摘要： An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include phosphorus pentoxide (P 2 O 5 ) at 15 to 50 wt%; silicon dioxide (SiO 2 ) at 10 to 20 wt%; boron oxide (B 2 O 3 ) at 1 to 15 wt%; one or more of lithium oxide (Li 2 O), sodium oxide (Na 2 O), or potassium oxide (K 2 O) at 5 to 20 wt%; one or more of sodium fluoride (NaF), calcium fluoride (CaF 2 ), or aluminum fluoride (AlF 3 ) at 1 to 5 wt%; one or more of magnesium oxide (MgO), barium oxide (BaO), or calcium oxide (CaO) at 1 to 35 wt%; and one or more of titanium dioxide (TiO 2 ), cerium dioxide (CeO 2 ), molybdenum trioxide (MoO 3 ), bismuth oxide (Bi 2 O 3 ), or copper oxide (CuO) at 10 to 25 wt%, such that a heating time required for cleaning may be shortened and oil contaminants may be completely removed.
