Third grade silicon carbide

Product Name: Third grade silicon carbide   Introduction： Silicon carbide has various appearances: due to the presence of impurities, common ones include black silicon carbide, green silicon carbide, yellow or blue. Silicon carbide crystal has various structures, ranging from plate-like, columnar, or cubic silicon carbide, to macroscopic irregular abrasive particles such as some cubic forms of primitive silicon carbide, and to circular chips in high-tech fields.The core of  silicon carbide element of third grade SiC is still silicon (Si)  and carbon (C) , existing in the form of SiC  compounds. The main content of SiC is usually about 70%, which generally refers to the fluctuation of SiC content between 60% and 85%, with the remainder being impurities. The impurity content is higher than that of the first and second stages. Common impurity elements include free silicon, free carbon, iron, aluminum, etc.   Usage: Silicon carbide composite materials have a…
