Abstract: Dicalcium phosphate anhydride powder of which at least 50% by weight is of a grain size of between 45 and 150 ?m, a maximum of 50% by weight is of a grain size of <45 ?m and a maximum of 5% by weight is of a grain size >150 ?m and which has a bulk density of between 1000 and 1500 g/l and a specific surface area of <5 m2/g is used for direct tabletting or capsule filling of pharmaceutical preparations.

Abstract: A laser-writable molding material containing A) at least one polymer material or at least one precursor compound which can be polymerised to give a polymer material, and B) a particulate salt-like compound or a mixture of particulate salt-like compounds, which under the influence of laser light changes its color or leads to a color change in the component A). In order to enlarge the range of matrix materials hitherto available for laser writing and to overcome the disadvantages of the previously used writing procedures for such matrix materials, the laser-writable molding material according to the invention is characterised in that the at least one polymer material of the component A) is selected from polymer compounds having siloxane crosslinking units.

Abstract: A process for the production of nanofine metal phosphates including the steps of: preparing a solution containing metal cations, phosphate anions and organic carboxylic acid, and finely spraying the solution in a reactor at a temperature above 100 degrees C. wherein the temperature is selected to vaporize the organic acid, and water if present, to obtain nanofine metal phosphate particles.

Abstract: The invention relates to dicalcium phosphate anhydride powder, at least 50 wt. % thereof having a particle size of between 45 and 150 ?m, a maximum of 50 wt. % having a particle size of <45 ?m, and a maximum of 5 wt. % having a particle size of >150 ?m. Said powder also exhibits a bulk density of 1000 to 5000 g/l and a specific surface area of <5 m2/g, and is used to directly tablet or encapsulate pharmaceutical preparations.
