I-semiconductor esebenzisa ingalo yobumba ye-alumina emnyama

I-semiconductor esebenzisa isesekeli esimnyama se-alumina ceramic ingalo Isithombe esifakiwe

Incazelo emfushane:

Ukumelana nokugqokwa kwe-alumina ceramics kuyafana nalokho kwe-corundum, efinyelela izinga lobulukhuni be-Mohs 9, futhi ukumelana nokugqoka kuqhathaniswa nalokho kwama-alloys aqinile. Ukumelana nokushisa kwama-alumina ceramics kunezici ze-coefficient encane yokwandisa ukushisa, amandla aphezulu emishini kanye nokuhamba kahle kwe-thermal. Ngesikhathi esifanayo, i-alumina isetshenziswa kabanzi ezingxenyeni zemishini ezisetshenziswa ngaphansi kwezimo zokushisa eziphakeme ngenxa yokusebenza kwayo okuhle kakhulu kwezinga lokushisa (kufika ku-1700 ℃).

I-Alumina Ceramics

1. Ukuqina okuphezulu

Ukuqina kwe-Rockwell yi-HRA80-90, ubulukhuni buphansi kunedayimane, bungaphezulu kakhulu kokumelana nokugqokwa kwensimbi engagqoki nensimbi engagqwali.

2. Ukumelana nokugqoka okuhle kakhulu

Ikalwa izikhungo zocwaningo ezingochwepheshe, ukumelana kwayo nokugqokwa kulingana nezikhathi ezingama-266 zensimbi ye-manganese. I-Gaoming cast iron izikhathi ezingu-171.5, ngokweminyaka yethu engaphezu kweshumi yocwaningo lokulandela umkhondo wamakhasimende, ngaphansi kwezimo ezifanayo zokusebenza, inganweba impilo yesevisi yemishini okungenani izikhathi eziyishumi ngaphezulu.

3. Isisindo esincane

Ukuminyana kwayo kwe-3.5g/cm3 kuyingxenye kuphela yensimbi, enganciphisa kakhulu umthwalo wemishini.
