Analysis of Beta SiC whisker

SiC silicon carbide whiskers are key new materials of high-tech. They are reinforced tougheners for advanced composites such as metal-based, ceramic-based and high-polymer bases. They are used in ceramic-based, metal-based and resin-based composites. It has been widely used in ceramic tools, space shuttles, automotive parts, chemicals, machinery and energy production.

The main application areas of SiC whiskers are toughening ceramic tools. The United States has successfully developed "SiC whisker and nano-composite coating" for wear-resistant, corrosion-resistant and high-temperature coating. The market demand for SiC whiskers will increase sharply, and the market prospect is very broad.
Silicon carbide whiskers have excellent mechanical properties, heat resistance, durable corrosion resistance and high temperature oxidation resistance. The new product has good compatibility with matrix materials and has become a major enhancement of various high performance composite materials in recent years. One of the toughening agents. Widely used as a composite material for metals, plastics and ceramics. Silicon carbide whisker reinforced composite materials can be developed for use in aerospace, military, mining, chemical, automotive, sports equipment, cutting tools, nozzles, high temperature parts and other fields. Whisker-reinforced silicon nitride ceramic matrix composites have excellent physical and mechanical properties, and can be widely used in various wear-resistant, high-temperature, corrosion-resistant and anti-shock applications, in addition to engine parts, and have broad prospects. . There are great market demands in cutting tools, stone saws, textile cutters, sand blasting nozzles, high temperature extrusion dies, sealing rings and armor.
The main components of the structural ceramics market in North America are cutting tools, wear parts, heat engine parts and aerospace products. Approximately 37% of structural ceramic parts are made from ceramic matrix composites. The rest is a single ceramic product. Ceramic matrix composites are mainly used in the production of cutting tools, wear parts, inserts and products for the aerospace industry. For cutting tools, most of the products (about 41%) made of matrix composite ceramic matrix composites made of TiC, reinforced Si3N4 and Al2O3, and SiC whisker-reinforced Al2O3 are wear-resistant products, some types. Ceramic composites are also used in radar, engine and aircraft gas turbines. 17% of structural ceramics are used on ceramic tools. Including Al2O3, Al2O3/TiC, SiC whisker reinforced Al2O3, Si3N4 and Sialon ceramics. The development speed of the ceramic tool market is benefited from the acceleration of the industrialization process. The SiC whisker enhancement of the price of Al2O3 and Si3N4 tools also makes ceramic tools more competitive in the market.
