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 silicon dioxide (SiO2); 1 to 10 wt % of boron oxide (B2O3); 10 to 20 wt % of at least one of lithium oxide (Li2O), sodium oxide (Na2O), or potassium oxide (K2O); 1 to 5 wt % of sodium fluoride (NaF); 1 to 10 wt % of zinc oxide (ZnO); and 20 to 50 wt % of at least one of titanium dioxide (TiO2), molybdenum oxide (MoO3), bismuth oxide (Bi2O3), cerium dioxide (CeO2), manganese dioxide (MnO2), or Iron oxide (Fe2O3), which provides an enamel composition with a reduced cleaning time, and facilitates cleaning without soaking in water.
Claims13
A method for preparing an enamel composition, comprising:
- providing materials for the enamel composition, comprising:
- 15 to 50 percent by weight (wt %) of silicon dioxide (SiO2);
- 1 to 10 wt % of boron oxide (B2O3);
- 10 to 20 wt % of at least one of lithium oxide (Li2O), sodium oxide (Na2O), or potassium oxide (K2O);
- 1 to 5 wt % of sodium fluoride (NaF);
- 1 to 10 wt % of zinc oxide (ZnO);
- 10 to 30 wt % of at least one of titanium dioxide (TiO2), manganese dioxide (MnO2), or Iron oxide (Fe2O3) and 10 to 20 wt % of molybdenum oxide (MoO3), bismuth oxide (Bi2O3), and cerium dioxide (CeO2) in total, wherein the enamel composition is a silicate-based glass composition;
- melting the materials;
- and
- quenching the melted materials to form the enamel composition.
The method of 10, 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.
