The front windshield and outer glass of a car usually require cleaner with abrasive particles to remove oil film. Rainstains, water stains, plant and animal oil stains, bird droppings and other stains are difficult to remove with ordinary cleaner. Grinding type glass oil film cleaner can remove the staines quickly and efficiently.  Functional abrasive particles is necessary for glass oil film remover to improve the removal efficiency. Silicon carbide powder and cerium oxide powder are commonly used materials.

88-90% Black SiC is mostly used for refractory and metallurgy field. In the steel making process, black SiC is a good dioxidation agent. Although 1-10mm and 0-10mm is similar in particle size, the price varies somehow. There will be retain 0-1mm for the seiving of SiC 1-10mm. Moreover, the powder 0-1mm is not so popular. So there is more production cost for 1-10mm black SiC fractions.  Thus, the price of 88-90% black SiC 1-10mm is higher than that of 0-10mm.

When considering grinding hard materials, green silicon carbide must be on the list of alternative materials. Aluminum nitride ceramic is a new type of ceramic with high thermal conductivity, heat shock resistance, mechanical strength, and bending strength. Its hardness can reach 12Gpa, and the Mohs hardness is 7-8. Green silicon carbide is typically suitable for grinding materials such as jade, crystal, borosilicate glass, silicon wafers, optical glass, etc., with a Mohs hardness of 6.5-7. It shows that using green SiC 5micron for polishing aluminum nitride ceramic substrates and ceramic components can also achieve efficient grinding.

In the field of sapphire wafer polishing, the commonly used grinding material is boron carbide. However, the price of boron carbide is high, and for situations that require rapid removal, GC powder (Green silicon carbide powder) can also achieve the desired grinding effect.

Silicon carbide black grit for grinding   There are many types of abrasive grains including corundum and silicon carbide. And the principles of choose proper one are directly related to the physical and mechanical properties of the processed material. Generally speaking, when grinding workpiece materials with high tensile strength, it is advisable to choose aluminum
