Abstract
PURPOSE: Mg and Al are passed through different passages in reactor and heated to a predetermined temperature, thereby to grow desired magnespinel on substrate without contaminating Al source.
CONSTITUTION: A tray 5b holds Mg 6b and a tray 5c holds Al 6c respectively. A lower hollow portion 2c holding Al has a length l2, preferably 1.5 to 2 times lenght l1 of an upper hollow portion 2b holding Mg. If l2 is shorter than this length, effective prevention of Al contamination is not achieved. Al is heated to 500 to 600°C by a heating means 7b and Mg is heated to 600 to 900°C by a heating means 7c. Mg is contacted with HCl gas. Carrier gas from an inlet port 8 mixes with reactive of Al and Mg and advances toward magnespinel substrates 10 which are heated to 1000 to 1300°C to effect growing of magnespinel single crystal to a desired thickness.
