Refractory Elements In Ghana
refractory product
Refractory material is a kind of inorganic nonmetallic materials with no less than 1580 but only the degree of fire resistance can be defined as a comprehensive description of the refractory and 1580 is not absolute Is now defined as the physical and chemical properties which allow the use of materials in high temperature known as refractory materials
