 	<li><a href="https://www.xinliabrasive.com/White-Fused-Alumina.html">White corundum</a> and silicon carbide are materials with similar physical and chemical properties. For customers who want to buy white corundum, it is important to know the difference between white steel and silicon carbide.</li>
</ul>
&nbsp;
<ul>
 	<li>White corundum is a product produced from industrial alumina powder. With a Mohs hardness of 9 and a micro-hardness of 2200 kg/mm2, it is second only to diamond. The main components are Al2O3, Fe2O3, SiO2, MgO2, etc. The presence of iron in white corundum can lead to iron spots in ceramic abrasives and refractory products, which will not only make the appearance of the product unattractive, but also cause the degradation of the use performance. Therefore, the iron content in white corundum should be well controlled.</li>
</ul>

<ul>
 	<li>White corundum is suitable for solid tissue and coated abrasives, but its hardness and toughness are not as good as silicon carbide, and it is not as effective as silicon carbide for sandblasting. According to the content of alumina powder can be divided into primary and secondary, using electrofusion method of crystallization, high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, stable performance in the thermal state. Hardness is slightly higher than brown corundum, slightly lower toughness, strong grinding ability, small calorific value and high efficiency.</li>

 	<li><a href="https://www.xinliabrasive.com/Green-Silicon-Carbide-Powder.html">Silicon carbide (SiC)</a>, on the other hand, is made by high-temperature smelting in electric furnaces, such as quartz sand, petroleum coke (or coal coke) and wood chips (salt needs to be added in the production of green silicon carbide) ). Silicon carbide is also found in nature as a rare mineral, moissanite. Silicon carbide is also known as carbon silica. Among the C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide is the most widely used and economical raw material, which can be called gold steel sand or refractory sand. The main characteristics are good toughness, good thermal conductivity, high hardness, few impurities, relatively pure, but the disadvantage is fragile; suitable for surface treatment, is a high-quality sandblasting machine consumables;</li>
