Diversified Applications and Technical Advantages of Antimony Compounds in Petrochemical Industry
Innovative applications and functional enhancement of antimony
compounds in the glass industry
- Antimony oxides (such as antimony pentasulfide and antimony trioxide) can be used as yellow colorants for glass, giving it a bright color. At the same time, antimony trioxide can also be used as a decolorant to improve the transparency of glass by neutralizing the green hue caused by iron impurities.
- Antimony trioxide is used in combination with nitrates to release oxygen at high temperatures, effectively eliminating bubbles in the glass melt. For example, sodium antimonate and hydrated sodium antimonate are commonly used clarifiers in the production of cathode ray tube glass shells and optical glass.
- Antimony compounds can improve the impact resistance and heat resistance of glass, extending its service life. In glass-ceramics, antimony can also adjust the thermal expansion coefficient and surface tension, optimizing processing properties.
Special functions and application expansion of antimony
compounds in ceramic industry
Antimony compounds (such as antimony pentasulfide) can enhance the lubricity of glazes, making them easier to apply evenly to the surface of the body and improving production efficiency.
At the same time, antimony oxide acts as an opacifier to increase the whiteness and hiding power of the glaze.
Titanium yellow series pigments: Antimony oxide combined with titanium dioxide and chrome green can be mixed to produce tones ranging from beige to orange, replacing the expensive rare earth praseodymium yellow.
Antimony tin gray pigment: Antimony oxide and tin oxide form a stable crystal form, which is used for retro tiles and high-temperature resistant daily porcelain. The blue value increases with the increase of antimony purity.
Antimony furnace slag can replace traditional chemical oxides to produce colored glazed tiles, reducing costs by 50% while meeting performance standards, thereby achieving efficient utilization of industrial waste slag.
