Classification of Refractories

Based on chemical composition Acidic refractoriesThey consist of mostly acidic materials like alumina (Al 2 O 3) and silica (SiO 2).They are not attacked or affected by acidic materials but easily affected by basic materials e.g. -silica alumina fire clay refractories etc.

Pores their classification and role in actual refractory

Nov 18 2011 · Refractory objects are a common case of a solid with pores which serve as a source of valuable information about many material and object properties. Present in practically all structural elements (in coarse grains in a binder and between coarse grains and binder) pores may occupy from 90 to an extremely small volume of a refractory.
