Title: Alumina particle material and production method of the same
Inventor: NAKAMURA NOBUHO
IPC: C01F7/02
Filed: 2020-02-21
Abstract: To provide a production method of an alumina particle material, with which a particle material can be phase-transferred to an α-phase while suppressing change of the shape.SOLUTION: A method to α-convert a particle material while mostly maintaining sphericity is disclosed. The method is completed by finding that when the speed of advance of α-conversion is equal to or larger than a specified value, the particle material is deformed and sphericity is deteriorated. For suppressing advance of α-conversion, (i) a method to lower heating temperature, and (ii) a method to use a silicon-containing compound which reduces the speed of advance of α-conversion are found to be effective. In the method to lower heating temperature (i), as it has been made apparent that α-conversion does not advance in a state of a low content of the α-phase by simply lowering the temperature, temperature is lowered after a portion of the particle material has been α-converted initially, and thereby α-conversion has advanced slowly thereafter. In the method (ii), the speed of advance of α-conversion can be suitably controlled by suitably controlling the content of the silicon-containing compound.SELECTED DRAWING: Figure 2
