Proprietà termiche dei pezzi in ceramica di zirconio

---

Ceramica di zirconio, as an advanced engineering ceramic material, have been widely used in the global industrial field due to their unique thermal and physical properties.

Thermal performance characteristics of zirconia ceramics

1. Extremely high temperature resistance performance
   -Temperature range of use: Zirconia ceramics can maintain structural stability in environments up to 2400 ° C
   -Melting point: reaching 2715 ° C, much higher than most metals and alloys
   -Long term working temperature: can work stably for a long time within the range of 1100-1400 ° C
2. Excellent thermal insulation performance
   -Bassa conduttività termica: The thermal conductivity at room temperature is only 2-3 W/(m · K), which is about one-third of that of alumina ceramics
   -Low thermal diffusivity: effectively slowing down the heat transfer rate
   -High temperature insulation: can maintain excellent insulation characteristics even in high temperature environments
3. Excellent thermal shock stability
   -Basso coefficiente di espansione termica: about 10 × 10 ⁻⁶/K, close to metallic materials
   -High fracture toughness: significantly improved thermal shock resistance through phase transformation toughening mechanism
   -Resistenza agli shock termici: able to withstand rapid temperature changes without breaking
4. Phase transition characteristics and thermal stability
   -Phase transition temperature control: Control the phase transition temperature by adding stabilizers (such as yttrium oxide)
   -High temperature phase stability: ensuring structural integrity is maintained over a wide temperature range
   -Thermal cycle durability: minimal performance degradation after multiple thermal cycles
