PROCESS FOR PRODUCING ALUMINUM NITRIDE CRYSTAL AND ALUMINUM NITRIDE CRYSTAL OBTAINED THEREBY

摘要

A process in which an aluminum nitride crystal can be produced under moderate pressure and temperature conditions. There is provided a process for producing an aluminum nitride crystal, comprising forming and growing of an aluminum nitride crystal through reaction, in the presence of a nitrogenous gas, of the nitrogen with aluminum in a flux containing the following components (A) and (B) or in a flux containing the following component (B): (A): element(s) of at least either an alkali metal or an alkaline earth metal group, and (B): at least one element selected from the group consisting of tin (Sn), gallium (Ga), indium (In), bismuth (Bi) and mercury (Hg).
