Rice Husk Ash
High-silica Rice Husk Ash (85–92% SiO₂) — micronized ground powder, steel-grade granules and pellets for concrete, cement, refractory and steel. NABL tested. Bulk supply & export from Odisha, India.
Rice Husk Ash (RHA) is the amorphous, silica-rich material produced by the controlled combustion of rice husk. Its high reactive-silica content makes it a valuable, lower-carbon input for concrete and cement, refractories, and Rice Husk Ash for steel — as an insulating tundish and ladle covering compound in steelmaking.
Ambika Biotech manufactures RHA in three forms — micronized ground powder, free-flowing granules and dust-free pellets — each engineered to a consistent, NABL-tested specification with reliable bulk capacity and full export documentation.
