Alumina composite, method for manufacturing alumina composite, and polymer composition containing alumina composite |
摘要 |
For the purpose of producing an alumina composite in which the integrity between alumina and an inorganic material is further improved, a dispersion liquid preparation step, a solidification step and a burning step are performed, wherein the dispersion liquid preparation step comprises preparing a dispersion liquid in which an inorganic material such as a carbon material is homogeneously dispersed in an alumina raw material solution having an organic additive dissolved therein, the solidification step comprises drying the dispersion liquid to produce a solid raw material, and burning step comprises burning the solid raw material in a non-acidic atmosphere while contacting hydrogen chloride with the solid raw material. In this manner, an alumina composite can be produced, in which at least a portion of an inorganic material such as a carbon material is embedded in the inside of each of α-alumina single crystal particles the constitute alumina particles. |
