The refractory kiln furniture, comprises ceramic surface parts (1) integrally formed with a portion of a ceramic body (2). The surfaces of the ceramics materials and ceramic body have a specified expansion coefficient, and have a resistance to chipping, which is higher than the material of the ceramic body. A rupture modulus, a resistance to maximum load and a fracture resistance of ceramic surface part is higher than a rupture modulus, a resistance to maximum load and a fracture resistance of the portion of the ceramic body, respectively. The refractory kiln furniture, comprises ceramic surface parts (1) integrally formed with a portion of a ceramic body (2). The surfaces of the ceramics materials and ceramic body have a specified expansion coefficient, and have a resistance to chipping, which is higher than the material of the ceramic body. A rupture modulus, a resistance to maximum load and a fracture resistance of ceramic surface part is higher than a rupture modulus, a resistance to maximum load and a fracture resistance of the portion of the ceramic body, respectively. The ceramic surface part and the ceramic body are made of a material based of cordierite-mullite, in which the content of cordierite is 40-80 wt.% and mullite is 2-30 wt.%. The ceramic body is molded by a ceramic composition to form a fritted ceramic article. The ceramic part and the molded body are molded separately with one another. An INDEPENDENT CLAIM is included for a process for manufacturing a refractory kiln furniture. |
