Cast irons contain appreciable amounts of silicon, normally 1 to 3 wt%, and consequently these alloys should be considered ternary Fe-C-Si alloys. Despite this, the principles of cast iron solidifiion are understood from the binary iron-carbon phase diagram, where the eutectic point lies at 1,154 °C (2,109 °F) and 4.3 wt% carbon.

Silicon carbide has a very fast cutting speed and can be recycled and reused many more times than sand. The hardness of silicon carbide allows for much shorter blast times relative to softer blast media. Silicon carbide grit is the ideal media for use on glass and stone in both suction or siphon and direct pressure blast systems.

Carbide | chemical compound | Britannica

Carbide, any of a class of chemical compounds in which carbon is coined with a metallic or semimetallic element. Calcium carbide is important chiefly as a source of acetylene and other chemicals, whereas the carbides of silicon, tungsten, and several other elements are valued for their physical hardness, strength, and resistance to chemical attack even at very high temperatures.
