XZK Group's refractory martar including Corundum mortar, corundum mullite mortar, zircon mullite mortar, zircon mortar, sillimanite mortar, mullite mortar, ZKM-1, ZKM-2. High adhesion & sealing, erosion resistant.
Refractory mortar, also known as refractory mud or jointing material, is a high-temperature resistant paste or mixture, typically composed of materials like fireclay, high-alumina cement, silica, or magnesia-based compounds, corresponding to the brick type it serves. It is characterized by its excellent workability, suitable plasticity, and strong adhesive strength after drying and sintering. Key properties include:
