Thermogravimetrical Study of Chloromolibdenum Gadolinium GdMoO4Cl within the Temperature Range 25-1500°C in Air

The thermostability of GdMoO4Cl within the temperature range 25-1500°C was studied by DTA, X-ray powder diffraction, and chemical and optical methods. The compound is relatively stable up to 470deg;C; it exhibits polymorphic transformation at 1030°C. This suggests the decomposition scheme to polyphase products: matrix presented Compounds of composition LnWO4Cl and Ln3WO6Cl3 identified by X-ray powder diffraction and some physical and chemical methods were reported to form in solid phase reaction [1-3]. The compounds can be applied in laser technology as efficient phosphor. We reported the optimum conditions for synthesis [4], luminescence, spectral and optical properties [5-7]

Thermostability of GdMoO4Cl within temperature range 25-1500 degrees C was studied by DTA, X-Ray powder diffraction, chemical and optical methods. Compound is relatively stable up to 470 degrees C, it exhibits polymorphic transformation at 1030 degrees C. This suggests the decomposition scheme to polyphase products: 4GdMoO(4)Cl O-2 --> -2Cl(2) Gd-2(MoO4)(3) + Gd2MoO6. Compounds of composition LnWO(4)Cl and Ln(3)WO(6)Cl(3) identified by X-Ray powder diffraction and some physical and chemical methods were reported to form solid phase reaction [1-3]. The compounds can be applied in laser technology as efficient phosphorous. We reported optimal conditions for synthesis [4], luminescence, spectral and optical properties [5-7]
