Green silicon carbide powder raw material selection

Green SiC is a high-tech refractory , has been in use in various industries , more and more , and it has many excellent performance in a high-performance products , silicon carbide, green silicon carbide and black can be divided into carbonization silicon , here to introduce you to a green silicon carbide powder of raw material selection , I hope for your help .
Green silicon carbide is quartz sand and coke for raw materials as a good thermal conductivity , high hardness of man-made materials . Silicon carbide powder is widely used in refractory, wear-resistant flooring , ceramic foam , specialty coatings, corrosion-resistant paint, flow separation and environmental protection industries , green silicon carbide even at high temperatures also have high strength , elastic modulus at the temperature reaches its 1600 ℃ , began attenuation. At a temperature of 2815 ° C begin to separate , but it does not melt at atmospheric pressure . Green silicon carbide grain of sand can quartz sand and coke as raw materials, manufacture green silicon carbide powder with a grain of sand , and you can choose as raw materials of sand . Green silicon carbide powder raw materials first look at the color , the second depends on the hardness , the third depends on the content .
