Latest Patents
One of Irie's latest patents is a process for producing metal powders. This innovative method involves a chlorination step that continuously produces chloride gas of metal by reacting metal with chlorine gas. Following this, a reduction step is employed to continuously reduce the metallic chloride gas by reacting it with a reducing gas. By regulating the feed rate of chlorine gas, the particle diameters of the produced metal powders can be stably controlled within a range of 0.1 to 1.0 µm. This invention allows for the stable and arbitrary control of particle diameters, which is crucial for various applications.
Another significant patent by Irie is a method for producing titanium alloy. This method utilizes the reduction of titanium tetrachloride and alloy components with a reducing metal agent. It is capable of continuously producing titanium alloy on an industrial scale. The reaction zone's temperature and pressure are maintained above the melting point of the titanium alloy, ensuring that the reducing metal agent and its chloride remain in a molten state without boiling.
