Q:Is the graphite powder produced with sulphuric acid?: Graphite powder can smash through physical production method, also can be produced by sulfuric acid and other chemical methods, according to different types of graphite powder, the production process is not the same, I hope there is help for you, hope to adopt, thank you.

Q:Is oxygen allowed in the oxygen pipe?: To tell the truth, the graphite powder also belongs to small particles, if the medical oxygen pipe can not have graphite, if industrial oxygen, can have the physical and chemical properties of graphite, graphite and other stable, will not react, to a certain extent is a kind of preservatives, prevent oxidation function.

Q:What is the use of flake graphite in making flake graphite powder?: Flake graphite powder: natural crystalline graphite, the shape of fish like phosphorus, is a six party crystal system, layered structure, with good resistance to high temperature, conductive, heat conduction, lubrication, plasticity and acid and alkali resistance.

Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.: Any object that is crushed will have a surface energy (internal energy), but the temperature will not increase, so the specific heat will become largerFuel burns because its energy is already full (reaching a point of fire)When the object reaches the ignition point, internal energy = (ignition +273.15) * specific heat capacity

Q:It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?: Suggestion: use a certain amount of concentrated nitric acid infiltrated graphite part, nitrate solution the best there is a certain amount of 1-2 weeks (timing can also be placed with a glass rod, pour stirred) acid, diluted with water to acid and then scrub brush. Because the temperature nitric acid reaction is very slow, but the long-term infiltration, the graphite surface. Especially with the glass contact surfaces may be immersed in a small amount of acid, oxidation, then scrub may have the effect.

Q:Can ultrafine powder iron conduct heat? How many purpose graphite powder can be called superfine stone powder? Pingdu graphite powder which good?: Ultrafine toner is a thermal conductive function, because ultrafine toner is processed from natural graphite, which inherits the characteristics of natural graphite conduction and heat conduction.

Q:What is graphite powder?: Graphite is soft, black and gray; greasy feeling, can piece of paper pollution. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. Under normal temperature and chemical properties of graphite is relatively stable, insoluble in water, dilute acid and dilute alkali and organic solvent; different high temperature reaction with oxygen, carbon dioxide or carbon monoxide; only in halogen fluorine can react directly with elemental carbon; under heating, the graphite powder is easy to be oxidized under high temperature, acid; but with many metal reaction, formation of metal carbides, can smelt metal at high temperature.

Q:Graphite powder made of graphite oxide, how much weight gain?: The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5.

Q:What is special graphite powder used in graphene?: In terms of hardness, diamond is of great hardnessI see your supplementThat part of the encyclopedia is wrongThe advantage of graphene is that its hardness is great compared to other materialsBut you can't compare with diamond

Q:Method for identifying iron powder, aluminium powder and graphite powder: They can be used to determine the reaction with acid: the same quality, the same mass fraction of dilute hydrochloric acid solution, and then the three kinds of powder into three kinds of solution, graphite powder and hydrochloric acid reaction observed, iron and aluminum powder and hydrochloric acid hydrochloric acid reaction is slow, can react violently, prove that the nature of the most active aluminum iron, the main component of carbon graphite is the most stable chemical properties.
