Q:What is salt oxide, what is not salt oxide?
The salt oxide is the oxide and the corresponding acid and acid ions
Q:Which of the active oxides is good
Is located in the south of Hebei Province Guangzong County Development Zone (under the Xingtai City), OKorder-OKorder high-speed, large high-speed, Jiqinggaosu, Xing Lin high-speed around the four weeks, Han River is rich in resources, the capital of Hebei Province, Shijiazhuang is the seat of the China Magnesium Salt Association, academic research and innovation atmosphere, engaged in magnesium salt R & D and production talent pool, lead Magnesium salt technology pioneer, the plant with advanced technology to soluble magnesium salt and dolomite as raw materials to produce high quality lightweight magnesium carbonate, light magnesium oxide, active magnesium oxide, high purity magnesium oxide, magnesium hydroxide, heavy magnesium oxide professional factory. I plant with complete raw materials, finished semi-finished product testing means, the whole 38 hours of continuous monitoring of the whole process of production, the use of advanced magnesium salt modern production process, continuous composite, decomposition, impurity, synthesis concerned about the production process of every detail, Production of small particle size, high purity, specific capacity, high activity, product quality and stability, the use of good performance, is the perfect substitute for imported magnesium salt products, determined to tree in the new image of magnesium products, widely used in rubber, Such as cable, enamel, ceramics, dyes, pharmaceuticals, military, glass steel, ball polishing, chemical building materials, dyes and pharmaceutical intermediates, composites and other industries. Marketing more than 20 provinces and autonomous regions. Due to good reputation and extensive sales network, Some well-known manufacturers commissioned sales agents other chemical products, SBS792, zinc stearate, titanium dioxide, SBS792,796 (Yueyang production) and other production
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 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:Definition and properties of oxides and basic oxides
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.
Q:The world's strongest oxide
Chlorofluorinated Chloride C1F5 Chlorinated Fluorinated Chloride is a non-combustible, non-combustible colorless gas with strong irritating odor at room temperature. Its solid state is white and has a pale yellow color. It is rapidly hydrolyzed to form chlorine and hydrofluoric acid It is a strong oxidizing agent that reacts strongly with most of the inorganic matter, so that although it does not burn in the air, it can cause fire and explosion.
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.
Q:Iron oxides and their properties
There is iron oxide FeO, black powder, it is unstable, heated in the air, that is quickly oxidized into Fe3O4
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.
