Boron nitrideyumbu na roba ne na zamani wanda ke zuwa a cikin foda da siffa mai ƙarfi.Boron nitridewani abu ne na gaske na musamman saboda halayensa na musamman, waɗanda suka haɗa da ƙarfin zafi mai ƙarfi, ƙayyadaddun yanayin zafi na musamman, sauƙin machining, lubricity, ƙarancin dielectric akai-akai, da haɓaka ƙarfin dielectric.

Boron nitrideyawanci ana kiransa "fararen graphite" a cikin sigar sa mai ƙarfi saboda kwatankwacinsa na ƙaramin tsari zuwa graphite. Koyaya, ba kamar graphite ba, boron nitride shine mafi kyawun insulator na lantarki tare da mafi girman zafin jiki. Yana da ƙarfi mai ƙarfi na thermal conductivity da thermal shock juriya kuma ana iya sarrafa shi don kusanci haƙuri a kusan kowane nau'i. Yana shirye don amfani bayan machining kuma baya buƙatar ƙarin magani mai zafi ko hanyoyin wuta.

Amfani:

• Kyakkyawan machinability

• Ƙananan yawa

• High zafi watsin

• Babban tsayayyar wutar lantarki

• Kyakkyawan rashin kuzarin sinadarai

• Kyakkyawan juriya mai girgiza thermal

• Mai jure lalata

• Rashin zaman lafiya

• Low dielectric akai-akai (k=4)

• Anisotropic (ƙaddamarwar thermal ya bambanta tsakanin layi ɗaya da jirage masu tsayi zuwa hanyar dannawa).

• Kayan zafi mai zafi

• Ƙarfin rushewar dielectric> 40 KV/mm

40 KV/mm

Aikace-aikace:

• 1. Maɗaukakin Ƙarfe da Semiconductor:

• Kwale-kwalen Haɓaka: Ana amfani da shi don shigar da fim ɗin aluminium, muhimmin sashi a cikin kasuwancin marufi (misali, jakunkunan kayan abinci).

• Kayan aikin narkewar ƙarfe sun haɗa da crucibles, bututu, da nozzles don isar da narkakkar aluminum, da masu rarrabawa da abubuwan bawul don narkewar ƙarfe masu tsafta ko semiconductor.

Atsaye Ci gaba da Simintin Rabuwar Zobba: Tabbatar da rushewar sassauƙa da ƙarewar saman yayin ci gaba da simintin ƙarfe ko tagulla.

• 2. Electronics, Injiniyan Wutar Lantarki, Gudanar da Zazzabi:

• Abubuwan Rarraba Zafi: Ana amfani da su a cikin manyan LEDs, na'urorin mitar mitar rediyo, kayan aikin IGBT, da sauran aikace-aikace don cimma ma'auni mafi kyawu na rufin lantarki da ma'aunin zafi.

Abubuwan wutar lantarki masu ƙarfi sun haɗa da insulators masu zafi mai zafi, nozzles arc na plasma, da na'urorin canza ƙarfin wutar lantarki.

• 3. Aerospace da Tsaro:

• Radar Windows da Radomes: Nuna ingantattun kaddarorin bayyana raƙuman ruwa (masu gaskiya zuwa microwaves) kuma suna iya jure girgiza zafin iska, ana amfani da su a cikin makamai masu linzami, radar, da sauran kayan aiki.

Maɗaukakin Maɗaukakin Zazzabi: Ana amfani da shi a cikin bearings, titin jagora, da sauran yanayi masu tsauri.
