silica and iron oxide containing alpha alumina particles is mechanism research

摘要

theoretical oxide. the prime minister, Al2O Fe2O 3, 3 and SiO 2 containing alpha alumina ceramic grinding mechanism, is greater than about 200 nanometer surface roughness height and the 3.50 g / u33a4 greater density. the ideal, alpha alumina ceramic grinding mechanism, the average particles size of about 0.5 micrometer pending u.s. (welcomed to take the 0.3 micrometer) of alpha alumina with a pending. with the SiO Fe2O 3. 2 the existence of abrasive particles of a grain to increase the quantity of crushing, grinding, sintering is one of, alpha alumina pending growth to reduce the abrasive particles, at least one or more of the grid size to expand. in general, to improve the performance of abrasive particles can be broken.from the perspective of the theory of oxide to the prime minister, Al2O 2, 3 and SiO containing alpha alumina ceramic grinding particle is the market mechanism.
