Abstract: A glass frit according to this application may include a composition of P2O5, V2O5, TeO2, CuO, ZnO, and BaO configured to replace a conventional lead glass composition and enable a low temperature calcination. A coefficient of thermal expansion (CTE) of the glass frit may be matched with that of a glass substrate. The composition may not include an inorganic filler or at least reduce a content of an inorganic filler to reduce or prevent separation and breakage and to improve durability. The glass frit may be used as a paste for a vacuum glass assembly.

Abstract: Disclosed are a composite glass composition for washing and cleaning and a method for producing composite glass powder using the same, in which a silicate-based glass composition containing an alkali oxide for activating water into alkaline water and a bleaching agent having bleaching performance are mixed or coated. Accordingly, since the silicate-based glass composition containing an alkali oxide can ionize water in place of a surfactant contained in existing synthetic detergents, washing and cleaning capacity equivalent to or greater than existing synthetic detergents can be secured with alkaline water ionized from water.

Abstract: The present invention relates to a glass composition capable of being used as a sealant, and a solid oxide fuel cell using same. The sealant glass composition according to the present invention comprises 10-45 wt % of SiO2, 0.1-20 wt % of B2O3, 40-65 wt % of BaO, 0.1-20 wt % of CaO, and 0.1-15 wt % of at least one of Al2O3 and ZrO2, and unlike existing sealant glass compositions, can be suitably used in solid oxide fuel cells operating at intermediate temperatures, and exhibits an advantageous effect in keeping a decrease in sealing adhesion strength to a minimum, even after prolonged use.

Abstract: 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.

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 phosphorus pentoxide (P2O5); 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 manganese dioxide (MnO2), molybdenum trioxide (MoO3), bismuth oxide (Bi2O3), or nickel oxide (NiO). The enamel composition may be cleaned without being putting it into water.

Abstract: A cooker including a first coating layer that is a general ceramic enamel layer and a second coating layer that includes phosphorus oxide-based components are coated on a surface of a cavity corresponding to the inner surface of the cooking chamber. Therefore, the inside of the cooking chamber can be more easily cleaned.
