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 not easily soluble or soluble with alkali and water. However, it is slightly solubilized in acid. 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 & 5 MPa. It can be used to polish materials, catalysts (auxiliary agents), catalyst carriers, catalysts, and fuel cell electrolytes. It also serves as an ultraviolet absorber, fuel cell electrolytes. It can also be used in automobile exhaust absorbers. It can also be used to make electronic ceramics.
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 shape 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 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. At the moment, there are no comparisons between the results of 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 compovid 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, increasing chemical reaction activity and surface active centres, as well as increasing surface activity. It also has high catalytic performances. 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.
A new form of cerium dioxide glass anti-fogging agents with good antifogging effects, long antifogging 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 solution. Then, heat it to 180°C. A large quantity of brown aerogel can be formed and then burned to create nano-CeO2 particles.
The Preparation Method Of Nano Cerium Oxide Antfogging Agent
Use appropriate dispersants, additives or surfactants to combine the antifogging agent. Conduct experiments using the single factor optimization to find the most effective formula.
