Barium yombala oxide

Ukusetshenziswa ezivame kakhulu into "barium yombala oxide" kusekelwe impahla yayo hygroscopic - ikhono zimunce amanzi. Ngakho-ke akuyona ngokuqondile umkhakha zamakhemikhali, isetshenziswa njengendlela wengxenye ngokukhiqiza barium yombala peroxide. Ngo umkhakha oxide lubaluleke ekukhiqizeni odonsa sobumba. Ngaphezu kwalokho, ngo izimo samanje barium yombala oxide kabani ifomula Bao, ngathola isicelo okukhulu Microelectronics nangezinto zobuchwepheshe. Ukuze kukhiqizwe ferrate usebenzisa barium yombala magnitokeramiki, okuyinto etholakala ngokuhlanganisa e namandla amakhulu kazibuthe kwengcindezi ingxube ka-barium yombala nensimbi oxide izimpushana.

Nokho, yagxila isicelo womshini cathodes amakheli ndawonye. Ekuqaleni kwekhulu elidlule, ososayensi evela eJalimane Venelt wafunda electron ekushayweni umthetho, okuyinto isanda wavula IsiZulu wamazwe Richardson. Ukuze ucwaningo Venelt esetshenziswa izingcezu platinum wire. Imiphumela yokuqala zokuhlola waqinisekisa ngokugcwele iziphetho ungenisa kamuva physics ngesiNgisi. Kodwa ke isipiliyoni kuhlulekile futhi Venelt wasikisela ukuba ukugeleza electron iphakeme kakhulu kunokujwayelekile, ngoba phezu kobuso ukusebenza impahla --platinum - babekwazi avele engahluziwe. Ngemva kokuhlola nokucabanga yayo Venelt wathola ukuthi ubukhulu umthombo electron ukugeleza kuka kuyinto barium yombala oxide, isehlakalo-platinum phezu njengengxenye amadivayisi igrisi lobuchwepheshe esetshenziswa ukuhlola. Iziphetho Venelta ngempela kwahlala isikhathi eside engaziwa ngoba ngempela abantu abasemkhakheni wezesayensi ayikwazanga Ucwaningo nokuzala okuhlangenwe nakho kwakhe. Kwathatha Kwacishe kwaphela ikhulu leminyaka le-physics IsiZulu Kohler kwafakazela ngokunemba Venelta. Kohler ngesisekelo ucwaningo okuphindaphindiwe yabonisa ukuthi uma barium yombala oxide is phansi Ukushisa at ingcindezi ngokuqhubekayo engezansi, amakheli ndawonye ekushayweni umfutho kwandisa ngokushesha.

Kuphela namathathu banesifo esibi sokukhohlwa leminyaka elidlule, usokhemisi German UPawulu wasikisela, liqukethe yokuthi ama-electron ocushiwe ngenxa khona ukungcola oxide ne-barium yombala. Phakathi ukuphendula, esiqhutshwa ngomfutho ongaphakeme, ingxenye oxygen ephunyuka oxide. Ukuhlala lapho barium yombala is ionized futhi ngaleyo ndlela ikhuthaza ukubukeka electron khulula. Lezi ama-electron kanye ababeletha kokushiya isakhiwo crystalline lapho evuthayo futhi ayeke wabukela Venelt.

Kwakungenxa nje ekuqaleni Engxenyeni leminyaka elidlule yesibili wagcina kwafakazela ubuqiniso lo mbono. Osokhemisi P. A. Bundeli Ulimi Kovtun (USSR) ayikwazanga kuphela ngamanani setha ukubaluleka lokuhlushwa amanyela emkhandweni oxide ne-barium yombala, kodwa nangenduduzo experiment ukuqhathanisa ukubaluleka kwayo nge amakheli ndawonye ukugeleza ubuningi. Yingakho oxide ne-barium yombala isetshenziswa isithako esebenzayo enkulu ekwakhekeni cathodes amakheli ndawonye. Njengoba isibonelo,-ugongolo-electron, lapho isithombe elakhiwe esikrinini elula ithelevishini noma i-computer ukuqapha. Ikhwalithi ekusakazeni umthombo lapha izenzo barium yombala oxide.

Uma ketshezi kuyinto ukuzama ukuncibilikisa emanzini, kutholakala ukuthi barium yombala oxide ihlangana emanzini ngokubeka amalahle ikhambi. etholwe Ngakho izidakamizwa barium yombala hydroxide - powder emhlophe nge iphuzu ukuncibilika 78 ° C. Le ngxube is wasithukuthelela enhle kakhulu carbon dioxide igesi, futhi ngenxa yalokho isixazululo aqueous, ngokuvamile ebizwa ngokuthi "amanzi barite", sisetshenziswa kabanzi njengendlela reagent ukuze carbon dioxide.

Egcekeni ukuqala futhi ingxenye oyifunayo ifakiwe Umbala izinto ezihlukahlukene, uthambise kanye amafutha. Ukusetshenziswa okunjalo barium yombala oxide wabikezela ngisho DI Mendeleev.
