Abstract: The invention relates to a process for the preparation of a resorptive bone ceramic on the basis of tricalcium phosphate which can be used as a bone replacement material. In the process, natural bone material, freed from the soft tissues, is used as the starting material. The remaining organic substances are removed from this starting material by pyrolysis. The remaining bone material, which consists virtually completely of hydroxyapatite, is subsequently treated with a phosphate carrier and then subjected to a sintering step.

Abstract: According to a process for producing a bone replacement material, natural bones are used as raw material, the soft parts of the bones are removed, as well as any residual organic substances, and the remaining osseous substance is finally sintered at temperatures between 1100 degrees and 1500 degrees Celcius. In order to simplify such a process and to ensure a more gentle processing of the inorganic bone matrix, the bones are dried at an increased temperature, maximum 550 degrees Celcius, with a reduced air supply or in a reducing atmosphere, then the temperature of the bones is increased during the following step up to 750 degrees to 800 degrees Celcius, with an increased air supply, and finally the bones are sintered.

Abstract: An extraction valve head for a tank for high-purity and/or toxic liquid chemicals has an inlet valve for a filler gas, an outlet valve and a purging valve, which closes a bypass between a gas inlet line and an extraction line. The valves are configured as metal diaphragm valves and are fitted in a common metallic valve housing block. All valve seals of the valves are arranged in close spatial proximity to one another in the valve housing block.
