In the metallurgy and materials industry, the use of Nb2O5 has continued to increase in recent years, albeit at a small rate. However, its usage is still the largest, the price is lower and more stable, and the requirements of quality standards have not changed much. As competition intensifies, production of Niobium oxide is almost unprofitable. Therefore, ensuring quality and reducing costs is the only way for manufacturers. To reduce costs, there are several suggestions for reference.
Nonferrous metal, Rare metals, Rare And Noble Metal, Metal powder.
Nanometer TiO2 Series, Nanometer SiO2 Series,Nanopowder,Graphene.
Production of tin nanometric powders by hydrogen DC claret arc evaporation.

The mechanical peeling method is a method of obtaining a thin layer of graphene material by utilizing friction and relative motion between an object and graphene. This method is simple to operate and the resulting graphene typically maintains a complete crystal structure.
The internal carbon atoms of graphene are arranged in the same manner as the graphite monoatomic layer by sp2 hybrid orbital, and have the following characteristics: carbon atoms have four valence electrons, and three of them generate sp2 bonds, that is, each carbon atom Contributing to an unbonded electron in the pz orbital, the pz orbital of the neighboring atom forms a π bond in a direction perpendicular to the plane, and the newly formed π bond is semi-filled.
Hydroxylated graphene is a two-dimensional carbon nanomaterial composed of a carbon atom and a sp2 hybrid orbital to form a hexagonal honeycomb lattice.
Cupric nitrate with a chemical formula of Cu(NO3)2 and a molecular weight of 187.56. Blue oblique flaky crystals. Deliquescent. At 170 ° C, liberation of oxygen. Soluble in water and ethanol, almost insoluble in ethyl acetate. The pH of the 0.2 mol/L aqueous solution was 4.0. The relative density is 2.05. The temperature of 114.5 ° C. It is oxidizing, and when it is heated and struck and rubbed with charcoal, sulfur or other flammable substances, a combustion explosion occurs.
1. Add a slight excess of bromine directly to a saturated solution of saturated sodium hydroxide to form a mixture of bromide and bromate:
The mixture at this time is evaporated to dryness, and the obtained solid residue is heated and mixed with carbon powder to reduce the bromate to bromide:
Sodium bromide, a chemical formula of NaBr, is a colorless cubic crystal or a white granular powder. Odorless, salty and bitter. Let me introduce some information about Sodium bromide:
