Properties and uses of cuprous oxide

1, Cuprous oxide can be dissolved in hydrochloric acid to generate HCuCl2 (cuprous chloride complex), can also be dissolved in sulfuric acid and nitric acid respectively to form copper sulfate and copper nitrate. 2. Although cuprous oxide is stable in dry air, it will be slowly oxidized in wet air to generate copper oxide, so it can be used as a deoxidizing agent; In addition, it is easy to reduce it to copper with reducing agent. 3, cuprous oxide is insoluble [...]

Properties and applications of nano-sized zinc ferrite

Ferrates of manganese, zinc, cobalt and nickel are important functional materials. Among them, Mn-Zn and Ni-Zn ferrite are the largest high frequency soft magnets in the world, which are commonly used as magnetic materials for high frequency transformers, inductors and recording heads. Ferrate is also an important catalyst, has been used in ammonia synthesis, Fischer-tropsch synthesis, as well as ethylbenzene, butene oxidation dehydrogenation reaction, it has broad application prospects in chemistry and chemical synthesis and other fields. Spinel zinc ferrite [...]

Zinc stannate a flame retardant and smoke suppressor replaces antimony trioxide

Flame retardants and halogen sources act on both flame and smoke in a variety of important polymer systems. Health, safety and the environment are important factors in today’s world, and zinc stannate products have no negative impact in these areas. Zinc stannate is an anhydrous product with excellent thermal stability even at 400 degrees and is recommended for use in polyamide systems. The molecular structure of zinc stannate contains tin and zinc; Both elements have special functions that allow [...]

Role and application of niobium carbide

Niobium carbide is a green cubic crystal with metallic luster, belonging to the sodium chloride cubic crystal system. It has high melting point, high hardness (microhardness 235GPa, harder than corundum), good chemical stability (stable at 1 000~1 100℃, and rapid oxidation into niobium pentoxide above 1 100℃), insoluble hydrochloric acid, sulfuric acid and nitric acid, A mixture of hot hydrofluoric acid and nitric acid soluble only. Niobium carbide is easy to melt in titanium carbide, zirconium carbide, tungsten carbide [...]
