Induction skull melting of oxides and glasses

verfasst von: Maxim Kudryash, Torge Behrens, Bernard Nacke
Abstract: A multi-functional installation for induction skull melting of oxides is described. The installation allows realizing wide range of processes like synthesis of high purity oxide materials, single crystal growing, investigation of phase diagrams, melting of glasses and ceramics. Melting of low conductive oxide materials by high frequency electromagnetic field provides overheating the melt on 500 K and higher above the melting point with extremely low pollution of the material. A high frequency transistor generator accomplishes the installation. One inductor-crucible and two cold crucibles of various volumes were used for the research. Melting of zirconium oxide, single crystals growing stabilized zirconium oxide, melting of YBCO-based superconductor as well as a mix of zirconium and aluminium oxides have been carried out in the cold crucibles, while the inductor crucible was used for low temperature glass melting. Energy balance of melting process for different oxides and glasses is presented. Several ways how to start the melting process in cold crucible or inductor-crucible are described.
