The graphite products are divided into two major categories of flake graphite and microcrystalline ink: flake graphite refers to the natural crystal graphite, the shape of covered, by crystal, flaky graphite ore processed, ore dressing, sometimes by purification products;Microcrystalline graphite has called earthy graphite or amorphous graphite, refers to the tiny natural graphite crystals composed of dense aggregate, by implicit crystal, earthy graphite ore processed, some after the separation, purification products. Flake graphite according to fixed carbon content is divided into high purity graphite, graphite in high carbon graphite, carbon and low carbon graphite four types, according to the product particle size, fixed carbon content is divided into 212 kinds of brands, various grades of graphite products technical requirements are…
Using graphite as electronic conductor material of the electrode.Graphite chemical properties is stable, low overpotential of chlorine, good mechanical strength, easy processing, price moderate.Is widely used in industry, such as used in dry cells positive electrode collector body (graphite rod), industrial electrolytic cell anode, etc.Of chlor-alkali industry in the early, chloride with graphite electrode material, but the drop of slag after chlorine corrosion such as chip jams diaphragm is easy to cause short circuit, shorten the life of electrolyzer, is gradually replaced by titanium form stable anode.In the lab is also commonly used as a price lower inert electrodes. The graphite used discharge loss smaller;Because the spark oil also contains C atoms, in electro discharge machining, the C atoms are…
Czochralski silicon single crystal thermal field in the pulling of monocrystalline silicon and polysilicon ingot furnace with heater in thermal field, isostatic pressing graphite parts have crucible crucible, heater, electrode, insulation shield, seed crystal holder, rotating with the base of the crucible, all kinds of round board, thermal baffle, about 30 kinds. Among them, 80% of the isostatic pressing graphite used in the manufacture of crucible and heater, etc. In recent years, the diameter of the requirements of single crystal silicon rod is more and more big, 300 mm wafer production has increasingly become the mainstream. Accordingly, the single crystal furnace heating zone, most of the 800 mm diameter, the graphite crucible furnace in order to protect the place of…
