High Purity Alumina Baikowski® alumina powder (corundum structure)

4 November 2015

Certificate of Analysis Standard Reference Material® 676a

National Institute of Standards & Technology

Gaithersburg
Baikowski® alumina powder is the source reference that NIST uses to define aluminum oxide and generate standard samples. The alumina powder was produced via the alum [NH4Al(SO4)2 • 12H2O] precursor route, calcined to 1400 °C, and jet milled to a fully disaggregated state. The alumina grains are sub-micrometer in size and equi-axial in shape. The high calcination temperature ensures high phase purity while the isometric form of the grains effectively eliminates preferred orientation effects in this powder. The disaggregated state of this material ensures the homogeneity of mixtures prepared by conventional methods.

High Purity Alumina BMA15

September 2020

Improved alumina transparency achieved by high-pressure spark plasma sintering of commercial powder

B. Ratzker, A. Wagner, S. Kalabukhov, N. Frage

Department of Materials Engineering, Ben-Gurion University of the Negev, Israel

Ceramics International 46 (2020) 21794–21799

With BMA15, a very fine and pure alpha alumina, and using a modified SPS sintering technique allowing to reach pressure as high as 600MPa, it is possible to produce very fine grain ceramic parts (170nm grain size), showing exceptional optical transparency (72.6% in-line transmittance at 640nm wavelength, very close to the theoretical limit) at rather low temperature (1100°C).
