Superior Graphite, with a history in the silicon carbide powder business, chose this ceramic to make its armor tiles from. 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 later 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.

Ballistic Limit Behavior of Hot Pressed Silicon Carbide (A-SiC and C-SiC)
and Silicon Nitride Ceramic Tiles vs. Superior Graphite (SGC) Pressureless Sintered SiC Tile

This chart shows relative results of equal thickness tiles, bonded to 2.5 cm
5083 aluminum plate, under the same conditions and test round, showing
at what velocity failure to stop the round occurred. Sintered SiC deserves
to be recognized as a competitive alternative to former popular expensive
ceramic armor products.
