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:Oxide and organic peroxide signs

Broad oxide (oxide) refers to the oxygen element and another chemical composition of the binary compounds, such as carbon dioxide (CO?), Calcium oxide (CaO) and so on. But the combination of oxygen and electronegativity with greater fluoride is generally referred to as fluoride rather than oxide.

Q:Clothes on the metal buttons and metal ornaments for a long time there will be a layer of oxide, looks bleak, what good way to make these metal accessories smooth shiny?

Brush with vinegar or toothpaste

Q:What is the largest oxide of oxygen content?

Superoxide

Q:What is called transition metal oxide doping

Transition element refers to a series of metal elements in the d-region of the periodic table, also known as transition metal, including chromium, manganese, iron, cobalt, nickel, copper, zinc and so on are transition metals.

Q:What is the zinc oxide?

Zinc oxide (ZnO), only this one, zinc and oxygen reaction zinc was only +2 price, oxygen-2 price

Q:What is salt oxide, what is not salt oxide?

A salt-forming oxide refers to an oxide which, in general, produces a salt by direct chemical reaction. Most oxides belong to salt-forming oxides.

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:Do not say fluorine gas, it is the strongest element, do not say that electronic anti-matter and current, authority ah

Oxygen is a colorless, almost odorless highly toxic gas, liquefied after the pale yellow. Because of the oxygen at room temperature with the dry air can react quickly to produce nitrogen dioxide and moldy colorless Gas nitrogen trifluoride (fluorine gas at room temperature with the dry air almost no reaction, which can be seen in the oxidation of tungsten fluoride), so usually see the fluoride is a brown odor of brown gas.

Q:How to judge a chemical formula is not an oxide

While KMnO4 KClO3 contains oxygen but not an oxide.
