Silicon Carbide Shapes and Powders

Superior Graphite produces silicon carbide in a Beta crystalline form made by a unique, continuous electro-thermal process, developed for large scale production. The reactants are silica sand and solid carbon, which are converted in a continuous process. A unique microcrystalline Beta product results, suited for making fine microgrits and ultra-fine ceramic grade silicon carbide powders. These powders are perfect for use in Toner and Advanced Ceramic Part production.

Besides green Beta powders, green Alpha silicon carbide sub-micron powders are also produced, using the same state-of-the-art milling techniques to reduce course Alpha SiC grit to highly sinterable sub-micron powders. These powders are designed specifically for use in the Advanced Ceramic Industry, including wear parts and ceramic armor.

Protect Tiles® (Ceramic Armor)

Ceramic Armor Tile

Superior Graphite, with a history in the silicon carbide powder business, chose this ceramic to make its armor tiles. The “ceramic of choice for the future,” is literally between other recognizable alumina and boron carbide armor tiles in price and weight. However, when combined with overall ballistic performance, silicon carbide Protect Tiles® will earn the lead position. Certain ballistics will pass through B4C tiles but SiC tiles will stop them, and SiC is 20% lighter than an alternative Al2O3 tile.

These high density silicon carbide sintered tiles are economical due to their processing, versus hot pressed pressure-assisted tiles. The latter are fine for most body armor applications, but too expensive for covering large areas of protection. Protect Tiles®, are 55% lighter than armor grade steel for equal protection, so are therefore a logical part of a functionally graded armor solution for vehicles and aircraft.

Protect Tiles® are available to be ballistically qualified in various sizes and shapes, that can also be custom produced to meet customer demand.
