High-purity alumina(Al2O3) evaporation material.

Sintered alumina evaporation materials contain a small amount of impurities as a binder.
These impurities can occasionally cause outgassing and splashing.
SHINKOSHA’s single crystal evaporation materials are binder-free, reducing such risks significantly.

For anti-reflection coatings, hard coatings, and chemical-resistant coatings, please use our alumina evaporation materials, which are manufactured in an integrated production system from crystallization to cleaning.
