TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: Precipitation is carried out by combining at least 2 initial solutions, by introducing gas into an initial solution or by hydrothermal treatment of an initial solution. The total amount of additive(s) is not more than 40, preferably not more than 30 wt.%, with 0.01-40, especially 0.01-30 wt.% (II) with respect to the coated product. An organic additive (III), may also be used, in an amount of 0.01-60, preferably 0.01-40, especially 0.1-20 wt.%; with respect to the finished coated product. An antifoam may be used, preferably in amounts up to 10, especially 0.01-5 wt.%.Preferred Components: (I) are metal compounds (examples) selected from (hydr)oxides (of titanium (Ti), zinc (Zn), iron (Fe), magnesium, silicon (Si), aluminum (Al), zirconium), (hydrogen) carbonates (calcium (Ca), barium (Ba), lithium (Li), strontium (Sr) carbonates), sulfates (of Ba, Ca), sulfides (of Zn, cadmium, Fe, tin), (hydrogen) phosphates (Al, Ti and Si-Al phosphates and Al H phosphate), titanates (of Ba, Sr, Ca), synthetic compounds with hydrotalcite structure, zirconates, silicates, aluminates and vanadates. Other preferred (I) are antimony monoxide, chromium oxide, metal nitrates and halides, nickel (Ni) titanate, Li titanate, metal ferrites (e.g. Ba, manganese and Ni ferrites), mixed oxides with spinel structure (e.g. spinel green (Co,Ni,Zn)2TiO4, Zn-Fe brown ZnFe2O4), molybdates and borates. All (I) may be in undoped or doped form and individual compounds or mixtures.Preferred Products: The coated (I) has an average particle size d50 of 0.1-10, especially 0.2-5 micrometers; and average crystallite size less than 200 nm, preferably of 1-120, especially 1-80 nm.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Additives: Preferred (III) (examples) are carboxylic acids, (metal) soaps, alcohols (1,1,1-trimethylolpropane), pentaerythritol, neopentyl glycol, polyols (pentaerythritol ethoxylates), polyglycols (polyethylene glycol), polyethylene glycol ethers, organic esters (neopentyl glycol dibenzoate), silanes, siloxanes, silicone oils, sulfones, ketones, nitriles, sulfoxides, sulfonic acids and alkali and ammonium salts (toluenesulfonic acid, ammonium p-toluenesulfonate), organic amides R-CO-NR'R (polyhydroxycarbonamides) or R-SO-ONR'R, organic amines (triethanolamine), alkali or ammonium salts of organic phosphoric esters (alkylolammonium salts of acid phosphoric esters) and fatty acid esters or amides.    TECHNOLOGY FOCUS - POLYMERS - Preferred Additives: Preferred (II) are alkali metal or ammonium salts of organic acids (e.g. poly(meth)acrylic acids and (meth)acrylate copolymers), polyphosphates ((in)organic polyphosphates, potassium tetrapolyphosphate, poly(meth)acrylate phosphates, aliphatic polyether phosphates), general poly(meth)acrylates, polyethers, anionically modified polyethers, fatty alcohol polyglycol ethers, modified polyurethanes, nonionic modified fatty acid derivatives or anionic aliphatic esters.
