Manganese-substituted tricalcium phosphates (TCPs), Ca3(PO4)2, containing 0–1.49 wt % manganese have been prepared by heterophase synthesis using mechanical activation. The percentage of manganese has been determined by inductively coupled plasma a

We present the calculated and the experimental mass spectra of alkali metal tungstates within the temperature range of 1100–1500 K and determine the vapor pressures and the thermodynamic properties of gaseous alkali metal tungstates.

It is shown that the molecular composition of the vapor–gas phase of many chemical compounds and their mixtures, including carbides, nitrides, and oxides, is substantially more complex and diverse than it appeared before. In addition to monomeric m
