摘要： The invention relates to a method for the further processing of iron sulfate heptahydrate into iron sulfate monohydrate. An aqueous solution or suspension of iron sulfate heptahydrate is formed and heated in a pressure vessel to a temperature above its boiling temperature at atmospheric pressure and where solid iron sulfate monohydrate and a solution are formed. The solid iron sulfate monohydrate is separated from the solution and fed into a pressure vessel at a temperature above the boiling temperature of the solution at the pressure in the pressure vessel, which is lower than the pressure during separation.

摘要： A construction material mixture used as a concrete additive contains a puzzolanic substrate and a photocatalyst. The puzzolanic substrate and the photocatalyst are available in the form of a dry mixture. The construction material mixture is a cement free dry mixture, wherein the photocatalyst has a primary particle size of between 2 nm and 100 nm. The puzzolanic substrate consists of at least 90 weight % of fly ash with a grain size of between 0.1 μm and 1 mm. The substrate and the photocatalyst are available completely mixed so that the photocatalyst is at least partially distributed on the surface of the substrate.

摘要： The invention relates to a stable, highly concentrated, aqueous suspension of nanoparticles, particularly of titanium dioxide particles, a method for production, and use of the suspension, e.g. for coating or impregnation, or as an additive in organic or inorganic matrices. The suspension contains a first dispersant based on a polymeric alkoxylate and a second dispersant selected from the group of amino alcohols. The suspension is preferably characterized by the fact that its stability is preserved even during and after vigorous dispersion in an attrition mill and no increase in viscosity occurs. In a preferred embodiment, the viscosity declines by up to 10 to 50% as a function of the milling time. In a further embodiment, the suspension can be dried and subsequently redispersed, without the state of dispersion deteriorating.

摘要： The manufacture of titanium dioxide by oxidation of titanium tetrachloride in a multistage method, where both oxygen and titanium tetrachloride are added in several stages. In the first stage gaseous TiCl4 is introduced into a preheated oxygen-containing gaseous stream in a stoichiometric or hyper-stoichiometric amount to produce a TiO2 containing gas suspension. In the second or further stages liquid TiCl4 and oxygen-containing gas is introduced into the TiO2 containing gas suspension to produce further TiO2.

摘要： A method of predicting photostability of coatings with various dopants on titanium dioxide pigment particles is disclosed. Calculations of the density of states show that a doped coating which reduces the density of states near the band edge or increases the density of states within the band gap of the pigment particles increases the photostability of the doped pigment.
