About Dolomite

Combining calcium and magnesium carbonate in a naturally occurring mineral structure, Dolomite serves as a functional filler and mineral raw material across coatings, polymers, rubber, glass, ceramics and construction applications. Its hardness, controlled particle size and chemical stability support dimensional stability, surface finish and formulation consistency. In glass and ceramic systems, its calcium and magnesium content contributes to composition control and processing performance.
