Beryllium oxide ceramics yokhala ndi matenthedwe apamwamba komanso mawonekedwe otsika otayika
Zida za ceramic za BeO pakadali pano zimagwiritsidwa ntchito kwambiri, mapaketi a microwave amphamvu kwambiri, ma transistor amagetsi othamanga kwambiri, komanso zida zamitundu yambiri. Kugwiritsa ntchito zinthu za BeO kumatha kuwononga kutentha komwe kumapangidwa mudongosolo munthawi yake kuti zitsimikizire kukhazikika komanso kudalirika kwadongosolo.
BeO imagwiritsidwa ntchito pakuyika ma transistor amagetsi apamwamba kwambiri
Zindikirani: Transistor ndi chida cholimba cha semiconductor, chomwe chimazindikira, kukonza, kukulitsa, kusintha, kuwongolera ma voltage, kusinthasintha kwa siginecha ndi ntchito zina. Monga mtundu wa kusintha kosinthika kwapano, transistor imatha kuwongolera zomwe zimachokera kutengera mphamvu yamagetsi. Mosiyana ndi masiwichi amakina wamba, ma transistors amagwiritsa ntchito matelefoni kuti aziwongolera kutsegulira kwawo ndi kutseka kwawo, ndipo liwiro losinthira limatha kukhala lachangu kwambiri, ndipo kuthamanga kwa labotale kumatha kufika kupitilira 100GHz.
Kugwiritsa Ntchito Mu Nuclear Reactors
Nuclear riyakitala ceramic chuma ndi chimodzi mwa zinthu zofunika ntchito reactors, mu reactors ndi maphatikizidwe reactors, ceramic zipangizo kulandira mkulu-mphamvu particles ndi ma radiation a gamma, choncho, kuwonjezera kutentha kukana, dzimbiri kukana, ceramic zipangizo ayeneranso kukhala zabwino. kukhazikika kwamapangidwe. Manyutroni owunikira ndi oyang'anira (oyang'anira) amafuta a nyukiliya nthawi zambiri amakhala BeO, B4C kapena zida za graphite.
Beryllium oxide ceramics ali ndi kutentha kwapamwamba kwambiri kuposa chitsulo, kachulukidwe kakang'ono kuposa chitsulo cha beryllium, mphamvu yabwino pa kutentha kwakukulu, kutentha kwapamwamba, komanso kutsika mtengo kuposa zitsulo za beryllium. Ndi oyenera ntchito monga wonyezimira, woyang'anira ndi kubalalitsidwa gawo kuyaka pamodzi mu riyakitala. Beryllium oxide ikhoza kugwiritsidwa ntchito ngati ndodo yowongolera mu zida zanyukiliya, ndipo imatha kuphatikizidwa ndi zida za ceramic za U2O kukhala mafuta a nyukiliya.
High-Grade Refractory - Special Metallurgical Crucible
Chopangidwa ndi BeO ceramic ndi chinthu chotsutsa. Mitsuko ya BeO ceramic crucibles ingagwiritsidwe ntchito kusungunula zitsulo zosawerengeka komanso zamtengo wapatali, makamaka pamene zitsulo zoyera kwambiri kapena zosakaniza zimafunika. Kutentha kwa ntchito ya crucible kumatha kufika 2000 ℃.
Chifukwa cha kutentha kwake kosungunuka (pafupifupi 2550 ° C), kukhazikika kwamankhwala (kukana kwa alkali), kukhazikika kwamafuta ndi chiyero, zoumba za BeO zitha kugwiritsidwa ntchito kusungunula glaze ndi plutonium. Kuphatikiza apo, ma crucibles akhala akugwiritsidwa ntchito bwino popanga zitsanzo zasiliva, golide ndi platinamu. Kuchuluka kwa "transparency" ya BeO kupita ku radiation ya electromagnetic kumapangitsa kuti zitsanzo zachitsulo zisungunuke ndi kutentha kwa induction.
Ntchito Zina
a. Zoumba za Beryllium oxide zimakhala ndi matenthedwe abwino, omwe ndi maulalo awiri apamwamba kuposa quartz yomwe imagwiritsidwa ntchito nthawi zambiri, kotero laser imakhala ndi mphamvu zambiri komanso mphamvu yayikulu yotulutsa.
b. BeO ceramics akhoza kuwonjezeredwa ngati gawo la galasi la nyimbo zosiyanasiyana. Galasi yokhala ndi beryllium oxide yomwe imatumiza ma X-ray. Machubu a X-ray opangidwa ndi galasili amagwiritsidwa ntchito posanthula kapangidwe kake komanso zamankhwala pochiza matenda apakhungu.
Beryllium oxide ceramics ndi zida zina zamagetsi ndizosiyana, mpaka pano, matenthedwe ake apamwamba komanso mawonekedwe otsika otsika ndizovuta kusinthidwa ndi zida zina.
