Bismuth oxide overview Bismuth is a yellowish powder that is normal at temperature. However, it turns reddish when heated and then becomes orange. This color will continue to warm to the point where it is still pale yellow upon cooling. Bismuthoxide is insoluble and insoluble under alkali and in water. But, it can be reduced in acid to form the phosphonium salicylate. Each crystal structure of yttrium oxide is different. A phase composition is a factor that can affect the band width. This means the band space of the phase is 2.85eV but the band span of the Phase is 2.58ev. The density ytriumoxide varies depending on the crystal type: Monoclinic Crystals have an 8.2 gcm 3; tetragonal Crystals are 8.55gcm 3 with cubic crystals that are 8.9gcm 3. The monoclinic structure with BiO3 is a phase that is low temperature stable, while the cubic structure with BiO3 has a higher temperature stability phase. Procedure for making nanocerium oxide Presently, there are many ways to make nanocerium oxide. The methods can be categorised as solid phase (gas phase), liquid phase (liquid phase) or mixed phase (solid phase). Researchers have been able to create a wide range of nanoceriumoxides using a number of techniques that are constantly improving. While the overall performance hasn’t been as impressive as the ones before, its potential applications have increased. We will now briefly discuss the preparation procedures of nanocerium oxide using three methods. (1) Solid phase method The solid phase method for preparation of powder is very traditional. It involves the reaction reagent being reacted in a liquid phase. This allows the reactions conditions to be easy achieved and makes it relatively simple to create agglomeration. This is a popular preparation option in many industrial production areas. The preparation of nanoceriumoxide is usually done by mixing different materials, grinding them, and then calcining. After a time, you can obtain the desired nano-cerium dioxide material. For example, Hong Weiliang et al. It is important to thoroughly mix the (BiNO 5H 2Oand NOH), then grind the powder and heat in a bath for 60 minutes. This will allow you to obtain a solution following a variety of processes. A nano cerium oxide solution is required with a polygonal shape, and 60 nm particles. (2) Gas phase method The gas phase technique is used to make a desired nanomaterial. It involves exposing a substance to an physicochemical react in a gaz state. Gas phase methods are suitable for making nano powders, as they can be carried out at high temperatures. It produces small, fine-grained products with low purity and light agglomeration. The reaction conditions can also be difficult to regulate and strict equipment requirements make this method challenging. Important gas phase method, spray-combustion. In essence, metal is heated in order to melt and create an aerosol. The reaction furnace then produces a strong oxygen reaction by burning fine objects. For example, Kim et al. B-Bi2O3 nanites with diameters between 30 and 90 nanometers at certain temperatures were successfully synthesized. They created a BiO3 films-like structure. (3)Liquid phase method Nanomaterial preparation methods using liquid phases are the most advanced and widely applicable. The liquid phase can selectively prepare nanomaterials that have different microscopic structure and composition. In general, it is very uniform. Unfortunately, there is a risk of accidentally introducing contaminants to the preparation. It is therefore not recommended for use in applications that require high purity. It has been possible to create nanomaterials through liquid phase preparations thanks to the advancement of technologies like microwave radiation or ultrasonics. There are several types of liquid-phase methods available, including: freeze-drying technique, hydrothermal and radiation chemical synthesis techniques, precipitation method.
