Tšebeliso ea phofo ea α-aluminium ka thepa ea ho tlatsa
Ka thepa ea ho tlatsa, e le ho etsa bonnete ba hore e kopana hantle le lintho tse phelang le ho fokotsa tšusumetso ho viscosity ea tsamaiso, tlhokahalo ea motheo ka ho fetisisa bakeng sa α-Al2O3 ke hore metsi a lekaneng a lekaneng, haholo-holo a spherical, hobane e phahameng sphericity, bokaholimo.Ha matla a le manyenyane, a ntlafatsa metsi a holim'a bolo;ea bobeli, phofo ea α-Al2O3 e nang le nts'etsopele ea kristale e feletseng, bohloeki bo phahameng ba lik'hemik'hale le matla a phahameng a 'nete a matla a khoheli a na le conductivity e ntle ea mocheso le phello e molemo ha e sebelisoa bakeng sa thepa ea ho itšireletsa le ea thermally conductive.
Tšebeliso ea phofo ea α-alumina ka thepa ea capacitor corundum
Ka indasteri, phofo e hloekileng ea α-alumina e atisa ho silafatsoa ka sebōping sa mocheso o phahameng oa mocheso ho etsa corundum ea maiketsetso, e tsejoang hape e le fused corundum.Boitsebiso bona bo na le litšoaneleho tsa boima bo phahameng, lithōle tse hlakileng le likhutlo, 'me microstructure ka ho khetheha e haufi le spherical.Ts'ebetsong ea ho sila ka lebelo le phahameng, lithollo tsa abrasive li na le matla a matla a ho itšeha, 'me lithollo tse senyang ha li bonolo ho senya.ka tsela eo li eketsa bophelo ba eona ba tšebeletso.
