Introduction 

1. Graphite crucible can be used for non-ferrous metal smelting and casting, 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 jewelryindustry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles accordingto 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 wil 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.


4. widely used in such fields as industrial furnaces, mono-crystalline silicon machinery, mono-crystalline silicon machinery, electron, semi-conductor, metallurgy, oil, chemistry, textile, electrical machinery, electrical equipment, electrical furnace, traffic, communication industry, medicine, etc.

Q:Help: how can the graphite crucible be heated to 1000 degrees?
No matter what heat is used, heat it to 1000 degrees. Just keep heating it. Graphite crucible can be used to contact outer ring refractory plant
Q:What is the conductivity of graphite and the conductivity of graphite?
The conductivity and thermal conductivity are different for different grades of materials.
Q:The graphite boat loading and loading real real graphite boat is what?
Efficient air through the filter, the damping level pressure, the clean air flow into the vertical unidirectional loading area, so as to ensure the work in the region to achieve the technical requirements of the cleanliness of the operator in a clean environment to the graphite boat on silicon wafer.
Q:Is the heat conductivity of the crucible good for graphite or iron?
The thermal conductivity of special graphite is 83~150,The thermal conductivity of iron is 80,The thermal conductivity of cast iron is 43,
Q:Why does China choose quartz crucible directly in the aspect of Czochralski silicon?
Because (1) the melting point of silicon is at 1450 degrees, the container for molten silica must be sufficiently high. (2) Czochralski silicon is the rearrangement of the atomic structure. High purity is essential and insoluble impurities. Quartz crucible material is SiO2, high temperature and stability, will not bring other impurities. That is, the O atoms of the quartz crucible also affect the quality of monocrystalline silicon. (3) when foreign countries engage in these scientific studies, China is still living long with the emperor, so these technologies were introduced into China in the last century of 50s, and the current development is still 50 years from home!
Q:What is the importance of carbon graphite as biological material?
What is the importance of carbon graphite as biological material?Because graphite has many excellent properties, it has been widely used in metallurgy, mechanical, electrical, chemical, textile, national defense and other industrial sectors.
Q:Does the smelting of nonferrous metals, graphite crucible and cast iron crucible which is easy to use?
The pollution of carbon to aluminum alloy and copper alloy should be less than that of iron to aluminium alloy and copper alloy, but the iron crucible is durable and easy to use
Q:What is graphite?
Graphite is a carbon crystal, is a non-metallic materials, color silver gray, soft, with a metallic luster. Mohs hardness is 1~2, specific gravity 2.2~2.3, and its bulk density is generally 1.5~1.8.The high melting point of graphite, trend began to soften under vacuum to 3000 DEG C when the melting state, up to 3600 degrees Celsius began when the evaporation of graphite sublimation, the general strength of materials under high temperature gradually decreased, while the graphite in the heating to 2000 DEG C, rather than the room temperature strength is doubled, but the oxidation resistance of graphite poor performance with temperature increased oxidation rate increased.Graphite has a fairly high thermal conductivity and conductivity, its conductivity is 4 times higher than stainless steel, 2 times higher than carbon steel, 100 times higher than ordinary non-metallic. Its thermal conductivity is not only more than steel, iron, lead and other metal materials, and with the rise in temperature, thermal conductivity decreases, which is different from the general metal materials, at very high temperatures, graphite and even tend to adiabatic state. Therefore, the heat insulation properties of graphite are very reliable under ultra high temperature.
Q:Graphite and diamond are elemental elements made of carbon. Why are physical properties so different?
Purpose: GraphiteIn the metallurgical industry, used in the manufacture of graphite crucible and foundry mold surface coating and furnace lining and protective slag;Electrical industry, do electrodes, brushes, batteries, positive conductive materials, carbon tubes and so on;In the chemical industry, it is used as catalyst material for acid and alkali products and chemical fertilizer industry, as well as high temperature resistant and high pressure seals;In addition, it can also be used as lubricant, anticorrosive paint, pigment, pencil core, gunpowder, neutron reduction agent in atomic reactor and anti corrosion agent in aerospace industry
Q:Cast iron into a casting. What is the state of the matter, change, sublimation?
Cast iron into a casting. What is the state of the matter, sublimation?Container for molten iron called graphite crucible, good high-temperature resistance, it is higher than the melting point of iron.
