摘要： PURPOSE:To shorten production time as well as to control grain size by supercooling rate. CONSTITUTION:In this production method, a seed crystal is put on the surface of a precursor of a Y-contg. oxide superconductor, the precursor is heated to a half-melted state and supercooled to a solidifying region and then crystal growth is carried out. The precursor is obtd. by mixing powdery starting materials in a prescribed ratio, calcining the mixture and compacting the resulting calcined powder. The half-melted state is attained by heating to 1,000-1,200 deg.C and the supercooling rate is carried out in the range of >0 deg.C to 100 deg.C.

摘要： PURPOSE:To obtain a coarse crystal with a simple process by calcining a mixture of raw materials having a specified composition under specified conditions, crushing the calcined material to obtain a precursor, forming the precursor, rapidly heating and then slowly cooling the formed body. CONSTITUTION:The mixture of raw materials having a specified composition is heated at 800-1000 deg.C for 1 hr in the low-oxygen-partial-pressure atmosphere with the oxygen partial pressure controlled to Torr, and the calcined material is crushed to obtain a precursor. The precursor is formed, rapidly heated to the temp. range where a 211 phase and a liq. phase coexist and then slowly cooled to grow the crystal.

摘要： PURPOSE:To continuously prepare a large oxide crystal or a crystal having a Y-based 123 structure. CONSTITUTION:A liquid phase, enclosing a solid phase having a composition which supplies a crystal constituent element to a liquid phase 3 and is different from an oxide crystal in a place distant from a position for growing the crystal, composed of at least the crystal constituent element and having the composition different from the oxide crystal is used for growing the oxide crystal. Thereby, the crystal having the different compositions is grown from the solid and liquid phases. Furthermore, a seed crystal, the rotational speed and rotative direction of the seed crystal and the atmosphere in a furnace are respectively controlled to grow the crystal having the different compositions from both the solid and the liquid phases.
