red-brown corundum is made up of aluminium oxides and is distinguished by its ability to rapidly abrade any type of material.
corindonul roșu-brun este compus din oxid de aluminiu și se distinge prin capacitatea de a șlefui rapid orice tip de material.
the substrate preparation includes choosing an appropriate material and its crystallographic orientation; cleaning it, often with a diamond powder to abrade a non-diamond substrate; and optimizing the substrate temperature (about ) during the growth through a series of test runs.
