Estimating the term…
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.
An enamel composition, comprising:
A method of preparing an enamel composition, comprising:
The method of 18, 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 600 to 900° C. for about 100 to 450 seconds.
