发明名称 Particulate aluminum nitride and method for producing thereof
摘要 A method for producing aluminum nitride includes preparing a slurry containing pseudoboemite and carbon, filtrating and dehydrating the slurry to form a precursor, and calcinating the obtained precursor in an atmosphere containing nitrogen. The slurry is prepared by dispersing a carbon powder in an aqueous solution having a pH adjusted in a range of 8.5 to 9.5, and then synthesizing pseudoboemite by using at least one of an aluminum salt and aluminic acid as an aluminum source, while maintaining the pH of the reaction mixture in a range of 8.5 to 9.5. The aluminum nitrite obtained by the method has a three-dimensional network structure and thus exhibits excellent heat-conducting property and can be suitably used as a filler for an electronic material.
