Q:What is the oxide: Elements and oxygen compounds are called oxides (and only two elements). Such as carbon dioxide (CO2), calcium oxide (CaO) Depending on the chemical nature of the oxide, the oxide according to whether the formation of salt with water and the type of salt can be divided into acidic oxides, alkaline oxides, amphoteric oxides and non-salt oxides [1] four categories. There are also many complex oxides.

Q:What is the zinc oxide?: Zinc oxide is an oxide of zinc. Hard to dissolve in water, soluble in acid and alkali. Zinc oxide is a commonly used chemical additive, widely used in plastic, silicate products, synthetic rubber, lubricants, paint coatings, ointment, adhesives, food, batteries, flame retardants and other products in the production. Zinc oxide band gap and exciton greater binding capacity, high transparency, excellent room temperature luminescence performance in the semiconductor field of liquid crystal display, thin film transistors, light-emitting diodes and other products are used. In addition, the micro-particles of zinc oxide as a nano-materials also began to play a role in related areas.

Q:Oxide and organic peroxide signs: An organic compound containing -O-O-peroxy functional group formed by replacing hydrogen atoms in hydrogen peroxide with an organic group such as an alkyl group, an acyl group, an aromatic group or the like. Characterized by heating more than a certain temperature will decompose to produce oxygen free radicals, unstable, easy to break down. Chemical production of organic peroxides is mainly used for synthetic resin polymerization initiator, catalyst. In the field of polymer materials, it can be used as a radical polymerization initiator, graft reaction initiator, rubber and plastic cross-linking agent, unsaturated polyester curing agent and spinning grade polypropylene in the preparation of molecular weight and Molecular weight distribution regulator. Environmental pollution in the air under the action of light through the free radical reaction can produce peroxy nitrates compounds, photochemical oxidants in one of the species. On the skin, eyes, mucous membrane has a strong irritant, is an important pollutant in the atmosphere. Such substances are flammable and explosive dangerous goods, the use should pay attention to safety. Generally, the active oxygen content, activation energy, half-life and decomposition temperature were used as the basis of selection.

Q:Acidic oxide is a kind of oxide which can form acid or react with water to form salt and water. Generally non-metallic elements of oxides and certain transition metal elements of high-priced oxide. Such as sulfur trioxide SO3, phosphorus pentoxide P2O5, manganese dioxide Mn2O7, chromium trioxide CrO3 and so on. Most of the non-metallic oxides are acidic oxides. In our familiar non-metallic oxides, carbon monoxide and nitric oxide are not acidic oxides, and are usually classified as non-acid oxides.: The corresponding hydrate of the basic oxide is a base. For example, CaO corresponding to the hydrate is Ca (OH) 2, Fe2O3 corresponding to the hydrate is Fe (OH) 3.

Q:What is called transition metal oxide doping: The so-called dopant oxide is doped with impurities in oxides, such as the incorporation of trivalent Al in ZnO, and the doping of oxides can affect and alter the original properties.

Q:Titanium oxide total of several?: Ti2O3 titanium dioxide purple powder, hexagonal crystal structure, lattice constant α = 0.5155nm. Containing oxygen 59.5% ~ 60.8% (at). Density 4.486g / cm3. Melting point 1900 ℃. Soluble in 40% Hydrofluoric acid, can be concentrated nitric acid erosion, but not concentrated hydrochloric acid, concentrated sulfuric acid erosion, nor for alkali erosion, and 30% (mass) hydrogen peroxide solution to produce a slightly yellow solution. ~ 300 ℃ into titanium pentoxide. Vacuum in 1600 ℃ heated titanium powder and titanium dioxide mixture or 1500 ℃ hydrogen reduction of titanium dioxide. Titanium ion itself is an excellent reducing agent.

Q:What is salt oxide, what is not salt oxide?: The salt oxide is the oxide and the corresponding acid and acid ions

Q:Whether the metal oxides are alkaline oxides: Alkaline oxides are metal oxides

Q:Is SiO2 an amphoteric oxide?: Not though SiO2 reacts with HF but the reason for this reaction is not because H + is because Si and F-coordination generated SiF4 is very stable.

Q:What is the largest oxide of oxygen content?: [Hydrogen peroxide] pure hydrogen peroxide is a light blue viscous liquid, can be any proportion of mixed with water, is a strong oxidant, aqueous solution commonly known as hydrogen peroxide, colorless transparent liquid. The aqueous solution for medical wound disinfection and environmental disinfection and food disinfection. Under normal circumstances will be broken down into water and oxygen, but the decomposition rate is extremely slow, speed up its reaction rate is to join the catalyst - manganese dioxide or with short-wave radiation.
