how to process silicate raw materials

Alumina Silicate

Accordingly, both the raw material and the machining process are highly expensive. Conversely, raw alumina silicate can be machined very easily using conventional tools. Machining costs are therefore low, as is the cost of the raw material. Thereafter, thermal withstand is achieved by heat treatment at 940 °C, 1,100 °C or 1,300 °C.

Calcium Silicate

Calcium silicate (CS) foam boards (Fig. 8.5) made with slightly different raw materials are also known as mineral foam or mineral insulating boards. The raw materials for CS are calcium and silicon dioxide plus an aggregate of 3–6% cellulose. These are mixed with water to form a slurry and this produces calcium silicate hydrate.
