The invention relates to an Incineration apparatus, comprising a fluidized bed redox reactor (2) having—a reaction chamber (8) with particulate matter and—a fluidized bottom with at least one reducing agent inlet (9) for a gas to fluidize the particulate matter.

The invention concerns pre-alloyed powders useful for the manufacture of metal-bonded diamond tools. A process for the synthesis of such powders is presented, characterized in that at least a major part of the phosphor is introduced by adding an aqueous solution of a phosphorus salt to one or more of the metal-bearing compounds. The powder can have a low cobalt content, or even be cobalt-free, yet remain suitable for the production of diamond-loaded segments having harness and bending characteristics approaching or exceeding that of cobalt.

Proposed is an iridium alloy catalyst having reversible catalytic activity for an oxygen evolution reaction (OER), a hydrogen evolution reaction (HER), and a hydrogen oxidation reaction (HOR) by including an iridium alloy including iridium (Ir) and nickel (Ni). The iridium alloy catalyst according to the present disclosure is rapidly converted to an iridium alloy catalyst in an oxide form and an iridium alloy catalyst in a metallic form according to applied voltage by controlling its crystallinity. Thus, even in case an oxide layer is formed after the OER, the oxidation layer disappears during the HER and HOR and the properties of an iridium metal catalyst remain, thereby maintaining HER/HOR performance.

The present invention discloses a method for refining large-particle-size pure copper or copper alloy particles by high-energy ball milling, the method comprising the following steps: (1) using large-particle-size pure copper or copper alloy coarse particles as a raw material and cyclohexane or water as a process control agent, and crushing and refining the particles by high-energy ball milling to obtain small-particle-size copper or copper alloy powder; and (2) decreasing an oxygen content in the powder obtained in step (1) in a reducing atmosphere to obtain pure copper or copper alloy powder. In the present invention, by improving the overall process flow of the preparation method and the parameter conditions of each process step, the method greatly decreases energy consumption compared with existing copper powder preparation techniques. In addition, the method features a simple process and low production costs.
