Umhlinzeki we-Antimony Sulfide (i-Antimony Trisulfide) eNingizimu Afrika

Kuyini i-Antimony Sulfide?

I-Antimony trisulfide (Sb₂S₃), eyaziwa nangokuthi i-antimony sulfide noma i-stibnite ngesimo sayo samaminerali, iyimpuphu enombala obomvu ophuzi kuya komnyama kuye ngobukhulu bezinhlayiya kanye nesimo sekristalu. Isimo se-orange esingenasimo (esinqunyiwe) kanye nesimo esimnyama esikristalu (stibnite) zinezakhiwo nezinhlelo zokusebenza ezahlukene. Ihlanganisa ukusabela kwe-sulfide nezakhiwo ezihlukile ze-antimony, okwenza ibe yigugu ku-pyrotechnics, izinto zokungqubuzana, kanye nocwaningo lwe-semiconductor.

Izinto Zokungqubuzana Nama-Brake Pads

I-Antimony sulfide iyisici esibalulekile ezintweni zokungqubuzana kwezimoto, okuhlanganisa ama-brake pad, ama-brake linings, kanye nama-clutch facings. Isebenza njenge-lubricant kanye ne-anti-squeal agent eqinisa ukuziphatha kokungqubuzana ebangeni elibanzi lokushisa. Uma ihlanganiswe nezinye iziguquli zokungqubuzana kanye nama-binder ekwakhiweni okungena-asbestos, isiza ekufezeni ukusebenza kokubhuleka okuhambisanayo, okulawulwayo ezisetshenzisweni zezimoto ezisindayo kanye nezabagibeli.

Ama-pyrotechnics kanye nokufana kokuphepha

Ku-pyrotechnics, i-antimony sulfide isetshenziswa njengengxenye kaphethiloli ezinhlanganisweni ze-flash, ikhiqiza ukukhanya okumhlophe okukhanyayo uma kuhlanganiswa nama-oxidiser afana ne-potassium perchlorate noma i-potassium chlorate. Ama-Safety matches asebenzisa i-antimony sulfide ekwakhiweni kwekhanda, lapho ivutha khona ngokwethembeka uma ishaywa ku-striker strip ebomvu equkethe i-phosphorus. Imikhiqizo ye-pyrotechnic yezempi neyezentengiselwano isebenzisa ne-antimony sulfide ezinhlanganisweni zokulibaziseka kanye nama-primer.

Ama-semiconductor kanye ne-Specialty Coatings

I-Antimony sulfide iyinto ye-semiconductor (i-bandgap ~1.7 eV) edonsele ukunaka njenge-photovoltaic absorber kumaseli elanga amancane. Amaqembu ocwaningo ahlole i-Sb₂S₃ njengento yokumunca engeyona enobuthi, eningi emhlabeni. Iphinde isetshenziswe njenge-pigment kwezinye izinhlobo zeglasi ukukhiqiza imibala ephuzi e-orange, kanye nasezimbozweni ezikhethekile ezidinga ukuvikelwa kokugqwala okusekelwe ku-sulfide noma izakhiwo ezimunca i-infrared.
