Advantage: 1. High density 2. Good thermal stability and distortion resistance at high temperature. 3. High mechanical strength at high temperature.
4. Excellent thermal shock resistance. 5. High thermal conductivity. 6. Perfect oxidation resistance. 7. Excellent corrosion resistance against chemicals at high temperature. 8. High abrasion resistance.
9. Long service life.
Applications 1. Graphite crucible can be used for non-ferrous metal smelting and casting, melting aluminum, dissolving gold or silver ornaments, analysis of special type steel, sintering hard metal. 2. Graphite crucible for smelting gold is specialized in melting gold in headgear and jewelry industry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles according to customer's requirement. 3. Machined from high pure graphite and widely used in the gold,silver,platinum and other noble metal's melting.If it's used in oxygen atmosphere,it will start to be oxygenized when the temperature is higher than 700-800°c. If it's used in the protective atmosphere, it can stand more than 2000°c.
Notes of usage for graphite crucible: 1. The crucible should be stocked in the dry situation. 2. Carry the crucible carefully 3. Warm the crucible in the drying machine or near the furnace. The warming temperature should be up to 500℃. 4. The crucible should be put under the furnace mouth flat. 5. When put the metal into the crucible, you should take the crucible capacity as your reference. If the crucible is too full, it will be damaged by expansion. 6. The clamps shape need as that of crucible. Avoid the concentrate stressed destroy of the crucible. 7. Clean the crucible regularly and gently. 8. The crucible should be put in the center of the furnace and leave some distance between the crucible and furnace. 9. Turn the crucible once a week and this will help prolong the service life. 10. The flame should not touch the crucible directly.
