High-quality rice husk ash (RHA), which is well-suited for use in the steel industry, particularly as an insulator in tundish linings and as an effective slag conditioner.
Our RHA is produced from carefully selected rice husks through a controlled combustion process, ensuring low carbon content, high silica concentration, and consistent particle size all critical factors for industrial-grade applications. often used in cement, concrete, refractory materials, and as a pozzolanic material.
