Points : Refractory Materials, Definition Definition Refractories are those ceramic materials, which are particularly useful for their resistance to high . temperatures and can withstand furnace atmosphere. Refractory materials must with stand high temperatures. Most of the, high melting point pure ceramic materials qualifies as refractory materials; however, the pure oxide refractories are expensive and difficult form in to useful shapes.Instead typical refractories are composed of coarse oxide particles, are grog, bonding by a finer refractories material. The final materials melt during firing, providing bonding. Typical refractories bricks contain about 20-25% apparent porosity, improving thermal insulation.
