摘要：PURPOSE:To easily obtain a Tl-bad oxide superconductor which is little in fluctuation of composition and free from the impurities and has a single pha by supplying Tl vapor together with oxygen and fetching Tl into a sintered body in the ca of calcining the raw material of an oxide superconductor contg. Tl to form a sintered body. CONSTITUTION:Both a vesl 13 housing a raw material 14 of a superconductor and a vesl 15 housing powder 16 (e.g. Tl oxide) contg. Tl are arranged in a furnace core pipe 12 inrted into a sintering furnace 11. While gaous oxygen is supplied into the furnace core pipe 12 from an introduction pipe 19, this core pipe 12 is heated. The raw material 14 is calcined to form a sintered body and also Tl vapor is generated from the powder 16 contg. Tl. Tl vapor is supplied to the raw material 14 together with oxygen. Thereby vaporization of Tl from the raw material 14 can be inhibited and also Tl is fetched into the sintered body. A Tl-bad oxide superconductor having the aimed composition ratio is produced.
