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

Carbon is an element that can exist in three forms in nature: diamond, graphite, and carbon. Carbon has excellent fire resistance properties, such as slag non-wetting properties and high thermal conductivity. It can be used as a refractory material in two ways: as an additive or binder (coal tar, petroleum pitch, or resin) in carbon-containing refractories, and as an additive in carbon-based refractories. Carbon-containing refractories are made by mixing graphite or carbon in
