Bismuth oxide Overview The normal color of bismuth is a yellowish powder. However, it turns orange when heated and then becomes reddish brown after cooling. Bismuthoxide is insoluble, however, in alkali as well water. Each crystal structure of ytrium 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 ytrium-oxide can also vary depending on the crystal type: Monoclinic crystals 8.2 g/cm 3, while Tetragonal Crystals 8.55g/cm 3 cubic crystals 8.9g/cm 3. The monoclinic structure and cubic structures of BiO3 are both low temperature stable phases. Procedure for creating nano-cerium oxygen Presently, there are many ways to make nanocerium oxide. The methods can be categorized as liquid, solid, or gas phases. Researchers have been able to create a wide range of nanoceriumoxides using a number of different morphologies in the last few years thanks to continuous innovation of related technologies. 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 Solid phase preparation is a more traditional method for making powder. The reaction agent is usually used in a liquid phase. It is simple to obtain the necessary conditions, which is why the result is very easy to form an agglomeration. Additionally, the particle size isn’t uniform. 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. Once it reaches a desired temperature, nano-cerium oxide can be made. For example, Hong Weiliang et al. It is important to thoroughly mix the (BiNO ), 35H 2Oand NOH. Once it has been mixed, it should be heated in a bath with a constant temperature of 60°C. This will allow you to obtain a solution following a series if treatments. 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 prepare desired nanomaterials. It involves exposing a substance to an physicochemical react in a liquid 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 particle sizes and a high degree of purity. The reaction conditions can be difficult to regulate and it requires strict equipment. This makes the 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 morphology, material composition, and generally the quality of prepared nanomaterials. This method, however, can be susceptible to impurities and is therefore not appropriate for those applications that require high product purity. It has been possible to create nanomaterials through liquid phase preparations thanks to the advancements in technologies such as ultrasonics, microwave radiation, and ultrasonic methods. You will find many liquid phase methods available, including the freeze-drying or hydrothermal method as well as radiation chemical synthesis and precipitation methods.
