Cerium Oxide – What’s it all about?
Cerium oxide is either a pale yellowish-brown or light yellowish powder. The bulk density is 7.13g/cm3, and the melting point at 2397. The 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, catalysts, and fuel cell electrolytes. It also acts as an ultraviolet absorber, fuel cell electrolytes. It can also be used in automobile exhaust absorbers. It can also be used for electronic ceramics.
Antifogging Glass Agent
Wet or rainy weather can make it easy for moisture to form on glass products like building glass, windshields, rearview lenses, spectacle lenses, and more. This is due to humidity. Water droplets that form on glass substrate in the shape and size of small hemispheres can cause a prism-like reflection effect. It also affects visibility and light transmittance. Fogging of glass may cause problems in people’s lives and can even pose a danger to their safety. The visibility of light transmittance 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 many different methods to fix this problem. It is common to use the antifogging technique, which is simple and easily applied. A variety of solvents, surfactants, wetting agents and dispersants have been reported in 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. Researchers are currently comparing the results from adding oxides in anti-fogging agents. 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 good abrasion resistance as well as abrasion and solvent resistance. The next step is SiO2 antifog and TO2/SiO2 compoite film. But, this process can be complicated and harsh.
Nano-cerium Oxide Glass Antifogging Medic
Its special surface effects and volume effects determine the special chemical properties of nanocerium oxide particles and their special effects. This includes enhancing the surface adsorption of nano-cerium oxide particles, showing high chemical reactions activity, increasing specific area and enhancing activity. It also has high catalytic efficiency. 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. It also can absorb ultraviolet light which helps prevent them from rays. Finally, the CeO2 can act as a photocatalyst and can even help the organic material on the glass surface.
A new form of cerium dioxide glass anti-fogging agents with good antifogging effects, long anti-fogging times, stability, safety, harmless and easy 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 then used to produce nano-CeO2 particles.
The Preparation of Nano Cerium Oxide Antifogging Treatment
Use appropriate dispersants, additives or surfactants to combine the antifogging agent. Conduct experiments using the single factor optimization to find the most effective formula.
