Alumina foda: foda sihiri don inganta aikin samfur
A cikin bitar masana'anta, Lao Li ya damu da tarin kayayyakin da ke gabansa: bayan ya harba wannan rukunin.yumbu substrates, ko da yaushe akwai ƙananan tsagewa a saman, kuma ko ta yaya aka daidaita zafin kiln, yana da ɗan tasiri. Lao Wang ya zo, ya dube shi na ɗan lokaci, ya ɗauki jakar farin foda a hannu: "Ka yi ƙoƙarin ƙara wasu daga cikin wannan, Lao Li, watakila zai yi aiki." Lao Wang ƙwararren masanin fasaha ne a masana'anta. Ba ya yawan magana, amma koyaushe yana son yin tunani game da sabbin kayayyaki iri-iri. Lao Li ya ɗauki jakar da rabi, kuma ya ga alamar ta ce "alumina foda".
Alumina foda? Wannan sunan yana kama da na yau da kullun, kamar dai foda na yau da kullun a cikin dakin gwaje-gwaje. Ta yaya zai zama "foda sihiri" wanda zai iya magance matsaloli masu wuyar gaske? Amma Lao Wang ya nuna shi da gaba gaɗi kuma ya ce: "Kada ku raina shi. Da ikonsa, zai iya magance yawancin ciwon kai."
Me yasa Lao Wang ke sha'awar wannan farin foda da ba a iya ganewa sosai? Dalilin shi ne ainihin mai sauƙi-lokacin da ba za mu iya canza duk duniya cikin sauƙi ba, za mu iya gwada ƙara wasu "sihiri foda" don canza aikin mahimmanci. Misali, lokacin da yumbu na gargajiya ba su da tauri kuma suna da saurin fashewa; karafa ba su da juriya ga yanayin zafi mai zafi; kuma robobi suna da ƙarancin ƙarancin thermal, foda alumina a hankali ya bayyana kuma ya zama "dutse mai taɓawa" don magance waɗannan mahimman matsalolin.
Lao Wang ya taɓa fuskantar irin wannan matsala. A wannan shekarar, yana da alhakin wani ɓangaren yumbu na musamman wanda ya buƙaci ya zama mai wuya, mai tsanani, da kuma tsayayya da yanayin zafi.Kayan yumbu na al'adaana harbawa, kuma ƙarfin ya isa, amma za su fashe a lokacin taɓawa, kamar guntun gilashin mara ƙarfi. Ya jagoranci tawagarsa sun jure dare da rana a cikin dakin gwaje-gwaje, akai-akai gyara dabarar da harbe-harbe bayan kunnuwa, amma sakamakon ya kasance cewa ƙarfin bai kai ga ma'auni ba ko kuma raguwa ya yi yawa, kullum yana fama da rashin ƙarfi.
"Wadannan kwanaki sun kasance masu kona kwakwalwa da gaske, kuma na yi asarar gashi da yawa." Daga baya Lao Wang ya tuna. A ƙarshe, sun yi ƙoƙarin ƙara ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun foda na alumina mai tsabta wanda aka sarrafa daidai a cikin albarkatun yumbura. Lokacin da aka sake buɗe murhu, wani abin al'ajabi ya faru: sabbin sassan yumbu da aka harba sun yi sauti mai zurfi da daɗi lokacin buga. Lokacin ƙoƙarin karya shi da ƙarfi, ya jure da ƙarfi da ƙarfi kuma ba ya karye cikin sauƙi - ƙwayoyin alumina sun tarwatse daidai gwargwado a cikin matrix, kamar dai an saƙa da ingantaccen hanyar sadarwa mara ganuwa a ciki, wanda ba wai kawai ya inganta taurin ba, amma kuma cikin nutsuwa ya mamaye tasirin tasirin, yana inganta haɓakar brittleness.

Lao Wang a hankali ya zana ƙaramin barbashi akan takarda: "Duba, wannan ƙaramin alumina yana da taurin gaske, kwatankwacin sapphire na halitta, da juriya na aji na farko." Ya dakata da cewa, “Mafi mahimmanci, yana da juriya ga yanayin zafi, kuma sinadaransa suna da tsayayye kamar Dutsen Tai, ba ya canja yanayinsa a cikin wuta mai zafi, kuma ba ya saurin sunkuyar da kansa cikin acid mai karfi da alkalis, haka nan kuma yana da kyaun zafi, kuma zafi yana tafiya da sauri a cikinsa.”
Da zarar an shigar da waɗannan halaye masu zaman kansu daidai cikin wasu kayan, kamar juya duwatsu zuwa zinariya. Alal misali, ƙara shi zuwa yumbu na iya inganta ƙarfi da taurin yumbu; gabatar da shi zuwa kayan haɗin ƙarfe na tushen ƙarfe na iya haɓaka juriya da ƙarfin jure yanayin zafi; har ma da ƙara shi zuwa duniyar filastik na iya ƙyale robobi suyi saurin tafiyar da zafi.
A cikin masana'antar lantarki,alumina fodakuma yana yin "sihiri". A zamanin yau, wace babbar wayar hannu ko kwamfutar tafi-da-gidanka ba ta damu da dumama ciki yayin aiki ba? Idan zafin da ke haifar da daidaitattun kayan lantarki ba za a iya bazuwa cikin sauri ba, aikin zai yi jinkiri a mafi kyau, kuma guntu zai lalace a mafi muni. Injiniyoyi da wayo suna cika babban zafin zafin jiki na alumina foda zuwa cikin siliki na musamman na zafin zafi ko robobin injiniya. Waɗannan kayan da ke ɗauke da foda alumina ana haɗe su a hankali zuwa ainihin abubuwan samar da zafi, kamar amintaccen “hanyar tafiyar da wutar lantarki”, wanda cikin sauri da inganci yana jagorantar zafi mai zafi akan guntu zuwa harsashi mai zafi.

Lao Wang sau da yawa yana cewa: "Ainihin 'sihiri' ba ya cikin foda kanta, amma ta yadda muka fahimci matsalar kuma mu nemo mahimmin batu da zai iya yin amfani da aikin." Ƙarfin alumina ba a halicce shi daga kome ba, amma ya fito ne daga abubuwan da ya fi dacewa da shi, kuma an haɗa shi da kyau a cikin wasu kayan, ta yadda zai iya yin amfani da karfi a lokacin mahimmanci kuma ya juya lalacewa zuwa sihiri.
