Abstract
An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include silicon dioxide (SiO2) at 25 to 50 wt %; boron oxide (B2O3) at 1 to 15 wt %; one or more of lithium superoxide (Li2O), sodium oxide (Na2O), or potassium oxide (K2O) at 10 to 20 wt %; sodium fluoride (NaF) at 1 to 5 wt %; zinc oxide (ZnO) at 1 to 10 wt %; and one or more of titanium dioxide (TiO2), molybdenum trioxide (MoO3), bismuth oxide (Bi2O3), or cerium dioxide (CeO2) at 20 to 40 wt %, such that a heating time required for cleaning is shortened and cleaning is possible without carrying out a water soaking process.
