Preparation technology of nano bismuth oxide

For the preparation of nano bismuth oxide, the main methods include plasma method, melt spray oxidation method, chemical vapor condensation method, sol-gel method, chemical precipitation method, etc. Each method has its own characteristics. The plasma method has the advantage of short process, but requires special equipment, one-time investment, high cost; Melt spray oxidation process is short, but there are some problems such as incomplete bismuth oxidation, short nozzle life, dangerous operating environment, etc. Chemical vapor condensation method has high [...]

Plasma treatment to improve the quality of nano bismuth oxide

Bismuth oxide is an important functional powder material, widely used in inorganic synthesis, electronic ceramics, chemical reagents and other fields, mainly used in the manufacture of ceramic dielectric vessels, can also be used in the manufacture of piezoelectric ceramics, varistors and other electronic ceramic components. Due to the finer particle size of nanometer bismuth oxide, in addition to the properties and applications of bismuth oxide powder with general particle size, it can also be used in occasions with special particle [...]

The magical use of nano silicon carbide

Cubic silicon carbide, also known as β-SiC, belongs to the cubic crystal system (diamond crystal type), relative to the common silicon carbide powder α-SiC (black silicon carbide and green silicon carbide) has a unique advantage. Research shows that beta SiC powder with wear-resistant, high temperature resistant, heat resistant, corrosion resistance, radiation resistance, good conductive properties such as good performance, can be widely used in the high-grade refractory materials, special ceramics materials, grinding materials and advanced and reinforced material, and other [...]
