Platite plate (graphite boat) faʻatamaia le maualuga-lelei graphite mea, faʻaopopoina mea totoʻa faʻatasi ma le malosi acid tetee. E faʻaleleiina e le maualuga-mamafa faʻatupuina, lagona gaogao impregnation, ma maualuga-vevela vevela togafitiga. E i ai tulaga ese acid ma vevela tetee. O se mea lelei e ufiufi ai mea mo vailaʻau o tali atu o le acid phosphoric ma tane teuina o le acid phosphoric i le vailaʻau vailaʻau. O le oloa i ai le uiga o le laei teteʻe, vevela teteʻe, teteʻe teteʻe, corrosion tetee, tolotolo teteʻe, suauʻu-leai-o oe lava-lubrication, laititi faʻalauteleina coefficient, ma sili atu faʻamaufaʻailogaina gaioiga.
