Product details
Calcium tungstate is an important chemical substance with a wide range of applications.
Firstly, compared with rare-earth phosphors, calcium tungstate can reduce the time a patient is exposed to X-rays, improve the resolution of X-rays, extend the life of X-ray tubes and reduce energy consumption.
Secondly, calcium tungstate can be used to produce lithium niobate single crystals and can be used at high temperatures of 1850°C.
In addition, common tungstates include sodium tungstate, cobalt tungstate and cadmium tungstate, in addition to bismuth tungstate, which are widely used in the fields of chemical industry and optoelectronics due to their good physical and chemical properties.
In conclusion, calcium tungstate has important applications in medical, chemical, electronic and electrical industries.
Uses and Function of Calcium tungstate.
Calcium tungstate is an important chemical raw material, mainly used in the production of tungsten products such as ammonium sec-tungstate, tungsten trioxide, ferro-tungsten, alloy steel, tungsten carbide, tungsten material, tungsten wire and tungsten alloy.
It can be used in fluorescent coatings, photographic light screen tubes, medicine, X-ray photographs and fluorescent lamps.
In addition, calcium tungstate is a very effective luminescent material under X-ray, electron beam and ultraviolet excitation, and can emit blue fluorescence.
Characteristic of Calcium tungstate.
Product Methods of Bulk Calcium tungstate Powder.
Calcium tungstate is produced by reacting calcium oxide or calcium hydroxide with tungsten oxide or tungsten hydroxide in alkali metal hydroxide or carbonate solutions.
Sodium tungstate is mixed with sodium sulfide and dissolved with water, then aqueous zinc chloride is added, filtered, and the filtrate is treated with pure calcium chloride to produce calcium tungstate.
