3mol%/5mol%/8mol%/13mol% Yttria Stabilized Zirconia Powder (abbreviated as 3Y/5Y/8Y/13Y YSZ powder)
Yttria = Yttria (Y₂O₃, stabilizer)
Stabilized Zirconia = Stabilized Zirconia (ZrO₂)
Powder = Powder
Yttria molar doping: 3Y = 3mol% Y₂O₃, 5Y = 5mol%, 8Y = 8mol%, 13Y = 13mol%

1. 3Y (3mol%) Y2O3 (3Y-TZP, tetragonal partially stabilized zirconia)
Crystal phase: Predominantly tetragonal, with the strongest phase transformation toughening effect.
Core advantages: Ultra-high fracture toughness, bending strength, wear resistance, and resistance to low-temperature aging.
Typical applications: Dental zirconia blocks/crowns and bridges, orthopedic implants, wear-resistant cutting tools, bearings, nozzles, electronic structural ceramics, and raw materials for cold isostatic pressing.

2. 5Y (5mol% Y2O3, high-transmittance tetragonal zirconia)
Crystal phase: Tetragonal, with a yttrium content higher than 3Y.
Core advantages: Significantly improved translucency, slightly lower strength than 3Y, and moderate toughness.
Typical applications: Anterior aesthetic all-ceramic restorations, high-transmittance dentures, optical ceramics, plasma-sprayed coatings, and oxygen sensor substrates.

3. 8Y (8mol% Y2O3) Y₂O₃ (8YSZ, Fully Cubic Stabilized Zirconia)
Crystal Phase: Pure cubic phase, no phase transformation toughening, decreased mechanical strength, but optimal oxygen ion conductivity.
Core Advantages: Strong high-temperature ionic conductivity, good thermal stability, no phase transformation cracking at high temperatures.
Typical Applications: Solid oxide fuel cell (SOFC) electrolyte, high-temperature oxygen sensor, thermal barrier coating, high-temperature refractory ceramics, high-temperature sealing components.

4. 13Y (13mol% Y₂O₃, High-Yttrium Fully Stabilized Cubic Zirconia)
Crystal Phase: High-Yttrium cubic phase, higher ionic conductivity than 8Y, weakest mechanical properties.
Core Advantages: Extremely low electronic conductivity, ultra-wide temperature range oxygen ion conduction, high-temperature corrosion resistance.
Typical Applications: High-precision high-temperature oxygen probe, special high-temperature electrolyte, laboratory electrochemical components, coatings for extreme high-temperature conditions.

1. Higher yttrium oxide doping content → higher light transmittance and ionic conductivity; lower toughness and flexural strength.
2. 3Y: The mechanical ceiling, mainly used in biomedicine and wear-resistant structural components.
3. 5Y: Aesthetically translucent, primarily for anterior tooth restorations
4. 8Y/13Y: Ion-conductive, primarily for energy and high-temperature sensing applications
