Refractory Porous Materials Based on Secondary Resources and Phosphate Compounds

Refractory Porous Materials Based on Secondary Resources and Phosphate Compounds Results are provided for a study of porous ceramic materials prepared in the course of chemical and exothermic reactions based on a system containing secondary resources (chamotte scrap, mullite-containing waste, aluminum smelting slag), aluminium phosphate binder, aluminum refractory clay, and various additives. Temperature dependences are established for heat capacity and thermal conductivity in the range 30 – 1000°C for the material obtained. It is shown that the optimum overall aluminum and slag content in a mixture for preparing porous materials is 10 – 20%. It is established that addition of magnesite and chrome-magnesite, and also ammonium dihydrophosphate, makes it possible to control density and strength of the materials obtained. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

Results are provided for a study of porous ceramic materials prepared in the course of chemical and exothermic reactions based on a system containing secondary resources (chamotte scrap, mullite-containing waste, aluminum smelting slag), aluminium phosphate binder, aluminum refractory clay, and various additives. Temperature dependences are established for heat capacity and thermal conductivity in the range 30 – 1000°C for the material obtained. It is shown that the optimum overall aluminum and slag content in a mixture for preparing porous materials is 10 – 20%. It is established that addition of magnesite and chrome-magnesite, and also ammonium dihydrophosphate, makes it possible to control density and strength of the materials obtained.
