Abstract
The particulars of mechanochemical interaction in the system Ca(OH)2–Al–H2O were studied by means of x-ray phase, x-ray structural, and simultaneous thermal analyses. It is shown that the combined mechanical activation of the initial components in the ratio of Ca(OH)2: Al = 1 : 2, 1 : 4, 1 : 12 and subsequent heat treatment at 1000°C leads to the formation of aluminates with the same molar ratio. Studies of the specific surface area and mechanical strength of the synthesized samples established that calcium hexaaluminate has the highest indices.
