| titleOfInvention | Manufacturing method of aluminum nitride |
| abstract | (57) [Problem] To produce α-alumina by using γ-alumina containing magnesium as a raw material so that γ-alumina undergoes only an AlN conversion reaction without causing AlN conversion. It is intended to obtain only AlN without fail. SUMMARY OF THE INVENTION A magnesium compound obtained by mixing an aqueous solution obtained by adding a water-soluble organic or inorganic aluminum compound and a water-soluble organic or inorganic magnesium compound to water, drying and calcining the mixture. Is contained in a mixed gas of a hydrocarbon gas containing 0.5% by volume or more of a hydrocarbon gas and an ammonia gas. The aluminum nitride is manufactured by heat treatment at 700 ° C., and then the obtained aluminum nitride is heated to 1600 to 600 g in an inert gas, ammonia gas, or a mixed gas of ammonia gas and inert gas. It is characterized by heating at 2000 ° C. |
