| Chemical Preparation: |
Cerium oxide is typically synthesized using cerium nitrate as a base, undergoing a series of reactions to produce the final product. The process is as follows:
|
| Hydrothermal Method: |
The hydrothermal method is a commonly used technique for preparing cerium oxide. The specific steps are as follows:
|
| Oxalic Acid Precipitation Method: | Use either cerium chloride or cerium nitrate solution as the base, balance the pH to 2 with oxalic acid, then introduce ammonia water to create cerium oxalate and let it settle. After heating, filtering, rinsing, and drying at 110°C, the cerium oxalate is calcined at a temperature between 900-1000°C to obtain cerium oxide. |
Note: Producing cerium oxide can involve dangerous chemical reactions. It should be done under professional supervision, using proper equipment and safety precautions.
With cutting-edge spectroscopy techniques like X-ray fluorescence (XRF) and inductively coupled plasma (ICP), we analyze the chemical composition of our powders to quantify the concentrations of cerium and any trace impurities.
Advanced methods like laser diffraction and Dynamic Light Scattering (DLS) enable us to accurately determine particle size and distribution, ensuring the powder meets the specified size range.
Measuring bulk density and tap density aids in comprehending the powders' packing characteristics, crucial for their storage and transportation.
Thermogravimetric Analysis (TGA) tracks the weight reduction of the powder during heating, revealing its moisture content and any volatile compounds. This confirms the cerium oxide powder is dry and devoid of undesirable volatile impurities.
The stability and behavior of cerium oxide suspension in different applications can be affected by its pH level. Zeta potential signifies the stability of colloidal dispersions. A high zeta potential value usually implies excellent stability, crucial for suspension-related applications.
