Application Summary AI generated
GB/T 32661-2016 specifies the classification, technical requirements, test methods, inspection rules, and packaging for spherical silica powder used as a filler material. It is primarily applied in the electronics industry for encapsulating integrated circuits and manufacturing high-frequency printed circuit boards, where the powder's spherical shape ensures uniform dispersion and low thermal expansion. The standard also applies to the production of advanced ceramics and coatings requiring high-purity, flowable silica particles.
