Abstract

An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include phosphorus pentoxide (P 2 O 5 ) at 15 to 50 wt %; silicon dioxide (SiO 2 ) at 10 to 20 wt %; boron oxide (B 2 O 3 ) at 1 to 15 wt %; one or more of lithium oxide (Li 2 O), sodium oxide (Na 2 O), or potassium oxide (K 2 O) at 5 to 20 wt %; one or more of sodium fluoride (NaF), calcium fluoride (CaF 2 ), or aluminum fluoride (AlF 3 ) 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 2 ), cerium dioxide (CeO 2 ), molybdenum trioxide (MoO 3 ), bismuth oxide (Bi 2 O 3 ), 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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An enamel composition, comprising:
 phosphorus pentoxide (P 2 O 5 ) at 15 to 50 wt %;   silicon dioxide (SiO 2 ) at 10 to 20 wt %;   boron oxide (B 2 O 3 ) at 1 to 15 wt %;   one or more of lithium superoxide (Li 2 O), sodium oxide (Na 2 O), or potassium oxide (K 2 O) at 5 to 20 wt %;   one or more of sodium fluoride (NaF), calcium fluoride (CaF 2 ), or aluminum fluoride (AlF 3 ) 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 2 ), cerium dioxide (CeO 2 ), molybdenum trioxide (MoO 3 ), bismuth oxide (Bi 2 O 3 ), or copper oxide (CuO) at 10 to 25 wt %, wherein when both the MoO 3  and the Bi 2 O 3  are included, any one of the MoO 3  or the Bi 2 O 3  is included at 2 wt % or less.   
     
     
         2 . The enamel composition of  claim 1 , further comprising:
 aluminum oxide (Al 2 O 3 ) at 1 to 20 wt %;   zirconium dioxide (ZrO 2 ) at 1 to 5 wt %; and   
       one or more of tin oxide (SnO) or zinc oxide (ZnO) at 1 to 10 wt %.
