Popis:	Corrosion resistance of a sapphire surface has been studied as a function of various technological factors (growth method, presence of impurities, growth medium), the density of structural defects (pores, vacancies, dislocations), and the crystallographic characteristics. It is shown that the main contribution to the corrosion resistance depends on the type of the mechanical treatment and the crystallographic characteristics of the surfaces and that the resistance of different crystallographic planes to aggressive media can differ up to seven times.
