Application of chrome ore powder in glass industry
The application of chromium ore powder in the glass industry is mainly reflected in its use as a colorant. The following is an introduction to its detailed application:
1. Application principle
The chromium element in chrome ore powder reacts chemically with other components in the glass at high temperatures to form a specific color. This reaction is based on the chemical properties of the element chromium, making chrome ore powder an effective glass colorant.
2. Application fields
Manufacturing of colored glass products: Chrome ore powder can add rich colors to glass products and is widely used in the manufacturing of colored glass products.
Container glass coloring: Specific application scenarios include container glass such as beer bottles, wine bottles, soda bottles, etc. These products usually use green glass because green glass is more resistant to the penetration of ultraviolet rays than colorless glass, thereby protecting the product from light and maintaining the quality and safety of the product.

4. Advantages of chromium ore powder
High refractory temperature: The melting point of natural chromium ore is about 2150°, and the sintering temperature is 1850°. As a glass pigment, it can withstand the high temperature of a glass furnace without changing its performance.
Excellent thermodynamic properties: Chromium ore powder has good thermal conductivity and thermal shock resistance, which can quickly dissipate heat and prevent sintering bursts and casting crack defects.
Good chemical stability: Chromium ore powder shows good chemical stability at room temperature and high temperature, is easy to react with other chemicals, and can maintain a short service life in complex industrial environments.
