Latest Patents

Gunter Buttner holds a patent for a "Process for the preparation of alloy powders which can be sintered." This process involves the calciothermal reduction of metal oxides in the presence of neutral additives. The method includes mixing titanium dioxide (TiO₂) with other metal oxides, adding an alkaline earth oxide or carbonate, and calcining the mixture. After cooling, the mixture is crushed, and calcium is added. The resulting green compacts are then heated and leached to remove calcium oxide. The final powder exhibits a uniform structure, is free of segregations of oxides, nitrides, carbides, and/or hydrides, and possesses high bulk and tap densities, making it suitable for isostatic hot molding.
