Silicon carbide is a typical covalent bond compound. It is an artificial material that doesn’t exist in nature. Silicon carbide materials have many excellent properties, such as abrasive resistance, high-temperature resistance, corrosion resistance, high thermal conductivity, high chemical stability, wide band gap, and high electron mobility.
A soft bulletproof vest can only protect against low-speed bullets. For high-speed bullets or some steel core bullets fired from rifles, it can get bulletproof by inserting hard shields at key positions based on soft bulletproof vests. At present, hard guard armor made from Silicon carbide composite ceramic plates can meet the requirements of proper weight, performance, and price. Black silicon carbide grain and powder can be raw materials to produce bulletproof armor.
Green silicon carbide blasting media is an excellent abrasive medium for titanium alloy or titanium products. Titanium alloy processing often requires grinding, polishing, sandblasting, and other processes. General grinding media such as garnet and alumina are not suitable for titanium alloy materials, but green silicon carbide abrasive with stronger grinding force performs well with this application.
Black silicon carbide is an artificial abrasive material. It can work fantastic for sandblasting, abrasive tools, anti-slip, and heat resistance fields. However, the quality and technical indexes are different because of the different production technologies. Basically, the 98% black silicon carbide and 99% black silicon carbide are both A-grade SiC.
Silicon carbide is an excellent refractory material for many thermal insulation fields. A grade black silicon carbide as the highest quality level silicon carbide, the purity of SiC is min 98%. High purity black silicon carbide is an important additive for anti-corrosion, thermal insulation and wear resistance coating and ceramics. Black silicon carbide JIS320# works as wear resistance media on the production of welding rod.
Green silicon carbide grain F30 is a relatively coarse grit for sandblasting. It is suitable for making GC abrasive discs and abrasive wheels. For blasting, F30 green silicon carbide is a normal grit for surface treatment on ceramic, marble, and non-ferrous metals such as copper, titanium alloy, and tungsten carbide.
