Abstract:
1. A method to produce biologically active glass powder comprising the following steps: producing a glass melt from a predefined volume of glass; forming a plurality of particles from said glass melt by atomizing, said plurality of particles including a plurality of non-spherical particles individual ones of which have a ratio of length to diameter of 1.1 to 10 atomizing said glass melt in an atomizer apparatus to which said glass melt is supplied and which includes a first nozzle device and a second nozzle device which are located in tandem in a flow direction of said glass melt stream of said glass melt, at least one primary gas flow being admitted using said first nozzle device which discharges parallel to said glass melt stream in an area of entry of said glass melt stream into said atomizer apparatus and which guides said glass melt stream, a second gas flow being admitted for atomizing using a second nozzle device at an angle upon said glass melt stream, said second gas flow being admitted uniformly in a circumferential direction of said glass melt using said second nozzle device; heating a gas which is to be supplied through said first and said second nozzle devices to a temperature of between 293 and 1300K; and admitting said gas which is to be supplied through said first and said second nozzle devices into said atomizer apparatus at a pressure of between 0.1 and 0.6 MPa.
