Description of Bismuth Oxide Powder
Various spectroscopic techniques were used to analyze bismuth oxide particles. They include energy-dispersive X-ray spectroscopy diffuse reflection spectroscopy Fourier transform infrared spectroscopy, UV-visible spectrophotometer. The size, morphology, and UV protection properties that bismuth oxide nanoparticles possess were examined.
Bismuth oxide nanoparticles are synthesized using green process of synthesis. The synthesis was conducted using Mentha pulegium powder. The green synthesis technique has been the subject of much interest in recent years. There is a great potential for this technique in the cosmetic and pharmaceutical industries.
Bismuth oxide nanoparticles showed absorption levels in the 200-400 nm range. This is because of the formation of a bismuth oxide polymorph. Bismuth oxide nanoparticles also exhibited UV blocking abilities. The nanoparticles possessed antibacterial activity.
Bismuth oxide powder was prepared using a straightforward combustion technique. The powder was then dried under vacuum. The surface morphology was evaluated by FE-SEM. The atomic number of bismuth oxide was 2.7 eV.
The calcination time for superfine bismuth oxides with high purity was 612 hours. The temperature for calcination ranged between 450 and 600°C. The particle sizes of the powders range which range from 0.1-0.5 mm.
The band gap energy of bismuth oxide powder was measured through plotting the UV-DRS spectrum. This energy band gap of bismuth powder is 2.7 EV.
Bismuth oxide nanoparticles demonstrated antibacterial activity against Gram-negative and Gram-positive bacteria. The UV protection properties were studied using diffuse reflection spectroscopy. Optimum time for synthesis of nanoparticles was also determined using UV-Visible spectrophotometers and Fourier change infrared-spectroscopy.
Bismuth oxide nanoparticles possessed good dispersibility. The UV protective properties of bismuth oxide nanoparticles are due to the dynamic light scattering property for the tiny particles. The bismuth oxide powder features excellent purity and dispersibility, which is suitable for use in the electronic industry.
Synthesis Bismuth Oxide Powder
There are a variety of methods used for the creation of bismuth powder. The hydrothermal method is one of the methods. It produces powders that have crystallized quality that is high.
Spray pyrolysis is another method for making bismuth oxide powder. It has been employed in many applications like gas sensing applications. Electrospinning is also been used for the production of nanofibers. Sol-gel is yet another method for producing powders that have very narrow pore distribution.
The basic distributions of the bismuth crystal were observed using the scanning electron microscope. A crystallized structure was confirmed by X-ray diffraction. Multiple spectroscopic techniques like dynamic light scattering and FT-IR, XRD and UV-Visible spectroscopy were employed to study the samples.
The spectrum of absorption of UV-visible light was investigated to assess the UV protective properties of the nanoparticles. The wavelength of absorption for UV ranges between 250 and 700 nanometers. The absorption peak of bismuth oxide lies at 229 nm.
The antibacterial property of nanoparticles was also studied using the method of disk diffusion. The antibacterial capability of bismuth oxide was tested on salmonella ATCC 1231. The discs were stained with various concentrations of the samples. The area of inhibition was measured using a ruler.
The green synthesizing of nanoparticles has received much attention in recent time. It is being used for various applications in pharmaceutical industry as well as the food industry.
Bismuth oxide nanoparticles can also be used to block UV light. They are of high purity and are beneficial for antibacterial activity. The photocatalyst made of bismuth oxide has an extensive absorption spectrum it is capable of removing organic molecules. It is also useful in water treatment.
Applications of Bismuth Oxide Powder
Some of the many uses for bismuth oxide powder are surface treatment products, plastics and coatings. The powder is also a significant role in chemical vapor of deposition as well as thermal evaporation, the electron beam process, and.
Bismuth oxide nanoparticles have been investigated as radiosensitizers. Radiosensitizers can enhance the effect radiation on cell viability. This results in damage to DNA of the cells.
Nanoparticles produce high-surface area which can be used to target image. They also display a high radiopacity. Bismuth oxide nanoparticles are utilized in a variety devices, such as surgical devices, optical filters along with magnetic field sensors. They are also used for tracking bismuth accumulation.
Bismuth oxide nanowires with good crystalline quality have been manufactured through the process of induced stress using low temperatures. The materials have been used as radiosensitizers during Megavolt as well as Kilovolt radiative therapy.
Nanostructured bismuth has attracted plenty of interest due to the quantum behaviour of the material. They can also be used in thermoelectric coolers, as well as optical devices.
Bismuth oxide is also proven to be effective as a biological agent. Bismuth base medical formulations are utilized to treat stomach problems. Bismuth is also utilized for astringents in addition to bacteriostatic compounds and refrigerants. It is also used in nuclear industry as a refrigerant. It can also be used as a substitute for lead in electrical equipment.
Bismuth has been utilized for a wide range of purposes from the 19th century onward. However, use of bismuth was slowed in the latter half of 20th century. This was due in part to reversible bismuth encephalopathy. However, there's a a number of established treatments that require the latest technologies.
