| titleOfInvention | Composite powder containing calcium carbonate and having microstructured particles |
| abstract | The invention relates to a composite powder having microstructured particles, obtainable by a method wherein large particles are connected to small particles, wherein the large particles have an average particle diameter in the range from 0.1 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 inhomogeneously distributed within the large particles, the small particles comprise spherical precipitated calcium carbonate particles having an average diameter in the range from 0.05 μm to 50.0 μm, wherein the spherical calcium carbonate particles are obtainable by a method wherein a. a calcium hydroxide suspension is provided, b. carbon dioxide or a gas mixture containing carbon dioxide is introduced into the suspension from step a. and c. occurring calcium carbonate particles are separated, wherein 0.3 wt% to 0.7 wt% of at least one aminotrialkylene phosphonic acid is furthermore added. Preferred application areas of the composite powder comprise the use thereof as an additive, in particular as a polymer additive, as an additive material or starting material for compounding, for the production of components, for applications in medical technology and/or in microtechnology and/or for the production of foamed objects. The invention thus further relates to components which are obtainable by selective laser sintering of a composition, comprising a composite powder according to the invention, except implants for applications in the fields of neurosurgery, oral surgery, maxillofacial surgery, neck surgery, nasal and ear surgery, and hand, foot, thoracic, rib, and shoulder surgery. The invention further relates to the spherical calcium carbonate particles that can be advantageously used for producing the composite particles according to the invention, and to the use thereof. |
