For example, a melting crucible of a melting apparatus for melting a metal or glass at a melting temperature of about 600 to 2000 ° C. was manufactured by the joining technique. In this case, when the entire crucible is thermally expanded by high-temperature heat up to about 600 to 2000 ° C., a tensile stress is applied to its peripheral wall and the joint between the peripheral wall and the bottom wall, and there is a risk that the joint will peel off due to a thermal shock received from high-temperature heat. There is a disadvantage inferior in strength such as there is, 600-2000 ℃
At present, it is poorly practical at high temperatures, and no measures have been taken for strength at high temperatures.
