The Characteristics of SilicaSol Coining Refractories

Traditionally calcium aluminate cement is always used as the binding agent for refractory castable applied in steel and iron but cement contains many impurities it is easy to generate lowmelting additives and excessive liquid phase may be formed in material calcination so the thermal shock resistance and moderate temperature intensity of corundum castables bonded with

Types of Refractory Materials and Their Appliions

Silica Pure silica melts at a very high temperature namely 1713°C but when it comes in contact with alkaline substances it forms silies some of which melt easily Therefore the presence of alkali in silica used as a refractory material should be avoided Silica occurs in the form of quartzite Dinas rock and ganister Ganister is a rock with a high content of natural silicon
