Title:
微細構造粒子を有するカルシウム塩含有複合粉末
Document Type and Number:
Japanese Patent JP6968887
Kind Code:
B2
Abstract:
A composite powder containing microstructured particles obtainable by means of a method in which large particles are combined with small particles, whereinthe large particles have an average particle diameter within the range from 10 μm to 10 mm,the large particles comprise at least one polymer,the small particles are arranged on the surface of the large particles and/or distributed inhomogeneously within the large particles,the small particles comprise a calcium salt,the small particles have an average particle size within the range from 0.01 μm to 1.0 mm,wherein the particles of the composite powder have an average particle size d50 within the range from 10 μm to less than 200 μm, and the fine-particle fraction of the composite powder is less than 50% by volume.Preferred application areas of the composite powder encompass its use as additive, especially as polymer additive, as additive substance or starting material for compounding, for compounding, for the production of components, for applications in medical technology and/or in microtechnology and/or for the production of foamed articles.The invention therefore also provides components obtainable by selective laser sintering of a composition comprising a composite powder according to the invention, except for implants for uses in the field of neurosurgery, oral surgery, jaw surgery, facial surgery, neck surgery, nose surgery and ear surgery as well as hand surgery, foot surgery, thorax surgery, rib surgery and shoulder surgery.
