Reaction-bonded silicon carbide (RB-SiC) is a composite ceramic that comprises of hard SiC grains and brittle Si matrix. Surface texture with well machining qualities, in particular, is difficult to be fabricated on RB-SiC in conventional machining conditions since the removal of material inevitably induces some unexpected surface defects.

In the production of silicon carbide, a mixture of carbon material (usually petroleum coke) and silica or quartz sand is chemically reacted at high temperatures in an electrically resistive furnace to form SiC. The resulting crude material is further processed by crushing and milling to obtain the correct shape and size of SiC grains.

I use silicon carbide soldering grains (I call the product soldering sand) all the time. It is a wonderful way to hold up the article that you are soldering and have the object placed to be joined exactly where you want it; it allows you to have the join in the exact spot to be soldered.

Silicon carbide (SiC) is typically present at levels of about 10 ppm. Individual grains of silicon carbide up to 30 micrometers across have been isolated (Fig. 2), and some have even been observed in situ in chondrite matrix. Noble gas isotopic anomalies suggest that most SiC grains were formed in the outflows from AGB stars.

The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating it with graphite at 1500°C (2730°F). The material formed in the Acheson furnace varies in purity. The silicon carbide “stones” and grains are turned into a fine powder by crushing, and then purified with halogens.
