Learn details of nano bismuth oxide common application fields

Common applications of nanometer bismuth oxide is a kind of important functional materials, bismuth oxide has a very wide range of applications. It is not only a good organic synthesis catalyst, ceramic colorant, plastic medicinal astringent, glass additives, flame retardants, high refractive glass and glass of nuclear engineering and nuclear reactor of the fuel,  but also it is an important doping powder material in the electronic industry.

Bismuth oxide various application fields

Electronic functional material  

Bismuth oxide powder, as a kind of electronic functional powder doping material, is widely used in the production of sensitive components, dielectric ceramics and other electronic components. It has the characteristics of high quality, small quantity and wide range.  Under normal conditions, alpha-bismuth oxide with monoinclined structure is the most stable, and its crystal structure contains a large number of oxygen vacancies, and oxygen ions have good conductivity, which can be used to make various solid oxide fuel cells and oxygen sensors.  Bismuth oxide is also an active substance commonly used in chemical power sources, such as an excellent corrosion inhibitor for mercury-free zinc batteries, an electrode material for lithium batteries, and an additive to improve the rechargeable performance of alkaline zinc-Manganese dioxide batteries.  It was found that the nanoscale bismuth oxide had better rechargeable performance than the conventional bismuth oxide powder, and as an additive of the active material EMD of the positive electrode of primary battery, it showed excellent performance under deep discharge.

Burning rate catalyst

Lead oxide is an important catalyst for burning rate of double base solid propellants, which can increase the burning rate of propellants and reduce the pressure index. However, lead is more toxic and has direct or potential harm to people or the environment.  Bismuth is a low toxicity, little smoke, and extremely ecological.

Bismuth is a safe burning rate catalyst.  Nano bismuth oxide has better burning rate of propellant than nano lead oxide at low pressure, and nano bismuth oxide has a bright future in replacing nano lead oxide.

Photocatalytic degradation of materials  

It is reported that bismuth oxide photocatalytic treatment of wastewater containing nitrite has good photocatalytic activity.  Due to large specific surface area and high photocatalytic activity, nanomaterials show better photocatalytic properties.  

Radiation-proof material  

Current radiation protection materials are generally made with lead, which is harmful both to the human body and the environment.  Bismuth is a kind of "green metal", and the ray attenuation coefficient of bismuth is larger than that of lead. If the strong radiation resistance of bismuth oxide is combined with the quantum effect of nanomaterials, it is undoubtedly a new way to develop high performance radiation protection materials.
