Vanadium pentoxide (V₂O₅) ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale, makamaka popanga sulfuric acid komanso machitidwe osiyanasiyana a okosijeni. Mapangidwe ake apadera amankhwala, kukhazikika, komanso kuthekera kothandizira machitidwe a redox kumapangitsa kuti ikhale chisankho chabwino kwambiri chothandizira. Nkhaniyi ikufotokoza zifukwa zogwiritsira ntchito V₂O₅ monga chothandizira, njira zake zogwirira ntchito, ntchito zake m'mafakitale osiyanasiyana, komanso tsogolo la vanadium-based catalysis.

Silicon metal 553 ndi alloy yoyera kwambiri ya silicon yomwe imagwiritsidwa ntchito kwambiri m'mafakitale ambiri chifukwa cha mawonekedwe ake apadera akuthupi ndi mankhwala. Chigawo chake chachikulu ndi 98.5% silicon, yokhala ndi chitsulo chochepa ndi aluminium, chomwe chimalola chitsulo cha silicon 553 kukhalabe ndi mphamvu zabwino komanso kukana dzimbiri m'malo otentha kwambiri. Nkhaniyi ifotokoza mwatsatanetsatane ntchito zazikulu za silicon zitsulo 553, kuphatikiza ma aloyi a aluminiyamu, ma semiconductors, mafakitale a photovoltaic, ndi mafakitale amankhwala.

Silicon metal powder ndi mtundu wabwino, woyeretsedwa kwambiri wa silicon womwe umapangidwa pochepetsa silika mu ng'anjo zamagetsi zamagetsi. Ili ndi zitsulo zonyezimira ndipo imapezeka mumitundu yosiyanasiyana ya tinthu, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zosiyanasiyana. Silicon ndi chinthu chachiwiri chochuluka kwambiri padziko lapansi ndipo chimagwira ntchito ngati chinthu chofunikira kwambiri m'magawo ambiri, makamaka muukadaulo wa semiconductor, mphamvu ya dzuwa, ndi zitsulo.

Silicon metal powder ndi chinthu chosunthika chomwe chimagwiritsidwa ntchito mosiyanasiyana m'mafakitale osiyanasiyana. Makhalidwe apadera a silicon chitsulo ufa amapangitsa kuti ikhale yamtengo wapatali pazogulitsa ndi njira zambiri. M'nkhaniyi, tiwona zofunikira za silicon metal ufa ndikuwunika momwe zimagwiritsidwira ntchito mosiyanasiyana.

Ferrosilicon ndi alloy yofunika kwambiri yomwe imagwiritsidwa ntchito popanga zitsulo ndi zitsulo zina. Amapangidwa ndi chitsulo ndi silicon, ndi zinthu zina zosiyanasiyana monga manganese ndi carbon. Kupanga kwa ferrosilicon kumaphatikizapo kuchepetsa quartz (silicon dioxide) ndi coke (carbon) pamaso pa chitsulo. Izi zimafuna kutentha kwambiri ndipo zimakhala ndi mphamvu zambiri, zomwe zimapangitsa kuti mitengo yamtengo wapatali ikhale yofunika kwambiri pozindikira mtengo wonse wopanga ferrosilicon.

Ferrosilicon chimagwiritsidwa ntchito mu makampani zitsulo, mafakitale foundry ndi kupanga mafakitale ena. Amadya 90% ya ferrosilicon. Pakati pa magulu osiyanasiyana a ferrosilicon, 75% ferrosilicon ndi yomwe imagwiritsidwa ntchito kwambiri. M'makampani azitsulo, pafupifupi 3-5kg 75% ferrosilicon amadyedwa pa tani iliyonse yachitsulo yopangidwa.

Ferrosilicon nitride ndi silicon nitride zimamveka ngati zinthu ziwiri zofanana, koma kwenikweni, ndizosiyana kwambiri. Nkhaniyi ifotokoza kusiyana pakati pa ziwirizi mosiyanasiyana.

Ferromolybdenum ndi ferroalloy wopangidwa ndi chitsulo ndi molybdenum. Amapangidwa posungunula chisakanizo cha molybdenum concentrate ndi iron concentrate mu ng'anjo. Ferromolybdenum ndi aloyi yosunthika yomwe imatha kugwiritsidwa ntchito m'mafakitale osiyanasiyana.

Tungsten-iron alloys nthawi zambiri amatanthawuza ma alloys opangidwa ndi tungsten (W) ndi chitsulo (Fe). Nthawi zambiri, ma aloyi achitsulo a tungsten sakhala ndi maginito. Izi ndichifukwa choti tungsten yokha ndi chitsulo chosagwiritsa ntchito maginito, ndipo chitsulo chomwe chili mu aloyi achitsulo cha tungsten nthawi zambiri chimakhala chochepa, chomwe sichingapatse aloyiyo mphamvu yamaginito.

Titaniyamu si maginito.Izi ndichifukwa chakuti titaniyamu ili ndi mawonekedwe a kristalo opanda ma elekitironi osaphatikizidwa, omwe ndi ofunikira kuti chinthu chiwonetsere maginito. Izi zikutanthauza kuti titaniyamu sagwirizana ndi maginito ndipo imatengedwa ngati diamagnetic material.
