FIELD: ceramics; computer engineering.
SUBSTANCE: disclosed are parts from transparent corundum ceramic materials which can be used in laminar materials for displays of underwater computers, mobile phones, tablets, protective hour glass and other scratch-resistant articles. Corundum parts are doped with magnesium oxide, yttrium oxide or lanthanum oxide with alloying additive content less than or equal to 2,000 parts per million, wherein average size of ceramics grains is less than 750 nm. Part has thickness of less than 800 mcm and porosity of less than 0.01 %.
EFFECT: technical result of the invention is production of ceramic parts with high transmission coefficient and low decay.
