▲Prevent cracking of enamel:it can improve themelting degree of ceramic glaze,reduce the sinteringtemperature,and prevent cracking of enamel.
▲Improve color brightness: can be used as an additive to the pigment, added to the ceramic glaze to improve the color brightness and gloss.
▲Promoting sintering: sodium nitrate plays the role of flux in the sintering process of ceramic materials, which can reduce the sintering temperature of ceramic materials, accelerate the sintering speed, and improve the density and strength of ceramic products.
Sodium nitrate exhibits strong oxidizing properties, used in ceramic glaze formulation to enhance pigment coloration and oxidation, improving the color of metal oxides in glazes.
Sodium nitrate can adjust the reduction and oxidation properties of glazes, balancing the pigments in glazes to achieve the desired color effects.
Through its oxidation action, sodium nitrate can assist in impurity removal in glazes, enhancing glaze quality and transparency.
Sodium nitrate aids in accelerating glaze melting, lowering the melting temperature, making glazes more flowable during firing, ensuring even coverage on ceramic surfaces.
