The invention provides
nickel oxide high-temperature purple silk-gloss
ceramic glaze and a preparation method thereof, and belongs to the field of
ceramic. The
nickel oxide high-temperature purple silk-gloss
ceramic glaze is obtained by firstly preparing a
nickel oxide high-temperature purple silk-gloss
ceramic glaze material, and then
glazing and
sintering at high temperature, wherein the nickeloxide high-temperature purple silk-gloss
ceramic glaze material is prepared from the following raw materials according to the
mass percent of each
raw material: 45 percent to 35 percent of
potassium feldspar powder, 4.5 percent to 6 percent of
silicon dioxide, 4.5 percent to 10 percent of kaolin, 10 percent to 20 percent of
zinc oxide, 30 percent to 40 percent of a
frit and 1 percent to 2 percentof
nickel oxide. The
frit is prepared from the following raw materials according to the
mass percent of each
raw material: 1 percent to 3 percent of
potassium oxide, 12 percent to 20 percent of sodiumoxide, 2 percent to 8 percent of
calcium oxide, 10 percent to 35 percent of
barium carbonate and 40 percent to 60 percent of
silicon dioxide. By adopting the method provided by the invention, a phenomenon in a firing process of a traditional
glaze material that a lot of poisonous heavy
metal is volatilized is overcome; meanwhile, phenomena that needle holes and cracks are formed in the surface ofa fired product are effectively prevented.
