Silicon carbide Wafer Boat o loʻo faʻaaogaina lautele e fai ma faʻamau faʻapipiʻi i le faʻasalalauga maualuga o le vevela.
Tulaga lelei:
Tete'e o le vevela maualuga:fa'aoga masani ile 1800 ℃
Fa'avevela vevela maualuga:e tutusa ma mea graphite
Malosi maualuga:maaa lona lua i taimane, boron nitride
Tete'e a'a:malosi malosi ma alkali e leai se pala i ai, o le corrosion tetee e sili atu nai lo tungsten carbide ma alumina
māmā mamafa:maualalo le mamafa, latalata ile alumini
Leai se deformation: maualalo coefficient o le faalauteleina vevela
Tete'e te'i vevela:e mafai ona tatalia suiga tetele o le vevela, tetee atu i le te'i vevela, ma e mautu le faatinoga
