Sodium Silicate
Sodium silicate quartz is the core silicon dioxide source melted together with soda ash in the production of water glass (sodium silicate). Sodium silicate is a versatile chemical used across the detergent, paper, foundry binder, water treatment and adhesive sectors, and its quality depends largely on the SiO₂ purity of the quartz used. High-purity quartz (typical SiO₂ 99.8%) supports a consistent modulus and quality sodium silicate production.
How to Choose Sodium Silicate Quartz
Several criteria define sodium silicate quartz. SiO₂ purity is the most important property; because the SiO₂/Na₂O modulus of sodium silicate depends directly on the purity of the quartz, high purity gives a stable product. A low iron and impurity content preserves the colour and clarity of the final sodium silicate. Controlled grain size ensures the quartz reacts smoothly and homogeneously with soda ash. A stable composition delivers the same modulus from batch to batch.
Recommended Product for Sodium Silicate
Granular quartz with a controlled gradation is used in sodium silicate production. We can determine the suitable product together, based on your target modulus and furnace system.
About Sodium Silicate
How is sodium silicate produced?
High-purity quartz is melted with soda ash at high temperature to obtain sodium silicate (water glass).
How does quartz purity affect sodium silicate?
The product's SiO₂/Na₂O modulus and clarity depend directly on the purity of the quartz; high purity gives a stable product.
Where is sodium silicate used?
It is used across many sectors, such as detergents, paper, foundry binders, water treatment and adhesives.
Which grain size is suitable for sodium silicate?
Granular quartz with a controlled gradation is used for a homogeneous reaction with soda ash.
