Analysis of Model and Key Indicators
Model classification and core differences
Key indicator description
ZrO ₂ (HfO ₂) content:
Yttrium stabilized powder ≥ 94.8%, high-purity powder ≥ 99.9%, determines the basic purity of the product.
Y ₂ O ∝ content:
5.2 ± 0.2%, used to stabilize zirconia crystal structure and improve ceramic toughness.
Impurity control:
The content of impurities such as Fe ₂ O3, Na ₂ O, SiO ₂ is extremely low to avoid affecting the sintering performance and color of ceramics.
Specific surface area (S2 BET): 6-25 m ²/g, which affects the activity of the powder and sintering temperature. The higher the value, the stronger the activity.
Median particle size (D ₅₀):
<0.5~<3.5 μ m, the finer the particle size, the higher the sintering density, suitable for fine ceramics.
Characteristics of granulation powder:
ZL series is a granulation material with good flowability, suitable for automated forming processes.
Usage and selection suggestions
General scenarios (such as ordinary structural ceramics and refractory materials):
YQ-3Y-QL series is preferred, with moderate cost and stable performance.
Molding process (such as dry pressing, injection molding): Choosing YQ-3Y-ZL granulation powder can greatly improve molding efficiency and billet uniformity.
High purity requirements (such as optical and semiconductor related devices):
Choose YQ-PZ series high-purity powder with extremely low impurity content to avoid defects during high-temperature sintering.
Particle size/specific surface area customization:
The powder particle size and specific surface area can be adjusted according to the customer's sintering process requirements to match different sintering curves.
