Q:25%, the fracture of graphite rod, pressing problem or sintering problem?

25% of the filling, 40 feel a little lower, and personally recommend using 50MPa. How long have you been under pressure? Suggest 20-30 minutes. Release the pressure a little slower, it will crack soon. Sintering, the insulation point does not need so much, 340, 320, recommended insulation for 4 hours. Also suggest that you do not put too many blanks in a furnace, it is better to cover in the middle, rough heating and heat dissipation will have an impact.

Q:Not that the solid does not conduct electricity, like the solid potassium chloride, but why the graphite rods, wires, these solids can conduct electricity

Since there is no moving charge in potassium chloride crystals, it naturally cannot conduct electricity. Potassium chloride in molten water and in molten state, because of the free movement of chloride and potassium ions, it can conduct electricity

Q:What kind of sketch do you want, Shi Mobang?

No, it's about two or three yuan for a box and ten for two months. Graphite can be used instead.

Q:How good is the conductivity of graphite and the conductivity of copper?

In theory, copper, depending on the resistivity of the materialThe lower the resistivity, the better the conductivityThe following is the resistivity of some objects.

Q:How many times will a high pure graphite stick turn red at temperature?

With the increase of temperature, the oxidation rate is increased, if the nitrogen protection, can reduce the oxidation rate, so some high temperature furnace, vacuum furnace and vacuum extraction is to prevent the oxygen in the air oxidation of graphite, McNair to answer your questions.

Q:Why is there no graphite rod in battery five now?!

Because of the size of battery 5, but not with graphite rods, what specific use, and then wait for an expert

Q:What is the difference between the conductive effects of different grades of graphite? Refers to the pencil core

2B first draft, and then use the 2H~8B tone. HB is the pencil hardness of B H--HARD concentration, B--BLACK density number is more soft black pencil, H number is more hard color the more light was.HB. The main component of the pencil core is graphite. In fact, the pencil lead is by graphite and clay made by blending.

Q:Copper, graphite rods, dilute sulfuric acid, why not make up the original battery?

The base of a galvanic cell must have a spontaneous redox reaction to convert chemical energy into electrical energy.

Q:What is Teflon graphite stick for?

Should be called graphite modified (reinforced, filled) PTFE bar, rod profiles are used for processing fine size parts. The material is made from polytetrafluoroethylene and reinforced with graphite reinforcing agent (or carbon fiber).

Q:Is graphite rod resistant to sulfur corrosion?

The corrosion resistance of graphite with good thermal conductivity, low permeability, can be used for the production of heat exchanger, reactor, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment.
