Industrial Calcium Oxide (CaO) Manufacturer in India
High-Purity Calcined Calcium Oxide (CaO) Lumps and Powder for Chemical Industries
Satya Bharat Minerals is a specialized Calcium Oxide (CaO) manufacturer and supplier in India. Commonly known as burnt lime, quicklime, or calx, our Calcium Oxide is synthesized through thermal decomposition (calcination) of high-grade calcium carbonate (CaCO₃) in automated vertical shaft kilns in Nagaur, Rajasthan. We supply industrial-grade CaO with up to 95% chemical purity in lump, crushed grit, and micronized powder formats, catering to metallurgical smelters, chemical synthesis plants, environmental desulfurization units, and glass factories nationwide.
Direct kiln dispatch from Nagaur, Rajasthan plant to industrial sites pan-India.

Industrial Calcium Oxide (CaO) - FAQs
What industries require high-purity Calcium Oxide (CaO)?
Calcium oxide is essential in primary steelmaking (slag conditioning and dephosphorization), glass manufacturing (fluxing silica), chemical synthesis (calcium carbide, chlorinated lime), paper and pulp (kraft recovery cycle), and environmental flue gas scrubbing.
How should Calcium Oxide (CaO) be stored and handled?
Because CaO reacts exothermically with ambient moisture and carbon dioxide to hydrate and carbonize, it must be stored in dry, covered warehouses in moisture-barrier bags or sealed silos. Protective PPE (gloves, dust masks, goggles) is required when handling.
