Sintering results describe the brochure’s test specimen and processing route. They are not the mechanical properties of loose powder.
| Additional sintering result | Brochure value |
|---|---|
| Cross-section grain size after the reported 1350°C route | 0.5 µm |
The brochure also describes a density of approximately 3.96 g/cm³ at 1500°C. These are sintered specimen results, distinct from the loose powder bulk density and secondary particle size.
CUSTOMIZATION
Specify particle-size requirements, impurity limits, packing and the intended dispersion or sintering route.
APPLICATION
