AI Technical Summary
Technical Problem
The oxide powder obtained by synthesizing oxide powder will still retain some carbon and hydroxyl groups, and the energy consumption will be large during calcination.
Method used
A production device is designed, including a shell and a heating structure, by flowing the oxide precursor into the receiving chamber and heating it during the flow process, alcohols and water are removed to form a stable oxide structure, reducing the time for subsequent drying and calcining, and reducing energy consumption.
Benefits of technology
High purity production of oxide powder is achieved, reducing carbon and hydroxyl residues, reducing energy consumption and improving production efficiency.

Abstract
The present invention relates to the technical field of oxide powder preparation, and discloses a production device, a production method and oxide powder. The production device comprises: a shell having a containing cavity, a first liquid inlet and a liquid outlet being arranged on the shell, the first liquid inlet being used to introduce an oxide precursor; a heating structure being used to heat the oxide precursor to remove alcohol substances and water in the oxide precursor. The oxide gel prepared by the present invention using an oxide precursor has a metal impurity content of less than 500 ppb and high purity; the oxide precursor is flowed into the containing cavity from the first liquid inlet and flows out from the liquid outlet, and alcohol substances and water with lower boiling points in the oxide precursor can be evaporated during the flow process, and a condensation reaction occurs inside the oxide precursor during the heating process to form a stable oxide structure, thereby removing carbon and hydroxyl groups in the oxide precursor, reducing the time for drying and calcining the oxide gel, and reducing energy consumption in the oxide powder production process.
