Black silicon carbide sand is an artificial abrasive grit for coated abrasives. Sanding fiber disc with SiC abrasive is suitble for stainless steel deburring, alloy and wood surface cleaning,etc. But not all black silicon carbide is qualified for this application. High cleanness and low conductivity of Black silicon carbide P24-P180 is very important for electrostatic sand-planting process.
Green silicon carbide is an excellent abrasive powder in industry. Usually used for grinding titanium alloys, quartz glass, and stone. Green silicon carbide also plays an important role in nail tools and body care. Green SiC powder F60 F100 F150 are suitable for sand caps making.
Black silicon carbide grit F16/F24 is an excellent wear resistant material for abrasion usage. In the construction industry, the black SiC grit works well for anti-slip flooring. For the cost of black silicon carbide is higher than other flooring aggregate. It mostly for workshop, laboratory, airport, hotel, public indoor anti-slip floor rather than outdoor pavement and road. It can work as aggrgate in anti-slip floor sheet and industrial conveyor belt as well.
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.
