Why is silicon carbide added to some floor tiles?

Silicon carbide is added to certain floor tiles primarily to enhance their durability and safety. Because it is an exceedingly hard material—with a Mohs hardness rating of 9, approaching that of diamond—incorporating it into tiles significantly increases their resistance to wear and abrasion.

Beyond its extreme hardness, silicon carbide is valued for its high-temperature strength and thermal shock resistance. In flooring applications, these properties help maintain the structural integrity of the tile under heavy use or in demanding environments. Furthermore, the inclusion of these hard crystals creates a textured, slip-resistant surface, which is a critical safety feature in industrial or high-traffic areas where traction is essential.12
