Summary of synthesis methods for silicon carbide ceramics
Silicon carbide ceramics have excellent characteristics such as high mechanical strength, high temperature resistance, strong oxidation resistance, good thermal stability, high thermal conductivity, good wear resistance, good chemical corrosion resistance, high hardness, and good thermal shock resistance.
RBSIC Silicon carbide has the best oxidation resistance among all non oxide ceramics. Silicon carbide ceramics not only play an important role in the field of high-tech, but also have broad markets in popular fields such as metallurgy, machinery, energy, and building materials and chemical engineering.
With the continuous development of high-tech, the demand for Reaction bonded silicon carbide ceramics is also increasing. Various products with different levels and performance are required.
As early as the 1950s, Popper first proposed the preparation of Reaction sintered silicon carbide ceramic. RBSIC Silicon carbide ceramic basic principle is that reactive liquid silicon or silicon alloy infiltrates into porous ceramic billets containing carbon under capillary force, and reacts with the carbon to generate silicon carbide. The newly generated silicon carbide in situ combines with the existing silicon carbide particles in the billets to fill the remaining pores in the billets, completing the densification process.
