Termoref supplies electro cast mullite blocks that stand out with their excellent thermal shock resistance and low thermal conductivity. Composed of alumina (Al₂O₃) and silica (SiO₂), mullite blocks provide exceptional thermal stability in glass, ceramic, and metallurgy furnaces. They maintain their structural integrity even at high temperatures, ensuring long service life and enhanced energy efficiency.

The mullite blocks produced by Termoref feature low thermal expansion, high abrasion resistance, and strong chemical durability. Thanks to these properties, they are safely used in critical zones of melting, heating, and firing furnaces. Our company offers optimized mullite refractory solutions for every application with various density and size options.
