Application
Titanium phosphate, as a novel inorganic chemical product, can be used as a pigment and filler in industries such as coatings, plastics, rubber, and papermaking. Titanium phosphate can complex metal ions with large radii and can also be used as a water treatment agent.
Synthesis
Weigh a certain amount of titanium dioxide waste acid into five flasks, and then heated to 80 with a heating jacket, with a peristaltic pump into the mass concentration of 5% (NH4) 2HPO4 solution, 5 minutes to play, titanium dioxide in the titanium dioxide waste acid mass and diammonium hydrogen phosphate mass ratio of 1:2.5, fully mixed and stirred, hold for 5 minutes, a little bit cooled, filtered, washed with 200 ml of demineralized water for 1 time, then Analyze the titanium content in the filtrate, and put the filter residue into the constant temperature oven at 105oC to keep warm for 2 hours;
Finally, the dried filter residue is finely ground and put into the crucible for calcination, the calcination temperature is 800, and the calcination time is 2 hours, and that is to get the titanium phosphate product.
