Barium oxide

Kushandisa vakawanda imwe pfuma "barium oxide" hunobva ayo hygroscopic pfuma - kwaniso yekubata mvura. Saka zvakananga makemikari indasitiri, rinoshandiswa sechiratidzo chinoumba hwokubereka barium peroxide. In indasitiri oxide hunokosha kweShanduro zvedongo magnets a. Uyezve, mune chipo mamiriro ezvinhu barium oxide ane yemaitiro Báo, ndakawana kushanda zvikuru microelectronics uye Electronics. Nokuti kugadzirwa ferrate kushandisa magnitokeramiki barium, izvo yaunganidzwa tichibatanidza zvakasimba remagineti pasi kwokudzvinyirira musanganiswa barium nesimbi oxide Nezvakakuyiwa.

Zvisinei, chinhu chikuru muupenyu application ndiye anogadzira zvinhu thermionic cathodes. Early remakore yokupedzisira, masayendisiti kubva Germany Venelt akadzidza Erekitironi anobuda mutemo, yakanga ichangobva akasvinudzwa Chirungu mupanguri Richardson. For kuedza Venelt akashandisa zvimedu Platinum waya. Yokutanga nemigumisiro experimental zvakazara akasimbisa mhedziso rakavhomorwa gare gare ne Chirungu yefizikisi. Asi zvino ruzivo vakundikana uye Venelt akataura kuti aibuda maerekitironi kwakakwirira zvikuru kupfuura dzose, nokuti pamusoro pemvura kushanda zvinhu - Platinum - aigona kuonekwa chero netsvina. Pashure pokutarira kubvuma kwayo Venelt akawana kuti kwakakura pamusoro Erekitironi panobva kuerera Kutsauka ndiko barium oxide, Platinum chiitiko panyika sechikamu mafuta michina inoshandiswa kuedza namano. Mhedziso Venelta refu akaramba harimboonekwi nokuti masayendisiti vaisagona experimentally bereka ruzivo rwake. Zvakanditorera makore zana anenge kuna Chirungu yefizikisi Kohler akaratidza yakarurama Venelta. Kohler pahwaro akadzokorora kuedza akaratidza kuti kana barium oxide iri pasi kudziyisa panguva zvishoma yakaderera kumanikidzwa, kuti thermionic achine kusimba nokukurumidza inowedzera.

Chete ari thirties okupedzisira remakore, kemisiti yokuGermany Pauro akataura, inoumbwa pakuti maerekitironi vari kusashanda nokuda kuvapo nouipi vari barium oxide. Munguva zvakaitwa, iro inoitwa panguva yakaderera kumanikidzwa, chikamu okisijeni unopukunyuka oxide. Kuramba sezvamakaropafadzwa barium iri ionized uye pakudaro inosimudzira pakuonekwa vakasununguka maerekitironi. maerekitironi izvi uye vaiva avo achisiya crystalline chimiro apo nenharo uye izvo kamwe vakatarira Venelt.

Yakanga chete pakutanga yechipiri yezana remakore rapfuura rakanga pakupedzisira akaratidza kururama kwemashoko pfungwa iyi. MaKemisiti uye P. A. Bundeli Language Kovtun (USSR) aisagona chete dziwande kuisa kukosha wevasungwa nouipi vari barium oxide, asiwo kuedza kuenzanisa kukosha kwayo ane thermionic chokubuda uwandu. Ndokusaka barium oxide inoshandiswa kutoshanda pazvokudya anogadzira zvinhu thermionic cathodes. Somuenzaniso, imwe Erekitironi danda, uhwo vanowanika mufananidzo pamusoro chidzitiro nyore terevhizheni kana kombiyuta Monitor. Unhu rukova panobva pano anoita barium oxide.

Kana fuma iri kuedza mudutu mvura, vakaona kuti barium oxide ikasakendenga nemvura nokuda muchidziisa mhinduro. Saka kuwana fuma barium hydroxide - chena upfu with utsotso zvokusvika 78 ° C. remubatanidzwa iri vakaita pamwe chakanakisisa , carbon dioxide gasi, uye naizvozvo ane aqueous mhinduro, anowanzonzi "barite mvura", rinoshandiswa nevakawanda senzira reagent kuti carbon dioxide.

The kutanga remubatanidzwa uye aida chinoumba kunobatanidzwa dzakashongedzwa coloring zvinhu, lubricants uye mafuta. kushandiswa rwakadaro barium oxide rakafanotaura kunyange Di Mendeleev.
