The stability of thermal units at extreme temperatures starts with the quality of the raw materials. It is the components of the refractory mix that determine how long the lining of furnaces, ladles, and reactors will withstand thermal shock, slag corrosion, and mechanical stress. Below are the key groups of raw materials Alventus supplies for refractory production.
Main Raw Material Groups
Each material solves a specific task in a refractory product formulation. Choose the group you need to go to the corresponding catalogue section.
- Refractory Minerals – natural and synthetic raw materials with high thermal resistance and volume stability. Includes kyanite, bauxite, and spinel, which provide resistance to thermal cycling and mechanical strength of the refractory framework.
- Aluminas – high-alumina materials for increasing refractoriness and corrosion resistance. Our range includes tabular, calcined, and reactive aluminas, allowing you to control density, strength, and microstructure of finished products.
- Calcium Aluminate Cements – fast-setting and high-strength binders for unshaped refractories. Represented by grades GÓRKAL 40, GÓRKAL 50, GÓRKAL 70, and GÓRKAL 80 with varying Al₂O₃ content, enabling precise composition selection for service conditions.
