I-Lanthanated tungsten yi-oxidized lanthanum doped tungsten alloy, ehlelwa njenge-oxidized enqabileyo umhlaba we-tungsten (W-REO).Xa i-lanthanum oxide esasaziweyo yongezwa, i-lanthanated tungsten ibonisa ukunyanzeliswa kobushushu, i-thermal conductivity, ukumelana nokunyuka, kunye nobushushu obuphezulu be-recrystallization.
