Title:
METHOD FOR PRODUCING INORGANIC OXIDE PARTICLES
Document Type and Number:
Japanese Patent JP2023036471
Kind Code:
A
Abstract:
To provide a method for producing spherical inorganic particles which contain no carbon impurities and has no problems of insulation properties and electricity resistance when used as an inorganic filler for a sealing material.SOLUTION: There is provided a method for producing spherical inorganic particles which comprises a supply step of supplying raw material particles into a flame formed from a mixed gas containing hydrogen and oxygen and having a mixed ratio of a hydrocarbon gas of 10 ppm or less. There are used particles which contain a metal element constituting inorganic oxide particles in the state of a single metal or a semimetal element constituting inorganic oxide particles in a semimetal state as raw material particles and have a carbon atom content of 0.01 mass% or less relative to raw material particles and an average particle diameter of 1 μm or more and 100 μm or less.SELECTED DRAWING: None
