Q:Why can't aluminum and other metals be heated in an electromagnetic oven?

Aluminum and copper are the resistance of magnetic materials, electromagnetic induction heating can not, so, this is common sense of ordinary people to understand it. Xiamen Xin Rui has customers using electromagnetic heater melting aluminum, molten copper, molten gold, experienced, you can draw on

Q:What does "productive scrap metal recycling" mean?

Productive scrap metals include:(I) scrap iron and steel;(two) waste alloy steel(three) scrap non-ferrous metals;(four) waste rare metals

Q:How to extract noble metals from waste electronic products

Advantages and disadvantages of noble metal extraction by flame metallurgy process:Although the technology of extracting noble metals by means of metallurgy has many advantages, such as simplicity, convenience and high recovery rate, there are many disadvantages:1. Burning adhesives and other organic substances on printed circuit boards will produce a large amount of harmful gas and cause two pollution;2, a large number of scum emissions increased by two times solid waste, and at the same time, residue in the residue of some useful metal industry was discarded together; 3, this method can only recover some precious metals, other non-ferrous metals recovery rate is low;4, energy consumption, processing equipment expensive, economic benefits are not high.

Q:Will the metal ions in the layered composite metal oxides be replaced by other ions?

Are generally ionic compounds, namely active metal loses electrons form positively charged cations, and non metal electronic form negatively charged anions, cations and anions by electrostatic interaction to form ionic compounds.

Q:What metal has the fastest heating?

Common metal conductivities: Silver 429 W/mK copper 401 W/mK gold 317 W/mK aluminium 237 W/mK pure iron 36

Q:Are iron and steel nonferrous metals?

Iron, manganese and chromium are ferrous metals, and other metals are nonferrous metals.More importantly, both non-ferrous metals and ferrous metals are within the limits of purity. Steel is an alloy of carbon and iron, a mixture, an alloy, and not a metal.What we commonly call iron and steel is steel. It is not a non-ferrous metal.

Q:What does "active metal" mean?

Second, understand the lively nature of metals:1. the intensity of the reaction with oxygen.2. the intensity of the reaction with the acid.3. is the metal able to displace other metals from the solution of their compounds?.4. whether it can displace hydrochloric acid, hydrogen in dilute sulfuric acid.The more active metals themselves tend to lose electrons and undergo oxidation reactions, and their potential is lower.

Q:What is a metal without magnetism?

Ferromagnetic metals, in general, are metals that attract magnets, including iron, cobalt, nickel, some rare earth metals, and their alloys. In addition to their other metals, such as copper, aluminum, magnesium, zinc and so on, basically can not be attracted by magnets. Therefore, simply from the magnetic, can not immediately determine what this is the metal.

Q:Does the heavy metal solution dilute with the support electrolyte?

When plating, the coating metal or other insoluble material is used as an anode, the workpiece to be plated is used as the cathode, and the cation of the coating metal is reduced to form a coating on the surface of the workpiece to be plated. In order to eliminate the interference of other cations and make the coating even and solid, the solution containing the coating metal cation is used as the electroplating solution so as to keep the concentration of the metal cation of the coating unchanged. The purpose of electroplating is to deposit a metal coating on the substrate to change the surface properties or sizes of the substrate. Electroplating can enhance the corrosion resistance of metal (coating metal uses corrosion resistant metal), increase hardness, prevent wear, improve conductivity, smoothness, heat resistance and surface beauty.

Q:Are there any metals that do not conduct electricity?

But it is not necessary to make all kinds of materials according to modern technology, such as nano materials. It is seen that there is no electrical metal.
