Title:
HEAT-RESISTANT BLACK POWDER, METHOD FOR PRODUCING SAME, AND PAINT AND RESIN COMPOSITION USING HEAT-RESISTANT BLACK POWDER
Document Type and Number:
WIPO Patent Application WO/2012/133646
Kind Code:
A1
Abstract:
The invention provides a heat-resistant black powder that is ideal as a paint or resin composition because heat resistance is excellent and there is little change in color (degree of black) even under a high temperature. The heat-resistant black powder is formed from a compound oxide comprising Fe, Mn, and metal element M (where M is one or more selected from Al, Mg, and Ca). The change in color in heat resistance testing at 800ºC is 0.5 or less and the magnetization value is 2.0 Am2/kg or less. The heat-resistant black powder is a heat-resistant black powder formed from a hematite phase and a bixbite phase. The heat-resistant black powder can be obtained by mixing an iron compound, a manganese compound, and a metal element M compound and baking the resulting mixture at a temperature range of 830 to 1,000ºC.
