Refractory Materials


Sintered Dolomite is a valuable refractory raw material, renowned for its durability and resistance to heat and chemical attack. Produced through a high-temperature heat treatment process known as sintering, the result is a hardened, crystalline material composed mainly of calcium magnesium carbonate. This material serves as a key ingredient in the manufacture of refractory linings for high-temperature industrial furnaces, kilns, and incinerators, thanks to its superior thermal stability and resistance to chemical erosion. Sintered Dolomite also finds use in the production of flat glass and specific types of cement, where it contributes to enhanced product properties. Our Sintered Dolomite is processed under rigorous quality control measures, ensuring consistent, high-quality performance for your most demanding applications.
