标题:High Temperature Chemical Process For The Preparation Of Cesium Tungstate
发明人：CARDARELLI FRANCOIS
权利人:CARDARELLI FRANCOIS
摘要:The present disclosure broadly relates to a high temperature chemical process for the synthesis of cesium tungstate in the solid state and the preparation of aqueous solutions or deuterated solutions of cesium tungstate. More specifically, but not exclusively, the present disclosure relates to a high temperature chemical process in which tungsten oxide compounds such as tungsten oxides, or natural or synthetic concentrates such as wolframite or scheelite, tungsten industrial by-products or there mixture thereof, are mixed with cesium compounds such as cesium carbonate, or cesium sulfate, or cesium hydroxide or their mixtures thereof and the mixture is roasted in air or oxygen at high temperature inside a kiln. After cooling, the solid sintered mass containing cesium tungstate is leached or dissolved with water or heavy water for producing dense aqueous solutions or deuterated solutions of cesium tungstate.
