Pigments of cerium-praseodymium type have not been well known. They are of interest with respect to their colour hues in ceramic glazes, and are based on the incorporation of praseodymium ions into the host lattice of cerium dioxide. We have now stud

Two methods are given for assessment of density of binary aqueous solutions of electrolytes; one is based on partial molar volume of the dissolved electrolyte at infinite dilution, and the other is based on additivity of apparent molar volumes at a g

Methods of thermal analysis (DTA and chemical analyses of pigments calcined at various temperatures) have been used for the determination of the temperatures of formation of the structures CaSnO3, CaSnSiO5 and CaSiO3. CaSnO3 and CaSiO3 are formed at

A ceramic spinel pigment of Zn-Fe-Cr type has been used for demonstration of application of thermoelectrometry to evaluation of suitability of the Fe 2 O 3 raw material. Conductometrical thermal analysis very sensitively indicates the beginning of th

Relations are presented for estimating the density of ternary aqueous solution on the basis of known densities of binary solutions of both components of the ternary solution. Accuracy of the estimation is tested using both the diluted and concentrate

Calcination of a mixture of copper (II) oxide and phosphoric acid (mol. ratio CuO/P2O5 = 1) produces dicopper (II) cyclo-tetraphosphate as the main product. At first, various intermediates of the type of simple copper (II) phosphates are formed. Then
