Fabrication of Pyrophyllite Granule Powders for Thermal Spray Coating

摘要

The present invention provides a method of manufacturing agalmatolite granule powder for spray coating, comprising: a step of mixing natural agalmatolite powder with a solvent and adding a dispersant to manufacture slurry; a step of pulverizing the agalmatolite powder into an average grain size having a range of 1-4 m; a step of spraying and drying the slurry to manufacture the agalmatolite granule powder; and a step of performing heat treatment on the agalmatolite granule powder. Accordingly, the present invention enables ceramic granule powder for spray coating to be manufactured, capable of universally being used using agalmatolite minerals of a level of 45 m being price competitiveness.
