The present invention relates to an enamel composition capable of implementing cleaning without swelling using moisture, to a manufacturing method therefor, and to cooking utensils. The enamel composition according to the present invention comprises: 20-60 wt % of PO; 1-20 wt % of SiO; 1-30 wt % of BO; 10-30 wt % of at least one of LiO, NaO, and KO; 10-40 wt % of at least one selected from the group consisting of post-transition metal oxides and transition metal oxides. Therefore, the present invention provides an enamel composition capable of implementing cleaning without swelling using moisture, a manufacturing method therefor, and cooking utensils.

Enamel composition, manufacturing method therefor, and cooking utensils

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.

Enamel composition, method for preparing enamel composition, and cooking appliance

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 (PO); 5 to 20 wt % of one or more of lithium oxide (LiO), sodium oxide (NaO), or potassium oxide (KO); 1 to 5 wt % of one or more of sodium fluoride (NaF), calcium fluoride (CaF), or aluminum fluoride (AlF); 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 manganese dioxide (MnO), molybdenum trioxide (MoO), bismuth oxide (BiO), or nickel oxide (NiO). The enamel composition may be cleaned without being putting it into water.
