FIELD: chemistry.
SUBSTANCE: to obtain corundum microfilm layer of corundum is precipitated on film base or drum from material with reduced adhesion, as such applied is fluoroplast, after that, corundum film is removed from film base or drum. Layer of corundum can be precipitated on film base from sublimated material, as such applied is fluoroplast-4, with further sublimation of base. Also corundum layer is precipitated on film base from soluble material, as such applied is nitrocellulose, with further dissolution of base. In addition to this, to obtain corundum microfilm corundum layer is precipitated on film base or drum from melting material, as such applied is tin, after which film base or drum is melted and corundum layer is separated.
EFFECT: invention makes it possible to obtain corundum microfilm of higher strength and elasticity.
