lithopone and titanium dioxide manufacturer

  • The titanium pigment market overview todayFinished as of today, sulfuric acid method of rutile type titanium pigment market assessment for an average of 15983 yuan/ton, the domestic market mainstream negotiations reference in 15500-16700 yuan/ton, titanium dioxide upstream raw material prices strong, mainstream factory inventories low, a new single strike price.According to the manufacturer feedback, recent mainstream factory new single pretty price, clinch a deal market as a whole center of gravity move up. Demand side, the current most downstream have early ready for the order, but for the sake of subsequent order, the current new single talks enthusiasm strong; Supply side, some manufacturers actual load current, titanium white production output increase gradually, but the real single link part model in the tight delivery situation is still there. Part of the plastic and paper related downstream feedback some models price is higher. Recent titanium pigment raw material prices strong, titanium white price support increased, the comprehensive market all factors, the current general market price upward of titanium white new single single talk.To distinguish the downstream areas, such as plastic and paper related model compared with good market demand associated with coating model, supply chain, special class output are relatively limited, manufacturers perform a slightly higher price, plastic and paper such as some models price is in 16700 yuan/tons.

    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.

    Lithopone, C.I. Pigment White 5, is a mixture of inorganic compounds, widely used as a white pigment powder. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide (zinc white), zinc sulfide, and white lead.[1]
