Cubic Silicon Carbide Whiskers is a high -strength beard -shaped (one -dimensional) monolithic, which has many excellent mechanical properties such as high -strength and high models. It is widely used in metal-based and ceramic-based composite materials. It is mainly used in high -temperature components in the field of ceramic tools, the field of space, bearing, large mud pumps, etc.

Physical characteristics: It is a cubic crystal type, which is the same crystal type as diamond.

Chemical characteristics: anti-wear, high temperature resistance, especially heat shock resistance, corrosion resistance, radiation resistance.

Application: high-end ceramic bearing, mold, high-voltage firing, high temperature resistance, etc.

Silicon carbide has a diamond crystal structure. This is due to the carbon and silicon elements that form SiCs. They belong to the SP element of IVA in the element cycle table. When these elements form crystals Large stability SP3 is arranged, there is a solid covalent key, the common price characteristics and high strength of the key, determining that silicon carbide has certain energy and mechanical strength. SIC’s MOBS hardness reached 9.5, second only to diamond. Cubic SiC whiskers have higher hardness, modulus, tensile strength and high temperature resistance than other whiskers material.

SiC whiskers be evenly distributed in the dense body material as the second phase particles, which can match the body well. After the high temperature is formed, because the thermal expansion coefficient of the crystal and the body material is different, the crystal and the body material interface interface After the surplus stress is generated, after the composite material is slightly cracks, the stress of the crack end extends to the crystal and matrix interface. Absorbing external stress. In this way, the SiC whiskers can prevent the further expansion of micro -cracks by ”bridge couplet”, “crack deflection”, “crystal pull out effects” and “broken crystal effects”, thereby enhancing and reinforcing the body of the body. The composite material has high toughness and mechanical properties. Because SIC crystals must have good stability at high temperatures, its enhanced and tougher composite materials can still maintain good mechanical properties when 1000 ° C above 1000 ° C.

Cubic Silicon Carbide Whiskers can be used as enhanced materail in plastic matrix, metal matrix or ceramic substrate to enhance and reinforce. The high thermal guidance, high insulation of SIC materials, substrates for large -scale integrated circuits in the electronics industry and Packaged materials. As an information optical material, it has high application value in the fields of TV display, modern communication, and network.

Carbonic silicon carbide whiskers are very excellent enhancement material for metallic, ceramic, and polymer polymer base composite.
