Lanthanum Hexaboride

Nkọwa dị mkpirikpi:

Lanthanum Hexaboride (LaB6,A na-akpọkwa lanthanum boride na LaB) bụ kemịkalụ inorganic, boride nke lanthanum. Dị ka ihe seramiiki refractory nke nwere ebe na-agbaze nke 2210 Celsius, Lanthanum Boride bụ ihe na-adịghị edozi ahụ na mmiri na hydrochloric acid, na-atụgharị na oxide mgbe ọ na-ekpo ọkụ (calcined). Ihe nlele Stoichiometric na-acha odo odo-violet, ebe ndị bara ọgaranya boron (n'elu LaB6.07) na-acha anụnụ anụnụ.Lanthanum HexaborideA maara (LaB6) maka isi ike ya, ike arụ ọrụ, ikuku thermionic, yana ihe plasmonic siri ike. N'oge na-adịbeghị anya, e mepụtara usoro sịntetịtịk ọkpụkpọ okpomoku ọhụrụ iji rụpụta nanoparticles LaB6 ozugbo.
