Calcium magnesium silicate

Calcium magnesium silicate (CAS 13813-64-4) is an inorganic mineral salt used across industrial sectors as a rheology modifier and functional filler. It influences flow behavior, texture, and structural consistency in formulated products.

In agriculture and animal feed, it functions as a flow agent and anti-caking additive in powdered fertilizers and feed blends. This prevents clumping during storage and handling, ensuring consistent distribution of nutrients.

Construction applications include use as a filler and rheology modifier in cementitious systems, mortars, and grouts. In these environments, it helps control workability and reduce shrinkage during the curing process.

In plastics and polymer compounding, it acts as a mineral filler that modifies melt viscosity and improves dimensional stability. This makes it a valuable component for manufacturers producing high-precision finished parts.

Specialty coating and sealant formulations also incorporate this mineral to adjust application consistency and reduce settling. It ensures that pigments and other solids remain suspended throughout the product shelf life.

The material is supplied as a fine white powder, with particle size distributions tailored to specific processing requirements. Technical grade is the standard commercial offering for most industrial applications.

Specifications vary by supplier based on silica content, purity, and mineral composition. Bulk and bagged formats are available to suit both large-scale industrial users and smaller compounding operations.
