A multicolor light-storing ceramic for fire-protection indication and a preparation method thereof are provided. The preparation method includes: adding a glass based raw material, a light-storing powder, a dispersant and an alumina powder into a granulator, adding water mixed with a pore-forming agent and then mechanically stirring for granulation; adding a plasticizer after the stirring of 4˜8 h, and continuing the stirring for 1˜3 h to thereby obtain a mixture; packing the mixture into a mold and performing tableting; demolding and obtaining a light-storing self-luminous quartz ceramic by drying and firing using a kiln; printing a pattern onto a surface of the ceramic and then curing to obtain a light-storing ceramic for indication sign. Using an industrial waste glass has advantages of low sintering temperature and green environmental protection; dispersed pores and alumina introduced as scattering sources improves light absorption efficiency, fluorescence output phase ratio and light transmission of the ceramic.

Thermal spray powder including a metal and/or ceramic powder composition and porosity forming fibers and/or fiber agglomerates mixed within or with the powder composition. An exemplary TBC or abradable thermal spray coating can be made by the thermal spray powder.

A method for fabricating a porous ceramic heating body, and a method of fabricating a heating body. The method for fabricating includes, in sequence, mixing, ball-milling, defoaming, molding, and drying, pore-forming agent discharging, sintering, and electrode leading. The whole method is simple, and by using a box furnace to sinter the green body under an oxidizing atmosphere and normal pressure, the fabricated ceramic heating body is heated uniformly and the heating efficiency is high.

A ceramic honeycomb body exhibiting a primary phase of aluminum titanate solid solution with a pseudobrookite structure, and a secondary phase of cordierite. The ceramic honeycomb body contains the aluminum titanate solid solution in an amount greater than or equal to 50 wt. % and cordierite in an amount greater than or equal to 20 wt. %.
