Pengaruh Doping Logam Fe pada CaF2 terhadap Struktur Ca1-xFexF2

Abstract

Pada penelitian ini dilakukan sintesis padatan CaF₂ dan Ca_1-xFe_xF₂ (x= 0,025; 0,05; 0,075; 0,1 dan 0,15) melalui metode sol-gel dan dikarakterisasi struktur padatan dengan difraksi sinar-X. Difraktogram CaF₂ hasil sintesis menunjukkan bahwa katalis Ca_1-xFe_xF₂ memiliki struktur kristal CaF₂, yaitu kubus. Difraktogram padatan Ca_1-xFe_xF₂ menunjukkan adanya pengaruh doping logam Fe terhadap intensitas puncak dan adanya kapasitas doping pada CaF₂ yang ditandai dengan munculnya puncak Fe₂O₃ pada doping 0,15 mol Fe.
