Aorthite refractory material with closed-cell structure and preparation method of anorthite refractory material
The invention provides an anorthite refractory material with a closed-cell structure and a preparation method thereof, the lightweight anorthite refractory material, especially an anorthite cast brick, has a specific microstructure, has an anorthite and mullite composite crystal phase, takes an anorthite phase as a main crystal phase, and the proportion of the crystal phase reaches 90% or above; the porous material has a closed pore structure, the pore size distribution is uniform, the porous material has a specific pore size distribution range (the pore size is 500-700 microns, and the pore size distribution is uniform), and the internal true porosity is 80% or above; the anorthite and mullite composite crystal phase is provided, the volume density is controllable, and the volume density is low; meanwhile, the material has relatively good compression strength and excellent heat-conducting property. Experimental results show that the volume density is about 0.48 g/cm < 3 >, the compression strength is 2.0 MPa or above, the heat conductivity coefficient is 0.18 W/(m.K) or below, and the use temperature is 1100-1230 DEG C.
