Abstract: An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include 15 to 50 wt % of phosphorus pentoxide (P2O5); 1 to 20 wt % of silicon dioxide (SiO2); 1 to 20 wt % of boron oxide (B2O3); 5 to 20 wt % of one or more of lithium superoxide (Li2O), sodium oxide (Na2O), or potassium oxide (K2O); 1 to 5 wt % of one or more of sodium fluoride (NaF), calcium fluoride (CaF2), or aluminum fluoride (AlF3); 1 to 35 wt % of one or more of magnesium oxide (MgO), barium oxide (BaO), or calcium oxide (CaO); and 5 to 30 wt % of one or more of titanium dioxide (TiO2), vanadium pentoxide (V2O5), molybdenum trioxide (MoO3), or iron oxide (Fe2O3). With such an enamel composition, cleaning may be performed at a low temperature for thermal decomposition, and contaminants, such as fat, may be more completely removed.

Abstract: An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include phosphorus pentoxide (P2O5) at 15 to 50 wt %; silicon dioxide (SiO2) at 10 to 20 wt %; boron oxide (B2O3) at 1 to 15 wt %; one or more of lithium oxide (Li2O), sodium oxide (Na2O), or potassium oxide (K2O) at 5 to 20 wt %; one or more of sodium fluoride (NaF), calcium fluoride (CaF2), or aluminum fluoride (AlF3) 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 (TiO2), cerium dioxide (CeO2), molybdenum trioxide (MoO3), bismuth oxide (Bi2O3), 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.
