<p>The ceramic member consists substantially exclusively of pure BaZrO3 and/or SrZrO3. The ceramic member may constitute for instance a receptacle (1) for melting a material (15) and/or for processing a molten material (15) such as a superalloy or another metallic material or a material for forming an oxide superconductor. The ceramic member may also be adapted for shaping a molten or at least softened metallic material. The ceramic member may moreover constitute a part of an electric heating resistor or at least a part of a thermal insulation. The ceramic member may further constitute a substrate for supporting a thin epitaxial layer of an oxide superconductor. The ceramic member has a high melting temperature, is not submitted to crystallographic phase transitions between room temperature and the melting temperature, is mechanically and chemically stable up to high temperatures and is able to resist strong thermal shocks.</p> |
