Bloque cerámico de carburo de silicio

Bloque cerámico de carburo de silicio is a high-performance advanced ceramic material prepared mainly from high-purity silicon carbide (SiC) through advanced sintering processes such as pressureless sintering and reaction sintering. It perfectly inherits the inherent advantages of silicon carbide materials and is made into block, plate or irregular structural parts of various specifications and sizes through precision machining, making it a key material for solving extreme working conditions challenges in modern industry.

Características principales y problemas resueltos:
Silicon carbide ceramic blocks are not ordinary materials, and their design aims to solve the pain points of insufficient performance of traditional materials (such as metals, ordinary ceramics, graphite, etc.) in harsh environments:

1. Ultimate wear resistance, solving the problem of rapid equipment wear and tear
   Problem: In industries such as mining, power, metallurgy, etc., equipment wear and tear in the material conveying and crushing processes is extremely severe, resulting in short lifespan of metal components, frequent replacement, and high maintenance costs due to downtime.
   Solution: Silicon carbide ceramic blocks have extremely high hardness, second only to diamond and cubic boron nitride, and their wear resistance is tens of times that of high chromium cast iron. Using it to make lining plates, nozzles, liners, etc. can greatly extend the service life of equipment, reduce downtime, and lower overall maintenance costs.
2. Excellent high temperature resistance and high thermal conductivity, solving thermal management problems
   Problem: In fields such as high-temperature furnaces and semiconductor heat treatment, traditional refractory materials have good thermal insulation but poor thermal conductivity, which affects heating efficiency; And metals are prone to softening and oxidation at high temperatures.
   Solution: Silicon carbide ceramic blocks can work stably for a long time at high temperatures of 1600 ° C, and their high-temperature strength does not decrease but instead increases. At the same time, it has excellent thermal conductivity and is an ideal material for heat exchangers and kiln furniture supports (rollers, plates). It can withstand high temperatures while achieving efficient and uniform heat transfer, improving energy utilization and product quality.
3. Outstanding chemical corrosion resistance, solving the problem of corrosion in harsh environments
   Problem: In industries such as chemical, environmental protection, and papermaking, corrosive media such as strong acids, strong alkalis, and molten salts can cause serious corrosion to equipment, posing safety hazards and pollution risks.
   Solution: Silicon carbide ceramic blocks have extremely strong resistance to most acids, bases, and salts, and have extremely high chemical stability. Using it to make sealing rings, valves, pump components, and chemical reactor liners can effectively resist chemical corrosion, ensure long-term reliable operation of equipment, and protect the purity of the production process.
4. High hardness and stability, solving deformation and vibration problems in precision machining
   Problem: In precision machinery, optics, and semiconductor manufacturing, workbenches and structural components require extremely high rigidity and dimensional stability, and any small deformation or vibration can affect machining accuracy.
   Solution: Silicon carbide ceramic blocks have a high specific stiffness (ratio of elastic modulus to density), which is much higher than that of cast iron and aluminum alloys, and has an extremely low coefficient of thermal expansion. As a measurement platform, optical mirror holder, and robot arm component, it can effectively suppress deformation and vibration, ensuring extremely high dimensional accuracy and stability under temperature and load changes.
