Q:Method for identifying iron powder, aluminium powder and graphite powder

1. aluminum powder is silver, black substance attract rest with a magnet that attracted iron, not be attracted to the graphite2. Add equal mass, such as concentration of dilute hydrochloric acid, the gas is fast aluminum powder, slow iron, and do not produce gas is graphite.

Q:Graphene with graphite powder where to do ah, high carbon content of the?.

Look at the document, 45 microns will do. Good to buy. Preferably expanded graphite. But then again, if you buy graphite as graphene... The difficulty is not small

Q:Which shipping company can pick up the name of graphite? Graphite products are mainly exported to India, Italy and the United states!

Graphite is neither a liquid nor a dangerous substance. There is no excuse for not answering it.

Q:Two simple physical methods are used to identify iron powder and graphite powderHurry up, you need it urgently! Thank you

First, with a magnet, you can use a magnet, can be sucked into the iron powder.Two, put in the water, floating above the sink in the bottom of the graphite powder, iron powder

Q:Why can graphite powder conduct electricity?

Dense crystalline graphite is also called massive graphite. These crystals are crystalline and visible to the naked eye. Particle diameter greater than 0.1 mm. The crystals are arranged in a dense and blocky structure. The graphite is characterized by a very high grade, general carbon content is 60 ~ 65%, sometimes up to 80 ~ 98%, but its plasticity and unctuousness as fine flake graphite.

Q:Can ultrafine powder iron conduct heat? How many purpose graphite powder can be called superfine stone powder? Pingdu graphite powder which good?

In general, the average particle size of graphite powder is less than 10 m, you can call ultrafine powder toner, in fact, more than the use of ultrafine particles of toner, you can see Qingdao Huatai graphite, I hope to help you.

Q:The principle of a graphite missile

The graphite missile contains carbon fibers and is highly conductive. After the explosion of carbon fiber floats attached to the high-voltage lines immediately cause transformer short circuit burned, to destroy the enemy's power to.

Q:How does graphite powder solidify into a lump? What bond is best used?After solidification can be more than 1000 degrees high temperature does not change

The only way to do this is by using physical methods, high temperature and high pressure, to agglomerate the graphite powder from the molecular level. Now, by simulating the high temperature and pressure of the earth's crust, graphite can be turned into diamond (that is, diamonds)

Q:Graphite powder screening process, because with static holding together, resulting in vibration screen plugging network how to solve?

Electrostatic earthing or electrostatic eliminator. In fact, there is a certain conductive graphite powder is very fine, but so long as the electrostatic would slightly have great effect, give you two ways, one is the good grounding conductor can be static vibration sieve, go through a grounding wire guide;

Q:How much is one graphite used as electrode?

Product Name: graphite electrode, graphite crucible, graphite plate, graphite tile, graphite powderProduct price: 7000 yuan / tonCompany location: Hebei, Handan
