It is a very soft (friable) silicon carbide grinding wheel formulated for grinding tungsten carbide. Because tungsten carbide is so hard, silicon carbide, nowhere nearly as hard as diamond, although very hard, dulls quickly. The soft bond of the wheels permits the dull grains to shed quickly, presenting (hopefully) sharp grains to the …

A fairly simple chemical test for any tungsten ore is to grind to a fine powder and boil with concentrated hydrochloric acid for 15 minutes. If tungsten is present, the solution turns cloudy yellow and will turn blue if a piece of aluminum, zinc, solder, or tin is added. The yellow residue is soluble in ammonia.
