High Quality Silicious Material Refractory Mortar
The Description:
Fire clay clay is referred to as soft clay. It is a kind of refractory clay with plasticity. The main constituent minerals are kaolinite, kaolinite, hydromica and so on. Generally containing Al2O3≥22% ~ 30%,Si02≥42% 73%, refractoriness 1580 ~ 1670ºC. This fireclay becomes soft in water, and can be made into various shapes after water, and is the raw material for making refractories, as a binder and in hard fireclay. According to the chemical composition of soft fireclay (useful components, harmful components), physical properties (refractoriness, plasticity, burning loss, etc.) can be divided into three grades, II, III
