Submicron α-Al₂O₃ at 99.5% Al₂O₃. Formulated to your sintering route, not selected from a catalogue.
Mechanical values characterise specimens pressureless-sintered at 1550 °C, not the as-supplied powder. Data obtained on development batches; typical values, not a guaranteed specification.

Every product ships with its characterization report, referenced to the specification it was built against. Where a value is not measured, it is not published.
Where a published grade does not fit the requirement, a paid evaluation puts your specification through the same measurement stack.
