The present invention is a composite powder having finely structured particles that can be obtained by a method in which large particles are combined with small particles, wherein the large particles have an average particle size in the range of 10 μm to 10 mm, At least one polymer, the small particles are disposed on the surface of the large particles and / or distributed heterogeneously within the large particles, the small particles include a calcium salt, and the small particles are 0 0.01 μm to 1.0 mm in average particle size, the composite powder particles have an average particle size d 50 in the range of 10 μm to less than 200 μm, and the fine particle fraction of the composite powder is less than 50% by volume It is related with the composite powder which is. Preferred application areas of the composite powder include additives, in particular polymer additions, for compounding, for the production of components, for applications in medical and / or microfabrication techniques and / or for the production of foamed articles. Its use as an agent, mixture or starting material is included. Thus, the present invention further excludes implants for application in the fields of neurological surgery, mouth, jaw, face, throat, nose and ear surgery, and hand, foot, chest, rib and shoulder surgery. The invention relates to a component obtainable by selective laser sintering of a composition comprising a composite powder according to the invention. |
