Apatite-structured compounds: synthesis and high-temperature investigation. (публикация автора на scipeople)   

Knyazev A.V., Chernorukov N.G., Bulanov E.N. - Materials Chemistry and Physics. , 2012
The phase transitions and thermal expansion of apatite-structured compounds with the general formula MII5(AVO4)3L (MII = Ca, Sr, Cd, Ba, Pb; AV = P, V, Cr, Mn; L = OH, F, Cl, Br, I) have been studied by high-temperature X-ray diffraction and differential thermal analysis. Polymorphic transition natu...

Development of novel high-temperature inorganic pigments. (публикация автора на scipeople)   

Knyazev A.V., Belopolskaya S.S., Chernorukov N.G., Ladenkov I.V., Bulanov E.N., Komshina M.E. - Proceedings of the 2nd International Seminar on Chemistry. , 2011
A number of inorganic pigments including a few compounds obtained for the first time were synthesized using new and optimized existing methods. A temperature interval of the synthesis is 700-1100°C, a time interval is 8-12 hours, that is acceptable for the semiindustrial production. Inorganic pigmen...

Phase diagram of apatite system Ca10(PO4)6Cl2–Pb10(PO4)6Cl2. (публикация автора на scipeople)   

Knyazev A.V., Chernorukov N.G., Bulanov E.N. - Thermochimica Acta. , 2011
Compounds in Ca10(PO4)6Cl2–Pb10(PO4)6Cl2 system were synthesized by solid state reaction. It was ascertained using DTA and X-ray diffraction methods that in the investigated system there are two fields because of the formation a compound with formula Ca7Pb3(PO4)6Cl2. The first area is the Pb10(PO4)6...

High-temperature thermal and X-ray diffraction studies, and room-temperature spectroscopic investigation of some inorganic pigments. (публикация автора на scipeople)   

Knyazev A.V., Maczka M., Bulanov E.N., Ptak M., Belopolskaya S.S. - Dyes and Pigments. , 2011
Inorganic Cr- and Mn-containing pigments of different structural types were investigated by hightemperature and spectroscopic methods. The differential scanning calorimetry in the temperature interval 298e1723 K was applied to measure temperatures of phase transition and melting of the studied compo...

Isomorphism and phase diagram of Pb5(PO4)3F – Pb5(PO4)3Cl system. (публикация автора на scipeople)   

Knyazev A.V., Chernorukov N.G., Bulanov E.N. - Thermochimica Acta. , 2011
Compounds of composition Pb5(PO4)3FxCl1−x (0≤x≤1), which are synthetic analogues of minerals pyromorphite, flourapatite, and endlichite, were synthesized for the first time by high-temperature solid phase reactions. X-ray diffraction and IR spectroscopy were used to determine the structure of the co...
