ASTM F7 Aluminum Oxide Powder Specification Testing
ASTM F7 aims to cover specifications for aluminum oxide (alumina) powder in two classes of particle size, two chemical grades, and two levels of acidity. Which in turn is used as an insulating coating or as an ingredient of ceramic mixtures for components of electronic devices. The values stated in SI units are to be regarded as standard.
