A method for producing surface-treated particles includes surface treatment of titanium dioxide, barium sulfate, zinc sulfide or lithopone particles, and to mixtures of the particles with alkoxylated siloxanes and phthalate-free plasticizers for improving dispersion in plastics.

Method for treating the surface of particles, the thus obtained particles and use thereof

Surface treatment of titanium dioxide, barium sulfate, zinc sulfide, and/or lithopone particles, and mixtures of said particles with specific alkoxylated siloxanes for the improvement of dispersion in plastics.

Surface treatment of particles and their use

A TiO2-based catalyst material in particle form having a content of metal removes pollutants, in particular of nitrogen oxides from combustion gases.

Catalyst material and process for the production thereof

The invention concerns a process for the production of a storage-stable barium sulphate, the barium sulphate produced thereby and the use thereof as an additive.

Process for the production of a storage-stable barium sulphate having good dispersibility

A method of making a powder coating composition includes obtaining functionalized particles by reacting inorganic particles with alkoxysilanes having the general structural formula (I) RSi(OR), silane oligomers having the general structural formula (II) (R)(OR)Si&#x2014;O&#x2014;[&#x2014;Si(R)(OR)&#x2014;O&#x2014;]&#x2014;Si(R)(OR)or mixtures thereof.

Functionalized particles and use thereof

A particulate porous spherical titanium dioxide has a TiOcontent of at least 99.0% by weight, a particle size din the range of 30 to 350 &#x3bc;m, a tight particle size distribution (B 90/10) in the region of a maximum of 120 &#x3bc;m, a pore diameter of 1 to 30 nm, a pore volume of at least 0.1 cm/g, and a surface area of 30 to 300 m/g (BET).

Porous spherical titanium dioxide

The invention concerns a process for preparing an additive for polymers, the additive itself and the use of the additive for improving the surface properties of polymers.
