Silicon Carbide

Silicon Carbide is manufactured from a high heat reaction of silica sand and carbon. While silicon carbide and silica share similar chemistry, Silicon Carbide used in abrasive blasting contains less than 1% free silica. Free silica or silicon dioxide is the compound that should be avoided (due to risk of silicosis) and not inhaled as a fine particulate. Details about Silicon Carbide can be found on a previous post.
