Abstract

An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include phosphorus pentoxide (PO) at 15 to 50 wt %; silicon dioxide (SiO) at 10 to 20 wt %; boron oxide (BO) at 1 to 15 wt %; one or more of lithium oxide (LiO), sodium oxide (NaO), or potassium oxide (KO) at 5 to 20 wt %; one or more of sodium fluoride (NaF), calcium fluoride (CaF), or aluminum fluoride (AlF) 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), cerium dioxide (CeO), molybdenum trioxide (MoO), bismuth oxide (BiO), 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.
