Estimating the term…
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 superoxide (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.
An enamel composition, comprising:
A method for preparing an enamel composition, comprising:
The method of 17, wherein the spraying of the frit includes directly applying a single layer of the frit onto a steel sheet substrate without using an interposing buffer layer, and wherein the frit is applied to form a coating layer having a thickness of about 80 to 250 μm, and the frit is fired at about 830 to 870° C. for about 300 to 450 seconds.
