The utility model relates to a graphite electrolytic cell, which relates to an electrolytic cell used for smelting rare earth metals. The main is to solve the problems of rare earth metal graphite electrolytic bath existing contact air directly on the inside of the upper part of rare earth metal smelting, under the condition of high temperature oxidation burning problem of. The invention is mainly in the rare earth metal graphite electrolytic bath with high temperature resistant upper inside protection metal cover, protective cover on the outward along the graphite cell volume will cover the upper, high metal protective cover is approximately equal to the depth of 1/3 graphite cell. The advantages of upper inside of the graphite electrolytic tank…
Graphite carbon plate adopts high quality graphite carbon material, and the organic compound with strong acid resistance is added. By high pressure molding, vacuum impregnation, high temperature heat treatment The process is refined, has the special acid resistance and the temperature resistance performance, is the chemical industry phosphoric acid reaction trough, the phosphoric acid storage tank and so on equipment ideal lining material. Excellent corrosion resistance Products using carbon graphite material quality, adding organic compound with strong acid, effectively reducing the product porosity increases, the bulk density of the products, so the product has strong corrosion resistance and excellent wear resistance. Stable performance, strong durability The product is made of high strength organic glue as binder, and the high and…
High purity graphite: graphite content of more than 99.9% of graphite called high pure graphite. Is an ideal inorganic non metal crucible boat, crystal furnace heater, EDM graphite, sintering mold, tube anode, metal coating, semiconductor technology with graphite crucible, electron tube, thyratron and mercury arc rectifier with graphite anode, grid etc.. High purity graphite has the advantages of small resistance coefficient, high temperature resistance, corrosion resistance, oxidation resistance, good thermal shock resistance, electrical conductivity, thermal conductivity, small coefficient of expansion, self lubrication, easy machining precision and so on. 1) high temperature resistant graphite melting point of 3850 - 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is…
