Refractory Silicon Carbide advantages

Refractory silicon carbide is a synthetic refractory material based on SiC substance (CAS:409-21-2). It is made from silica granules and carbon material in a huge resistance electric furnace at about 2800 degrees.  Refractory Silicon carbide chunks, nubbles, and powder always work as refractory lining, furnace castale, and mortar. Silicon carbide is a better refractory aggregate and castable than aluminum oxide-based refractories for its extraordinary advantages as follows:

Black Silicon Carbide F20 F24 F30 F54 F70 anti-skid floor aggregate

Black silicon carbide (Carborundum) is a good filler as an anti-skid aggregate in flooring. It can improve the anti-skid performance and service life. Meanwhile, it can reduce maintenance costs after installation. At present, the main materials added to wear-resistant flooring include quartz sand, garnet, aluminum oxide, silicon carbide, and other materials.  The cost of Silicon carbide is the highest. However, it’s the most workable one with good wear resistance, corrosion resistance, and durability. Black silicon carbide F24, F30, F54, and F70 are commonly adopted in flooring applications.

Green Silicon Carbide F36-F500 For SiC Abrasive tools

Green silicon carbide abrasive powder is a brittle & extreme hardness (Mohs hardness of 9.5) material. It is suitable for producing grinding wheels for processing hard and brittle material workpieces. GC F36-F500 are mostly used for Abrasive tools. For example, resin-bonded stone GC grinding wheels; Ceramic grinding wheels for bearing processing; Fiber wheels, wire drawing wheels, flexible grinding wheels, nylon grinding wheels, etc. used for polishing and polishing stone and marble.

The difference between Black silicon carbide F-Grit and P-Grit

There are differences between Black silicon carbide F-Grit and P-Grit in many aspects. Black silicon carbide P-Grit abrasive powder is specifically used in coated abrasives. For example, black silicon carbide water sanding paper, sanding sheets, sponge polishing blocks, nylon polishing wheels, non-woven grinding wheels, black diamond polishing wheels, grid grinding wheels, and other polishing products, these products use black silicon carbide P-Grit grain. Black silicon carbide F-Grit is used for bonded abrasive tools such as resin grinding wheels, diamond grinding wheels, oxalic acid Frankfurt grinding blocks, etc.
