refractory

Refractory materials, which can withstand high temperatures for a long time and therefore have many industrial uses.  materials areRefractories; It is generally used in the construction of furnaces, reactors, igniters and furnaces. A refractory material is resistant to thermal shocks.  must be resistant. should not contract or expand when exposed to high heat. It must preserve its chemical structure and  There should be no cracks on it. It is possible to divide refractories into three groups as acidic - neutral - basic.
