    Abstract: The invention relates to a method for producing a homogeneous mixture of hard material powders and binder metal powders without using grinding bodies, liquid grinding auxiliary agents and suspending media. According to the invention, the mixture components are mixed at close range while generating a high shearing collision velocity of the powder particles and are remotely mixed by rotating the mixing bed without resulting in a particle size reduction of the hard material powders.

    Abstract translation: 本发明涉及不使用研磨体，液体研磨辅助剂和悬浮介质来制造硬质材料粉末和粘结剂金属粉末的均匀混合物的方法。 根据本发明，混合物组分在近距离地混合，同时产生粉末颗粒的高剪切碰撞速度，并通过旋转混合床进行远程混合，而不会导致硬质材料粉末的粒径减小。

    Abstract: The invention concerns metal powder granulates comprising one or a plurality of the metals Co, Cu, Ni, W and Mo. The invention further concerns a method for the production of these granulates and the use thereof. The production method is characterized in that a metal compound comprising one or a plurality of the groups comprising oxides, hydroxides, carbonates, hydrogenocarbonates, oxalates, acetates, formiates with binder and optionally in addition between 40 and 80% solvent, relative to the solids content, is granulated as the starting component, and the granulates are thermally reduced in a hydrogen-containing gaseous atmosphere to form the metal powder granulates, the binder and the solvent, if used, being removed completely.
