In order to provide a hydroxyapatite that can be used without reservation in the food industry, a hydroxyapatite powder is provided composed of primary particles. The median size of the primary particles from which the powder is made is >0.10 μm and the aspect ratio of the primary particles is <5. The specific surface area of the hydroxyapatite powder is ≤10 m/g, and the bulk density is >550 g/l. Also disclosed is a method with which such a hydroxyapatite powder can be obtained.

Hydroxyapatite powder and method for producing same

The present invention relates to a method for producing a phosphate-containing anti-corrosive pigment, to the phosphate-containing anti-corrosive pigment obtainable by this method, and to the use of the phosphate-containing anti-corrosive pigment for passive protection against corrosion.

Phosphate-containing anti-corrosive pigment

A method for manufacturing electrically conductive structures, preferably conductive pathway structures using laser beams on a non-conductive carrier (LDS method), wherein a non-conductive carrier material is provided which contains at least one inorganic metal phosphate compound and at least one stabiliser finely distributed or dissolved therein, the carrier material is irradiated in regions by laser beams generating the electrically conductive structures in the irradiated regions.

Method for manufacturing electrically conductive structures on a carrier material

A method of using an absorber of electromagnetic radiation, includes absorbing electromagnetic radiation with the absorber finely distributed or dissolved in a carrier material. The absorber is a crystal water-free iron(II) orthophosphate of the general formula Fe(PO)or crystal water-free iron(II) metal orthophosphate, iron(II) metal phosphonate, iron(II) metal pyrophosphate or iron(II) metal metaphosphate of the general formula FeMet(PO), where a is a number from 1 to 5, b is a number from &#x3e;0 to 5, c is a number from 2.5 to 5, d is a number from 0.5 to 3 and Met represents one or more metals selected from the group consisting of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, the transition metals (d block), the metals and semimetals of the third, fourth and fifth main groups, and the lanthanoids or combinations of the above mentioned phosphates as absorbers of electromagnetic radiation.
