How to disperse the Silicon carbide whisker:
1. After pre-dispersion, water and ethanol are used as mechanical media for dispersion, and then mixed with the matrix material before using silicon carbide whiskers.
2. Generally, the addition amount of ceramics is 1-10%. The greater the true density of the matrix material, the less the addition amount of silicon carbide whiskers; the addition amount of organic materials is 0.5-3%.
3. If the silicon carbide whiskers are mixed with ceramic materials, mechanical stirring or wet grinding is recommended. The silicon carbide whiskers can be reduced under high-intensity mixing conditions to break the odds.
4. For semiconductor and catalysis testing, the customer again recommends pickling to remove sorbate to improve research activity and achieve the best results.
5. Under aerobic conditions, the whisker heating temperature should not exceed 700°C.
