Embodiment 1
[0024] A low-zirconia mullite duct brick, which is composed of the following raw materials in parts by weight: fused mullite: 50 parts; zirconia: 20 parts; Guangxi white clay: 5 parts; andalusite: 20 parts; kyanite Stone: 3 parts; Lignin: 2 parts.
[0025] The preparation method of this low-zircon mullite duct brick is as follows:
[0026] a. Mix fused mullite, zirconia, andalusite and kyanite in proportion and then pulverize or mix in proportion after pulverization to obtain mixed particles. The mixed particles are, by weight percentage, with a particle size of 200 mesh Particles account for 50~60%, particles with a particle size of 1~3mm account for 30~40%, particles with a particle size of 3~5mm account for 5~10%;
[0027] b. Grind the mixed particles obtained in step a into 200 mesh Guangxi white clay and have a density of 1.22~1.25g / cm 3 The lignin aqueous solution is mixed in proportion to obtain a mixed raw material;
[0028] c. pressing the mixed raw mat...
