Aluminum Oxide Crucible AL2O3 Crucible
gabatarwar samfur
Aluminum oxide crucible wanda aka fi sani da corundum crucible, mutane yawanci za su alumina abun ciki a cikin fiye da 95% crucible da ake kira corundum crucible.Corundum crucible yana da ƙarfin narkewa, juriya mai girma, juriya na acid da alkali, juriya na sanyi da zafi, juriya na lalata sinadarai.Ya dace da wasu abubuwa masu rauni na alkaline irin su Na2CO3 mai anhydrous a matsayin samfuran narkewa, amma ba don Na2O2, NaOH, da sauransu ba. rufi da inji ƙarfi a redox yanayi na 1650 ℃ -1700 ℃, tare da matsakaicin zafin jiki na 1800 ℃ a cikin gajeren lokaci.Dangane da yanayin aikace-aikacen, alumina crucibles suna samuwa a cikin girma da siffofi daban-daban.
Babban Siffofin
Babban fasali na alumina yumbu crucible: juriya mai zafi na kusan digiri 1200, dacewa da K2S207 da sauran samfuran narkewar kayan acid.Gabaɗaya, bai kamata a yi amfani da shi don narkar da Na0H, Na202 da Na2CO3 ba, don kar a lalata crucible na pocelain.Porcelain crucible ba zai iya hulɗa da hydrofluoric acid ba.
Alumina yumbu crucible za a iya tafasa HCl don tabbatar da tsarki na kayan da high zafin jiki juriya.Kayan yana da girma mai yawa, kyakkyawan juriya na iskar shaka, 400-500 digiri mafi girma fiye da kayan graphite, har zuwa digiri 900 mafi girma, tsawon rayuwar sabis.Tare da babban juriya na zafi, ƙarancin haɓaka haɓaka haɓakar thermal, zafi mai kyau da juriya mai ƙarfi da juriya mai kyau.Ayyukan sinadarai yana da karko kuma a zahiri baya amsawa tare da narkar da ƙarfe, inganta tsabtar gami.
(1) Saukin wankewa da tsafta.Gilashin yumbu mai laushi yana da haske kuma mai laushi, kuma yana da sauƙin wanke bayan amfani.
(2) Porcelain stoma kadan ne, kuma yawan sha ruwa yayi kadan.Ajiye bayani tare da yumbu crucible da tsattsauran hatimi na iya hana haɓakawa, kutsewa da mamaye ƙwayoyin cuta na waje.
(3) Natsuwar sinadarai da karko.Wannan batu ya fi na karfe irin su jan karfe, iron, aluminum, da dai sauransu, yumbu crucible yana da wani juriya ga acid, alkali, gishiri da yashwar iskar gas a cikin yanayi, ba sauki a sami sinadarai tare da waɗannan abubuwa ba, ba tsatsa ba. tsufa.
(4) Kyakkyawan kwanciyar hankali na thermal da jinkirin canja wurin zafi.Ceramic crucible yana da aikin zuwa wani bambancin zafin jiki, wanda ya fi kyau fiye da gilashin gilashi, yana da mummunan zafi na zafi, jinkirin canja wurin zafi, ana amfani da shi don riƙe ruwan zãfi ko bayani mai zafi, ƙarshen ba ya da zafi sosai.
Aikace-aikacen samfur
Alumina ne sosai yadu amfani, Electronics, man fetur, sunadarai, refractory, tukwane, robobi, yadi, takarda, da Pharmaceutical da yawa sauran filayen za a iya gani ta adadi, shi ne gaba ɗaya musamman Properties na alumina da aluminum hydroxide.Duk da haka, fiye da kashi 90 na alumina ana amfani dashi azaman albarkatun ƙasa don aluminium electrolytic.
A halin yanzu, akwai nau'ikan nau'ikan da ba alumina ba don magani, sama da nau'ikan 300, kowannensu yana da kyawawan halaye na zahiri da sinadarai, amma farashin ya fi alumina don magani.
A high tsarki ultrafine alumina, misali, saboda ta high narkewa batu, high taurin, high juriya, mai kyau inji Properties, sa juriya, lalata juriya, zafi juriya da sauran kyau kwarai 2.Main Featuress, don haka ne yadu amfani da guda crystal kayan. , ci-gaba ain, wucin gadi kashi, semiconductor, nika kayan, hadedde kewaye substrate, rikodi tef filler, kara kuzari da ta m, Laser kayan, yankan kayan aikin, da dai sauransu
