Alumina foda da α-type alumina powaer

1. Chemical juriya;
2. High-tsarki alumina, abun ciki na alumina ya fi 99%;
3. High zafin jiki juriya, al'ada amfani a 1600 ℃, gajeren lokaci 1800 ℃;
4. Juriya ga sanyi kwatsam da zafi, ba sauƙin fashe ba;
5. Yana rungumi grouting kuma yana da babban yawa.
1. Amfani da α-type alumina foda

A cikin lattice crystal na α-nau'in alumina foda, oxygen ions suna kusa da cushe a cikin hexagons, kuma Al3 + an rarraba shi cikin daidaituwa a cikin cibiyar daidaitawa ta octahedral kewaye da ions oxygen.Ƙarfin lattice yana da girma sosai, don haka wurin narkewa da wurin tafasa suna da girma sosai.α-type oxidation Aluminum ba shi da narkewa a cikin ruwa da acid.Ana kuma kiransa aluminum oxide a masana'antu.Yana da asali albarkatun kasa don yin karfe aluminum;Hakanan ana amfani da shi don yin bulo-bulo daban-daban, ƙwanƙwasa ƙwanƙwasa, bututun ƙarfe, da kayan gwajin zafin jiki;Hakanan za'a iya amfani dashi azaman abrasives da masu kare wuta.Ma'aikata, masu cikawa, da dai sauransu;high-tsarki α-type alumina kuma shine albarkatun kasa don samar da corundum na wucin gadi, rubi na wucin gadi da sapphire;Hakanan ana amfani da shi don samar da manyan hanyoyin haɗin gwiwar zamani.

Alumina da aka kunna yana da zaɓin adsorption damar iskar gas, tururin ruwa da wasu danshi na ruwa.Bayan adsorption ya cika, ana iya farfado da shi ta hanyar dumama a kimanin 175-315 ° C don cire ruwa.Adsorption da tashin matattu za a iya yi sau da yawa.Bugu da ƙari, ana amfani da shi azaman desiccant, yana kuma iya ɗaukar tururin mai daga gurɓataccen iskar oxygen, hydrogen, carbon dioxide, iskar gas, da dai sauransu. Hakanan ana iya amfani dashi azaman mai haɓakawa da mai ɗaukar hoto da chromatography.
