I-phosfite yenziwa kubushushu obuphezulu. Igrafu ixhaphake kakhulu eMarble, i-schist okanye i-Gneiss, kwaye yenziwa yi-metamorphism yezinto eziphilayo ze-carbonaceous. I-Coal Seam inokuthi yenziwe ngokuyinxenye i-graphtite yi-phrogrite yi-itampirphism ye-thermal. Igrafu yeyona minelip yelitye le-IGneous. Igrafu ixhaphakile kwi-meteorites. Kuyinto eqhelekileyo. I-Polycrystaline Agegrestates eyenza ubume be-cubic kunye nolwalamano oluthile lokuqhelaniswa nezifundo lubizwa ngokuba yigrafu yesikwere. Ke siyintoni isizathu sokuba i-flake igrafu ingasetyenziswa njengezinto zokutywina? Le ncwadana ilandelayo ye-furuite i-xiaobian ithatha ukuba wazi ngakumbi ngayo:
I-1. Ukungafani kobugqi, amandla e-thensile asezantsi.
Ukufakwa kwegrafu kunefuthe elibaluleke kakhulu kumgangatho wemveliso weepleyiti, iirhasi zenxeba kunye nokupakisha amakhonkco.
2. Ukuveza.
Ngenxa yomxholo wesalfure kunye nomxholo we-chlorine wegrafu ephambili, ukwakhiwa kuphakamile kakhulu.
I-3. Ixabiso eliphezulu lokuvuza.
Ngenxa yomgangatho wezixhobo eziluhlaza, ukwakhiwa kwe-ash kunye netekhnoloji yemveliso yegrafu ephambili.
