Low Silica Dolomite
Low Silica Dolomite Powder Manufacturer, Supplier & Exporter in Rajasthan, India
Unlike dolomite, Low Silica Dolomite is a specialized additive known for its purity and negligible silica content. It is widely used in industries that require minimal silica content in their raw materials. Silver Stone Industries manufactures and supplies low silica dolomite powder from India.
What is Low Silica Dolomite?
Low silica dolomite is a finely processed mineral primarily composed of calcium carbonate (CaCO₃) and magnesium carbonate (MgCO₃) with significantly reduced silica (SiO₂) content. The low-silica presence ensures superior thermal stability of final products without affecting their quality. It is used as a filler and extender across various industries, such as steel manufacturing, glass production, refractories, and agriculture.
At Silver Stone Industries, you can find low silica dolomite powder with less than 1% silica. Sourced in superior quality from Rajasthan, SSI exports low silica dolomite across India and internationally, including markets in the United Arab Emirates (UAE), Jordan, Qatar, South Sudan, Bangladesh, Saudi Arabia, Sri Lanka, and beyond.
What Makes Low Silica Dolomite Powder Unique?
The minimal silica presence makes low silica dolomite powder different from other mineral additives and fillers. The purity of dolomite and the non-interference of silica impurities make the powder highly resistant to temperature extremes. Further, the balanced composition of calcium and magnesium in pure dolomite improved the metallurgical efficiency of the powdered filler. With fine particle size, low impurity levels, and high brightness, it is a preferred raw material in refractory and industrial applications.
