Yttria-stabilized Zirconia Round Bottomed Boat Crucible

Available Configurations

Properties common to all products in this list

Composition: ZrO₂/Y₂O₃ Form: Crucible Material: Zirconium Oxide CAS Number: 114168-16-0 Commodity: Ceramics
Yttria-Stabilized Zirconia (YSZ) Round-Bottomed Boat Crucible combines excellent thermal stability, corrosion resistance, and structural integrity in a geometry designed for optimal molten material handling. The round-bottom design promotes uniform heat distribution and minimizes localized thermal stress, while yttria stabilization ensures phase stability through repeated high-temperature cycles. Industries use these crucibles in vacuum evaporation, metal and glass melting, and advanced ceramic processing. Specific applications include producing high-purity optical coatings, alloying reactive metals, and calcining specialty ceramic powders. In research, they support studies on high-temperature material interactions, thermal barrier coating behavior, and controlled atmosphere processing. The combination of durable ceramic composition and shape-specific heating advantages makes them indispensable for both industrial and laboratory high-performance thermal applications.
