colloidal titanium dioxide manufacturer

titanium oxide and 2 per cent' sulphuric acidand 63 per cent water, are slowly added to a solution containing 1050 pounds of barium sulphide, held in a large cylindrical tank, provided with a rotary agitation :capable of producing rapid agitation. The mass isthus v rapidly agitated, and the 2 per cent of sulphuric acid contained in the titanium acid cake reacts with a small portion of the barium sulphide. This reaction may be represented by the following equation TiO H 80 The free sulphuric acid of the titanium acid cake is neutralized by thebarium sul-' phide solution, forming barium sulphate and hydrogen sulphide, as indicated by the above equation. As the sulphuric acid is present only in a small percentage, the major porltiion of the barium sulphide remains as suc very fine colloidal suspension. The barium sulphate produced is also very fine, and the presence of this. very fine barium sulphate in suspension, and also of the very fine colloidal titanium oxide, is believed to be the explanation of the great improvement in the properties of the finished lithopone.

The process described is seen to consist of preparing separate solutions of readily-soluble salts of zinc and barium together with a third salt, which will further the reaction and at the same time upon uniting the solutions produce by one set of combinations lithopone and a marketable byproduct. This process, moreover, insures the greatest purity of the substances produced and avoids the expense attendant upon more difficult methods in common use. Thisis particularly true with respect to the manufacture of various grades of lithopone, since by properly calculating the amounts of the ingredients used, as above illustrated, any desired quality of lithopone may be produced without mixing additional substances to increase or decrease the percentage of zinc sulfid. The entire product, too, is an absolutely uniform mixture when prepared in accordance with my process.

  • In conclusion, China's foray into the medical application of titanium dioxide is a testament to the nation's innovative spirit and scientific prowess. As research continues to unfold, TiO2 promises to revolutionize the way we approach disease treatment and prevention, marking a new era in the intersection of materials science and medicine.
  • R5566 is a versatile rutile titanium dioxide that finds applications in a wide range of industries, including cosmetics, textiles, and ceramics. Its superior whiteness and brightness make it a preferred choice for achieving impeccable finishes in various products. R5566 also offers good UV resistance, making it suitable for use in outdoor applications where exposure to sunlight is a concern.
  • Furthermore, the use of R960 in TiO2 manufacturing also leads to environmental benefits. The catalyst systems that incorporate R960 generate significantly less waste and emissions compared to traditional methods, reducing the environmental footprint of TiO2 production.
