LANGASITE-TYPE OXIDE MATERIAL, METHOD FOR PRODUCING SAME, AND RAW MATERIAL USED IN THE PRODUCTION METHOD |
摘要 |
An oxide material having a langasite-type structure having a desired surface condition and a desired outer shape is obtained stably. By adding at least one selected from the group consisting of Ir, Pt, Au, and Rh to a raw material which is a composition used for producing a desired oxide material as an additive element, it is possible to control the wettability between a die portion at a bottom end of a crucible and a melt of the raw material, thereby implementing stable production of the oxide material while controlling the wetting and spread of the melt of the raw material leaked out through a hole of the crucible.
