Sinter Grade Boron Carbide Description:

Sinter Grade Boron Carbide Powders are specially sized to aid in the manufacturing of sintered ceramic parts. They are typically fine powders with an average particle size of fewer than 10 microns and a specially tailored size distribution.

Features:

-High Hardness

-Abrasion / Wear-Resistance

-Fracture Toughness

-Chemical Inertness

-High Neutron Absorbing Cross Section
