Ukuqonda okuqhelekileyo kwezixhobo ze-magnesium alloy
(1) Amandla kunye nokuqina kwe-polycrystals ye-magnesium ecocekileyo ayiphezulu.Ke ngoko, i-magnesium ecocekileyo ayinakusetyenziswa ngokuthe ngqo njengesixhobo solwakhiwo.I-magnesium ecocekileyo idla ngokusetyenziselwa ukulungisa i-magnesium alloys kunye nezinye i-alloys.(2) I-Magnesium alloy yeyona nto iluhlaza yobunjineli eneyona d...Funda ngokugqithisileyo -
Malunga neSicelo saseThiourea kunye noHlalutyo loShishino lweMarike
I-Thiourea, kunye ne-molecular formula ye (NH2) 2CS, i-orthorhombic emhlophe okanye i-acicular bright crystal.Iindlela zamashishini zokulungiselela i-thiourea ziquka indlela ye-amine thiocyanate, indlela ye-lime nitrogen, indlela ye-urea, njl. Kwindlela ye-lime nitrogen, i-nitrogen yekalika, igesi ye-hydrogen sulfide kunye namanzi...Funda ngokugqithisileyo -
IGallium: Umgangatho wexabiso umiselwe ukunyuka ngo-2021
Amaxabiso e-Gallium anyuke ngasekupheleni kuka-2020, avala unyaka nge-US $ 264 / kg Ga (99.99%, imisebenzi yangaphambili), ngokwe-Asian Metal.Oko kuliphindaphinda ixabiso laphakathi enyakeni.Ukusukela nge-15 kaJanuwari 2021, ixabiso linyuke laya kutsho kwi-US$282/kg.Unikezelo lwexeshana / ukungalingani kwemfuno kubangele ukunyuka kunye novakalelo lwentengiso ...Funda ngokugqithisileyo -
Uphononongo lwentengiso yeveki enye yesilicon calcium yaseChina
Okwangoku, umgangatho wesizwe waseTshayina we-silicon calcium 3058 womgangatho wexabiso eliqhelekileyo lokuthumela ngaphandle kwi-FOB 1480-1530 yeedola zase-US / toni, ukuya kwi-30 yeedola zase-US / toni.NgoJulayi, i-8 / 11 i-arc furnaces kwimarike ukuvelisa i-silicon calcium, i-3 ibilungiswa.Unciphiso oluhambelanayo lwemveliso, ...Funda ngokugqithisileyo
