Cerium Oxide – What’s it all about?
Cerium oxide is either a pale yellowish-brown or light yellowish powder. The bulk density of Cerium oxide is 7.13g/cm3, and its melting point at 2397. Its boiling point is 3500. The substance is insoluble with water and alkali but somewhat soluble in acids. To make cerium trioxide, heat can reduce cerium oxide to 2000°C at 15MPa. Cerium oxide turns slightly yellowish or reddish if it is exposed to temperatures between 2000°C & 5MPa. Its use It can be used to polish materials, catalysts (auxiliary agents), catalyst carriers, catalyst carrier, ultraviolet absorbers fuel cell electrolytes automobile exhaust absorbers, electronic ceramics etc.
Antifogging Glass Agent
Wet or rainy weather can make it easy for moisture to form on glass products like building glass, windshields, car rearview mirrors and glasses lenses. This is due to humidity. Water droplets that form on glass substrate in the form of small hemispheres can cause a prism-like reflection effect. It also affects visibility and light transmittance. Fogging glass can lead to inconvenience and possibly even death. The visibility of light transmission and mirror imaging will be affected by particles like dust or oil. This is why anti-fogging can be closely linked to both work and personal life.
People use several methods to fix this problem. It is common to use the antifogging technique, which is simple and easily applied. A variety of solvents and wetting agents are used in surfactant antifogging agent. While this anti-fogging agents is relatively easy to make, they are difficult to lose due to water condensation on the glass. The general anti-fog period is between 2-7 days. The current research findings on the addition of oxides to anti-fogging agents are being compared. Photocatalytic TiO2 is one of the most popular anti-fog films. Nano-titanium dioxide can diffuse small water droplets onto the glass surface and create a uniform film. This surface is not susceptible to light scattering fog. It can also maintain high transparency levels without burning. Use safely This anti-fog material is safe. It has excellent abrasion resistance.
Nano-cerium Oxide Glass Antifogging Medic
Its special surface effects and volume effect determine the special chemical properties of nanocerium oxide particles and their special effects. This includes a high level of surface adsorption. It also has high specific surface area and surface activity. The light it emits has both a catalytic and hydrophilic function. An ultrafine CeO2 particle can be added to anti-fogging. This will increase the agent’s surface adsorption. Furthermore, the CeO2 can absorb ultraviolet light which helps prevent UV rays. Finally, the CeO2 can act as a photocatalyst on glass.
A new form of cerium dioxide glass anti-fogging agents with good anti fogging effects, long anti fogging times, stability, safety, harmless and simple production has been developed using nano-rare Earth ceriumoxid as a raw materials.
Add a little cerium oxide to a cup of concentrated HNO3 or H2O2 to dissolve. Prepare a 0.5mol/LCeNO33 aqueous mixture and heat slowly. When the temperature reaches above 180 degrees, it will evaporate to create a brown aerogel. This is used to produce nano-CeO2 powder.
The Preparation Method Of Nano Cerium Oxide Antfogging Agent
Use appropriate dispersants, surfactants, additives, nano-CeO2 and solvents to combine the antifogging agent. The single factor optimization method is used to run experiments to determine which formula yields the most effective.
