USAHigh alumina-chromia plastic refractory mix
A new and improved high alumina-chromia plastic refractory mix is provided wherein the predominant aggregate component of fused alumina imparts a strong skeletal aggregate structure of superior uniform heat stability. The matrix is comprised predominantly of materials having a high specific surface area of at least about 0.1 sq. m./g. high purity and a trigonal phase solid solution upon firing.

Lining (Refractory)an overview ScienceDirect Topics
Feb 01 2011 · The sintering zone (the burning zone) is characterised by high-temperature (1500–1800°C) corrosion and extreme wear on the refractory lining. For this zone magnesia–spinel or magnesia–chrome bricks or less commonly magnesia-enriched dolomite are used. The burning zone of a rotary cement kiln is normally lined with basic bricks.

HOW TO CLASSIFY REFRACTORY MATERIALS
Basic refractories arethose which are attacked by acid slags. Since they do not react with basic slags so these refractories are of considerable importance for furnace linings where the environment is basic for example in furnace for non- ferrous metallurgical operations. Examples of basic refractories are 1. Magnesite. 2. MagChrome. 3.
