REFRACTORY BRICKS
Magnesite refractories are containing at least 97% magnesium oxide and one of the most widely used basic refractory bricks.
High alumina description generally means content of alumina percentage is higher than 45.
Silica bricks are prepared by kiln-firing quartz of low impurity content at a temperature of 1450°C, thereby converting at least 98.5% of it into a mixture of the more 'open', less dense forms, tridymite and cristobalite.
A fire brick is a special type of brick made using fire clay and has a good resistance against high temperatures which are used in kilns, lining furnaces, fireplaces and fireboxes
Made from fire clay containing 50% of chrome iron ore, 30% iron oxide (Ferrous oxide) and 20% bauxite with little silica. - Resists temperature up to 2000℃
