Abstract:

The thermal reduction of CaO with Al was studied under 10-3 mmHg of pressure and in the range of 1040 to 1195°C. The composition of products was analyzed with a X-ray spectrometer using the internal standard method.
Products were found to be the calcium aluminate of the formula 3CaO ⋅ Al2O3, 12CaO ⋅ 7Al2O3 and CaO ⋅ Al2O3. From these results, the following reactions were assumed:
