as seals, the surface requirements are strict. Pressureless sintered products have replaced reaction. Sintered products. Reaction sintered silicon carbide has high strength, high hardness, high wear resistance, high temperature resistance, corrosion resistance, high oxidation resistance, good thermal shock resistance, good thermal conductivity, rapid cold and rapid heat resistance and high temperature Good Quality Si3n4 Ceramic Thread Bush Spacer Custom creep resistance. Performance and main features. It can be made into beams, rollers, quench air ducts, thermocouple protection tubes, temperature measuring tubes, flame nozzles, wear-resistant parts, corrosion-resistant parts, seals and special-shaped structural parts. Reaction sintering silicon carbide production process is relatively simpler than pressureless du sintering. Generally, reaction sintering can be used to meet the requirements of ordinary industrial silicon carbide products. No pressureless sintering is required.
What is the difference between reaction sintering and pressureless sintering silicon carbide ceramic?
