Specific application of cerium oxide in glass production

Cerium oxide CeO2 overview

Cerium oxide is an inorganic substance with a chemical formula of CeO2, a light yellow or yellow-brown auxiliary powder. Density 7.13g/cm3, melting point 2397℃, insoluble in water and alkali, slightly soluble in acid. At a temperature of 2000° C. and a pressure of 15 MPa, cerium oxide can be reduced with hydrogen to obtain cerium oxide. When the temperature is released between 2000°C and the pressure is released to 5MPa, the cerium oxide is slightly yellow, reddish and pink. Its performance is used for polishing materials, catalysts, catalyst carriers (auxiliary agents), ultraviolet absorbers, fuel cell electrolytes, automobile exhaust absorbers, electronic ceramics, etc.

Specific application of cerium oxide CeO2 in glass production

Used as an additive in the glass industry, as an abrasive material for plate glass, and can also be used in cosmetics to play an anti-ultraviolet effect. At present, it has been expanded to the grinding of spectacle glass, optical lens, and picture tube, which plays the role of decolorization, clarification, and absorption of ultraviolet rays and electron rays in the glass.

Add directly to the batch before melting, stir evenly, and then enter the furnace to melt the glass.

The amount of addition is related to the requirements of glass products. Generally, the addition amount of this kind of metal oxide is between 0.5% and 3%. It is recommended to inquire about some mature glass formulas.

Oxidant. Catalyst for organic reactions. Steel analysis is used as a standard sample of rare earth metals. Redox titration analysis. Decolorized glass. Glass enamel sunscreen. Heat-resistant alloy.

It is used as an additive in the glass industry, as an abrasive for flat glass, and can also be used in cosmetics for anti-ultraviolet rays. It has been extended to the grinding of spectacle glass, optical lenses, and picture tubes, which can decolorize, clarify, and absorb ultraviolet rays and electron rays in the glass.

Rare earth effect

Rare earth polishing effect

Rare earth polishing powder has the advantages of fast polishing speed, high smoothness and long service life. Compared with traditional polishing powder-iron red powder, it does not pollute the environment and is easy to remove from pollutants. Polishing lenses with cerium oxide polishing powder takes 30 to 60 minutes, and the work can be completed in one minute, such as iron oxide polishing powder. Therefore, rare earth polishing powder has the advantages of low dosage, fast polishing speed and high polishing efficiency. It can change the polishing quality and operating environment. Generally, rare earth glass polishing powder mainly uses cerium-rich oxide. Cerium oxide is an extremely effective polishing agent because it can polish glass in two ways at the same time: chemical decomposition and mechanical friction. Rare earth cerium polishing powder is widely used in the polishing of cameras, camera lenses, TV picture tubes, spectacle lenses, etc. There are dozens of rare earth polishing powder factories in my country, and more than ten have hundreds of production scales. Ton. Sino-foreign joint venture Baotou Tianjiao Qingmei Rare Earth Polishing Powder Co., Ltd. is one of the largest rare earth polishing powder plants in my country, with an annual production capacity of 1,200 tons, and its products are sold at home and abroad.

Glass bleaching

All glass contains iron oxide, which can be brought into the glass through the raw materials in the glass composition, sand, limestone and broken glass. There are two forms: one is divalent iron, which makes the glass dark blue, and the other is this trivalent iron, which makes the glass yellow. Decolorization is the oxidation of ferrous ions to ferric iron, because the hue intensity of ferric iron is only one tenth of that of ferrous iron. Then add color supplements to neutralize the color to light green.

The rare earth elements used for glass decolorization are mainly cerium oxide and neodymium oxide. The rare earth glass decolorizer replaces the traditional white arsenic decolorizer, which not only improves the efficiency, but also avoids the pollution of white arsenic. Cerium oxide used for glass decolorization has the advantages of stable high temperature performance, low price, and no visible light absorption.

Stained glass

Rare earth ions are stable and bright in color at high temperatures, and are used to mix into the liquid to make glass of various colors. Rare earth oxides such as neodymium, praseodymium, erbium, and cerium are all excellent glass colorants. When transparent glass containing rare earth colorants absorbs visible light with a wavelength of 400 to 700 nanometers, it presents beautiful colors. These colored glass can be used to make indicator lights for aviation, navigation, various vehicles and various high-end artistic decorations.

Neodymium oxide is added to soda lime glass and lead glass. The color of the glass depends on the thickness of the glass, the content of neodymium, and the intensity of the light source. Thin glass is light pink, thick glass is blue-purple. This phenomenon is called neodymium. Two colors; praseodymium oxide produces a green color similar to chromium; erbium oxide is used in photochromic glass and crystal glass to be pink; cerium oxide and titanium dioxide are used together to make the glass yellow; praseodymium oxide and neodymium oxide can use praseodymium black glass.

Rare earth clarifier

Use cerium oxide instead of traditional arsenic oxide as a glass fining agent to remove bubbles and trace colored elements. The effect is remarkable when preparing colorless glass bottles. The finished product has bright white color, good transparency, and improved glass strength and heat resistance. At the same time, it also eliminates the pollution of arsenic to the environment and glass. To

In addition, adding cerium oxide to daily glass such as architectural and automotive glass and crystal glass can reduce the transmittance of ultraviolet rays. This use has been promoted in Japan and the United States. As the quality of life in our country improves, there will be a better market. Neodymium oxide is added to the glass bulb of the picture tube to eliminate the dispersion of red light and increase the clarity. Special glasses with rare earths include: lanthanum glass has the characteristics of high refraction and low dispersion, and is widely used in the manufacture of various lenses and advanced cameras, camera lenses, especially lenses for high-altitude photography equipment; cerium anti-radiation glass, used in automotive glass and TV glass bulbs: Neodymium glass is used as a laser material and is the most ideal material for manufacturing giant lasers. It is mainly used in controlled nuclear fusion devices.
