Choice of regime of heat treatment for unfired refractories on phosphate binder
Tóm tắt
The data of DTA, IR spectroscopy, x-ray phase analysis, and chemical analysis are used to substantiate the temperature regime for heat treatment of unfired chamotte articles. It is shown that the desired strength and water resistance are provided by the formation of alumophosphates insoluble in water
