Anatase titanium dioxide synthesis of some of the elaborate

 Divided titanium dioxide anatase and rutile titanium dioxide two categories, but their production and synthesis method is not the same? Of course, is not the same, different titanium dioxide has a different production technology and production formula , and now we look anatase titanium dioxide synthesis methods and production processes it.
1 , the use of leaching firing . Containing 95% or more of natural barium oxide and anthracite 3:01 ( mass ) mixed plastic processing aid  feed barium sulfate , crushed to a diameter of about 2 cm below the reduction furnace , oven temperature control before 1000 1200 ℃ after the first 500? 600 ℃ , 80 , in turn reducing the speed of the furnace , the reaction conversion rate of 80% ? 90% of the sulfide obtained in the rotating extractor , the temperature control to 65 ℃ above , barium , barium sulfide content is 701 % and further refinement of the cylinder of zinc sulfate was added to clarify the reaction , zinc sulfate content of more than 28 % of the  lead stearate control , pH value of 8-9 , and the resulting mixture of barium sulfate and zinc sulfide has a density of 1.296 ? 1.357 g ╱ cc . Frame after pressing , the reaction mixture was filtered to obtain a cake , such as anatase type titanium dioxide , the water content of not more than 45 %, thus changing the crystal was dried calcined calcined anatase titania, and 80 ℃, temperature , using sulfuric acid. Finally wash, enhanced toner, pressure filtration, drying and grinding. 2, the prepared solution , barium sulfide , barite firing . Compressed zinc sulfate solution, the reaction with sulfuric acid and zinc oxide , po PVC stabilizer for wire  prepared by the metathesis reaction , to obtain a mixture of zinc sulfide and barium sulfate precipitation, and the precipitate was filtered under pressure , calcination, wet milling , drying, crushing , lithopone to be finished. He BAS zinc sulfide barium sulfate →
3, with the right system common titanium dioxide calcined product obtained by beating to , washed successively with sodium silicate , sodium aluminum sulfate or aluminum and a surface active agent for surface treatment , and then filtered , washed with water , dried , possibly .
