Maskaxda weyn ee Dunduh ee Dhulka: Lanthanum Ogide

Lanthanum Oxide,Qaaciddada molikaLa2o3, Miisaanka Molecular 325.8091. Badanaa loo isticmaalay soo saarida muraayadaha indhaha ee muraayadaha indhaha iyo fiilooyinka indhaha.

Hantida kiimikada

Waxoogaa yar ku milma biyaha oo si fudud u milmaa aashito aashitada si ay u sameeyaan cusbada u dhigma.

Hawada u soo gaadhay, way fududahay in la nuugo kaarboon-dioxide iyo biyo, si tartiib tartiib ah loo shido kaarboon-ka Lanthanum.

GubashadaLanthanum OgideWaxay isku daraan biyo si loo sii daayo kuleyl aad u badan.

hanti jireed

Muuqaalka iyo guryaha: budada adag ee adag.

Cufnaanta: 6.51 g / ml oo ah 25 ° C

Barta dhalaalaya: 2315 ° C, dhibic karkaraya: 4200 ° C

Xoolaha: Ku milatari aashitada iyo chloride chloride, oo ku dhex jira biyaha iyo ketones.

Habka wax soo saarka

1. Waxyaabaha ceyriinka ah ee habka soosaarka ayaa ah xalka dhaqaallada dhulka ee dhulka ka dib, kaas oo ka kooban qiyaastii 50% LA2O3, 116-7% PR6O5, iyo 30% ND2O3. Isku-darka σ XAALADAHA DHAQANKA Dhulka ee Dhulka oo leh Qiyaasta 320-330g / L of verkyl-ka iyadoo la adeegsanayo zosphylfyphonesosphonate (P350), ee P350), 35-38 marxaladaha soosaarka. Xalka haraaga ah ee ay kujirto Lanthanum ayaa laga takhalusay ammonia, oo ay ku dhejisay oxalic acid, ka dibna sifeeyo oo gubiso si loo helo wax soo saarka dhamaaday ee Lanthanum oxide. Waxaa laga soo saaray Cunthate-ka Lanthanum Phosphate ama diyaarinta adoo gubanaya kaarboon-ka Lanthanum ama amooniyam. Waxaa sidoo kale laga heli karaa kuleylka oo ay ka go'do oxanka oxaalka ee Lanthanum.

2. Dhig la (oh) 3-aad ee ku jirta salafka platinum, oo qalalan 200 ℃, gub 500 ℃, oo burburi in ka badan 840 ℃ si loo helo Lanthanum oxide.

Isticmaal

Badanaa loo isticmaalay soo saarida muraayadaha indhaha ee muraayadaha indhaha iyo fiilooyinka indhaha. Waxaa sidoo kale loo adeegsaday warshadaha elektiroonigga ah inay yihiin dafooyinka dhoobada ah iyo waxyaabaha lagu daro piezoelectic. Waxaa sidoo kale loo istcimaalaa sida shey ceyriin ah oo loogu talagalay soosaarka Lanthanum ee caajiska iyo sidii wax u dhinta batroolka.

Goobta Codsiga: Badanaa loo isticmaalo soo saarista muraayadda actor ee saxda ah, Golaha Fibcalical ee Sare, ee ku habboon samaynta kamaradaha, kamaradaha, iyo muraayadaha microscope, iyo xamuulka qalabka indhaha ee indhaha. Waxaa sidoo kale loo isticmaalaa soo saarista xasaasiyadaha dhoobada, xarkaha 'piezoelectric chopamic-ka', iyo alaabada raajada raajada sidaLanthanum bromidebudo. Waxaa laga soo saaray Cunthate-ka Lanthanum Plosphate ama ka helay gubashada kaarboon-ka lethanum ama amooniyam. Waxaa sidoo kale laga heli karaa kuleylka oo ay ka go'do oxanka oxaalka ee Lanthanum. Waxaa loo istcimaalay sidii falcelinno kala duwan oo loogu talagalay falcelinta kala duwan, sida cadeynta caleenta ee kaarboon monoksaydh markii lagu dhejiyay cadidhide-ka kaarboon men-ka kaarboon medeyne marka ay ku jiraan palfium mopane. Lanthanum ogide wuxuu ku dhexjiray lithium oxide ama zirconia (1%) waxaa loo isticmaali karaa soo saarida magnes-ka Ferrite. Waa uur-ku-dhafan xulasho si aad ah u ah xusullada oxidatikada ee metheane si loo soo saaro Ether iyo Ethylene. Waxaa loo isticmaalaa in lagu wanaajiyo ku tiirsanaanta heerkulka iyo astaamaha dilium titanate (batio3) iyo tittium titanate (SRtio3) Ferroelects, iyo sidoo kale waxsoosaarka aaladda optic oppic iyo muraayadaha indhaha.
