[0087] Hereinafter, examples of the present invention will be described, but the examples are for the purpose of illustration and are not intended to limit the invention.
[0088] (Verification of the effect by the first roasting)
[0089] Crude rhenium sulfide having the analytical values described in Table 1 was prepared. The content rate of each component was measured by chemical analysis (analyzed by ICP-OES.).
[0090] 【Table 1】
[0091]
[0092] For 500 g of the crude rhenium sulfide, the first firing was carried out for 120 to 140 minutes under various furnace atmosphere temperature conditions, and then the furnace was cooled to room temperature. A kiln is used as the roasting furnace, and air is used as the oxygen-containing gas. In any case, the oxygen equivalent was in the range of 1.9 to 2.2. In addition, it can be seen that when the air is preheated to a predetermined temperature (here, 140° C.) and supplied to the kiln, the temperature of the atmosphere i...
