Is that Al2O3 correct? I didn't know that sapphire whiskers and
Aluminum oxide was the same material. Cool.
Al2O3 is the material that is released from the solid rocket motor
firings when pushing a satellite into higher orbits. This material
is among the most common debris material in orbit around the earth.
Here is a picture of an aluminum oxide sphere attached to a
micrometeroid (cosmic dust) particle:
