Synthesis and characterization of thorium phosphate phases by spray pyrolysis: chemistry of thorium phosphates
Autor: L. Marchin, J.C. Trombe, M. Verelst
Publikováno v: Materials Research Bulletin. 39:1973-1983
This paper describes the synthesis of some thorium phosphate compounds with different Th/P ratio (1/2, 2/3 and 3/4) by a spray pyrolysis technique. The so-prepared rough compounds were annealed at different temperatures for 2 h and then analyzed by m

Synthese et structure cristalline d'un nouveau silicate de lanthane et de titane
Autor: A Mosset, J.C Trombe, D Benbertal
Publikováno v: Materials Research Bulletin. 29:47-54
La 2 Ti 2 SiO 9 has been synthesized by chemical transport reaction using the system LaOCl and TiO 2 in a temperature gradient; the silicium atoms came from the silica tube. Its structure was determined and refined down to R = 0.021 for 1041 observat

Some features of the incorporation of oxygen in different oxidation states in the apatitic lattice—II On the synthesis and properties of calcium and strontium peroxiapatites
Autor: J.C. Trombe, G. Montel
Publikováno v: Journal of Inorganic and Nuclear Chemistry. 40:23-26
New apatites: peroxiapatites, containing in their lattices oxygen in an oxidation state — I, are found with calcium and strontium phosphate apatites. The oxygen (-I) containing groups are peroxide ions, which are associated with vacancies. Peroxiap

On the existence of bivalent ions in the apatite channels: A new example—Phosphocalcium cyanamido-apatite
Autor: J.C. Trombe, G. Montel
Publikováno v: Journal of Solid State Chemistry. 40:152-160
A new apatite, phosphocalcium cyanamido-apatite Ca 10 (PO 4 ) 6 CN 2 □, is obtained by treatment under low pressure at high temperature (900–1000°C) of a mixture of the corresponding hydroxyapatite and calcium cyanamide. In this apatite, one CN

Some features of the incorporation of oxygen in different oxidation states in the apatitic lattice—I On the existence of calcium and strontium oxyapatites
Autor: J.C. Trombe, G. Montel
Publikováno v: Journal of Inorganic and Nuclear Chemistry. 40:15-21
The existence of calcium phosphate oxyapatite, which has been denied for a long time, is demonstrated: this compound exists only under a vacuum (10 −4 to 10 −6 torr) or in sufficiently waterfree gases (He, N 2 ), in the range of temperatures 850
