Classification of refractory material Classification of refractory materials Refractory materials are classified in various ways according to (i) chemical composition, (ii) chemical properties of their constituent substances, (iii) according to the place of use, (iv) refractory material, (v) manufacturing method, and (vi) The physical form, (vii) according to the application, (viii) according to the thermal conductivity, (ix) according to the main characteristics of the matri

Properties of Refractory Materials Important characteristics of refractory materials include chemical composition, bulk density, apparent porosity, apparent specific gravity, and resistance to atmospheric temperature. These characteristics are often used as "checkpoints" during manufacturing and quality control. The chemical composition is the basis for the classification of refractory materials, and the density, porosity, and strength are affected by many other factors. Thes

Homogeneous refractory materials are mechanical mixtures of refractory materials that act as aggregates, adhesives, metallic materials, or other desirable product properties. The mixing of materials causes physical and chemical reactions during installation and during the molding of prefabricated objects, not during use. Monolithic refractory differs from refractory bricks is that they are not cast or fired before use, although the chemical and physical properties show simila
