Refractory bricks in a torpedo car used for hauling molten iron In materials science , a refractory (or refractory material ) is a material that is resistant to decomposition by heat or chemical attack and that retains its strength and rigidity at high temperatures . [ 1 ]
Calderys, a subsidiary of Imerys, is a multinational company specialized in producing heat resistant monolithic refractory products. [1] Calderys is headquartered at Issy-Les-Moulineaux on the outskirts of Paris, with over 2,000 employees and 18 plants in more than 30 countries.
In the making of firebrick, fire clay is fired in the kiln until it is partly vitrified.For special purposes, the brick may also be glazed. There are two standard sizes of fire brick: 9 in × 4 + 1 ⁄ 2 in × 3 in (229 mm × 114 mm × 76 mm) and 9 in × 4 + 1 ⁄ 2 in × 2 + 1 ⁄ 2 in (229 mm × 114 mm × 64 mm). [2]
These opposing effects result in groups 5 through 7 exhibiting the most refractory properties. [8] Creep resistance is a key property of the refractory metals. In metals, the starting of creep correlates with the melting point of the material; the creep in aluminium alloys starts at 200 °C, while for refractory metals temperatures above 1500 ...
