Soluble Sodium Silicate Manufacture

Soluble Sodium Silicate Manufacture

Sodium silicates are produced in a two or th ree step process, depending on the desired end products of the waterglass. Step 1 - Cullet production Na2CO3 and SiO2 (from sand) are fused at 1100 - 1200 oC to produce an amorphous solid glass known as cullet, consis ting of a mixture of SiO 2 and Na 2O. This is done in Australia,

The Manufacturing Process The basic process heats silica and coke in a submerged electric arc furnace to high temperatures. High temperatures are required to produce a reaction where the oxygen is removed, leaving behind silicon. This is known as a reduction process. In this process, metal carbides usually form first at the lower temperatures.

Silica Sand - An Overview | Sciencedirect Topics

To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and “autoclaved” at about 170 C (340 F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.
