One particular important issue to keep in mind is that silicon carbide is the popular grit for rock tumbling. The popular grit for rock tumbling is silicon carbide because of its hardness and ability to wear down and smooth out the rocks effectively.
Simply preserve adding new coarser grit, and as the media breaks down, it will create a "working blend" of assorted sized particles. This permits for effective surface cleaning/polishing. SiC is harder than aluminum oxide, but a tiny bit more friable than brown fused AO.

This circumstance assumes that the most recent demand curve, production capacity, and EV laws will persist.

Oxidation: SIC will not oxidize until it reaches a temperature of ~1200C. If it was put in a very harsh environment, such as an acid fog then it would oxidize earlier. You may see a slight color alter when the material is wet vs dry.
Aluminum oxide also has high hardness, but it fractures into more rounded points. This makes it perfect for gently polishing rocks during the ultimate stage. Using the appropriate combination and sequence of these two grit types is essential to accomplishing beautifully polished stones.
Silicon carbide whiskers have a high tensile strength and therefore are used in composites; very pure crystals are used as semiconductors. Formula: SiC
Extra coarse grit just isn't proposed for tumbling because it is just too abrasive and will damage your rocks.
Medium. Medium grit is used to smooth the surface of stones. It is actually smaller than coarse grit and is generally made of aluminum oxide.
You will probably waste a lot of time and electricity trying to save revenue using sand in lieu of rock tumbler grit. We have an article titled "Can I Use Sand As an alternative to Grit?" that silicon carbide pipe explains all this in much more detail.
It's also important to note that some rocks are harder than others and will need different grit progression and longer tumbling time.
