Izici ezinhlanu ze-high-purity alumina powder

1. Ukumelana namakhemikhali;
2. I-alumina ehlanzekile ephezulu, okuqukethwe kwe-alumina kukhulu kunama-99%;
3. Ukumelana nokushisa okuphezulu, ukusetshenziswa okuvamile ku-1600 ℃, isikhathi esifushane ngu-1800 ℃;
4. Ukumelana nokubanda okungazelelwe nokushisa, akulula ukuqhuma;
5. Ithatha i-grouting futhi inokuminyana okuphezulu.
1. Ukusetshenziswa kohlobo lwe-alumina powder

Ku-crystal lattice ye-α-type alumina powder, ama-ion komoyampilo agcwele eduze kuma-hexagon, futhi i-Al3+ isatshalaliswa ngokulinganayo kusikhungo sokuxhumanisa i-octahedral ezungezwe ama-ion komoyampilo.Amandla e-lattice makhulu kakhulu, ngakho-ke indawo yokuncibilika nendawo yokubilisa iphakeme kakhulu.I-α-type oxidation I-Aluminium ayincibiliki emanzini ne-asidi.Ibizwa nangokuthi i-aluminium oxide embonini.Yimpahla eyisisekelo esetshenziswayo yokwenza i-aluminium yensimbi;iphinde isetshenziselwe ukwenza izitini ezihlukahlukene eziphikisayo, izinsimbi eziphikisayo, amashubhu aphikisayo, nezinsimbi zokuhlola izinga lokushisa eliphezulu;ingasetshenziswa futhi njengama-abrasives nama-flame retardants.Ama-ejenti, izigcwalisi, njll.;high-purity α-type alumina iphinde ibe impahla eluhlaza ukukhiqizwa corundum yokwenziwa, irubi yokwenziwa kanye nesafire;iphinde isetshenziselwe ukukhiqizwa kwamasekethe ahlanganisiwe esimanje amakhulu.

I-alumina ecushiwe inomthamo okhethiwe we-adsorption wegesi, umhwamuko wamanzi kanye nomswakama othile owuketshezi.Ngemuva kokuthi i-adsorption isigcwele, ingavuselelwa ngokushisisa cishe ku-175-315°C ukuze kukhishwe amanzi.I-Adsorption nokuvuka kungenziwa izikhathi eziningi.Ngaphezu kokusetshenziswa njenge-desiccant, ingakwazi futhi ukukhangisa umhwamuko wamafutha okugcoba ovela ku-oxygen engcolile, i-hydrogen, i-carbon dioxide, igesi yemvelo, njll. Ingasetshenziswa futhi njenge-catalyst ne-catalyst carrier kanye ne-chromatography carrier.

I-Alumina powder iyisisetshenziswa esiyinhloko sokukhiqizwa kwezingothi ze-aluminium.Inezici zokundiza okukhanyayo, ukugeleza kwamanzi okuhle, ukuhlakazeka kalula nokumunca okuqinile kwe-fluorine.Ilungele ukukhiqizwa kwe-aluminium yensimbi nge-electrolysis kasawoti encibilikisiwe.Kubuye kube yinto ebalulekile yokukhiqiza i-corundum, i-ceramics kanye ne-refractories.
