2.2.1.3 Types of Diffusional Processes There are various types of diffusional processes depending on the medium in which the diffusion occurs. 2.2.1.3.1 Diffusion in Molten Slags and Glasses Because of the ionic nature of the medium the diffusion in molten slags and glasses is by the ions. The ionic conduction is a purely random jump process.

· Basic refractories have the attributes of being relatively inexpensive compared to other bricks (special carbon refractories zircon zirconia fused-cast refractory). In addition they can be used in several applications as the following coating of laboratory furnaces refractory supports thermal insulating industrial ceramics concrete chemical producers and especially in the steel sector.

· The refractory materials normally used for lining are dolomite bricks magnesia chrome bricks magnesia carbon bricks high alumina bricks aluminum carbon bricks and high alumina castable. The types of refractory construction vary widely depending on the operating conditions and on the ability to cycle STLs rapidly.
Review on the elaboration and characterization of ceramics
· Actually there are two methods to produce refractory by using dolomite and magnesite as materials one is fired in rotary or shaft kilns up to dead burning temperatures of 1500–1800 °C the other is produced by electric smelting furnace with a temperature over 2500 °C for example burned magnesite (i.e. fused magnesia) and electrocast spine are produced by electric smelting furnace.
