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:What are the technical specifications of graphite crucibles?
Crucible; physical and chemical index; standard parameter; test dataThe refractoriness is 1680 degrees, and the refractoriness is 1685Carbon content 38%, carbon content 41.46%Porosity less than 35% porosity is less than 32%Volume density 1.6g/cm3 volume density 1.71g/cm3The above data are referred to Qingdao Huatai graphite, hope to adopt, thank you.
Q:Graphite producer / graphite manufacturer / graphite enterprise brand, where is there?
There are a lot of production of graphite materials manufacturers, such as Henan Pingdingshan Kaiyuan, Wuxing, exhausted Shi ah, abroad with the East China Sea, Japan, Roland, SGL etc.
Q:Does the graphite metal pad have any requirements on the sealing surface?
Metal wound gasket:Metal wound gasket is a sealing gasket is used widely at present, in order to return to the best elastic gasket semi metallic gasket, by V or W shaped steel strips with various fillers alternately wound together, high temperature, high pressure and adapt to the use of ultra low temperature or under vacuum conditions, by changing the gasket combination of materials, can solve the problem of all kinds of chemical corrosion medium on the gasket, the structure density can according to different requirements to lock force production, in order to strengthen the body and accurate positioning, the gasket ring and the outer ring is provided with positioning reinforced metal, using internal and external steel ring to control the maximum compaction degree, the sealing surface precision requirement is not high the surface of the flange gasket contact.
Q:How to reduce the degree of oxidation of graphite when sintering at high temperature?
(1) reasonable furnace geometry and feeding order;
Q:The difference between single graphite furnace graphite furnace atomic absorption spectrophotometer and double graphite furnace
The flame burner operation condition selection (TS lifting capacity, flame type, burner height)Selection of optimum operating conditions for graphite furnace (optimum atomization temperature of inert gas)
Q:Why graphite and diamond is composed of carbon graphite, but not light, is black, and the diamond is urgently in light!
Although they are all carbon, the arrangement of the carbon atoms is different, so different structures lead to different physical properties
Q:What are the two methods of atomization? What orders of magnitude can be measured?
The sharp line spectrum of the A light source as the light source for analyte emission of sufficient strength, tellurium, atomic system. Quartz furnace atomic system is the gaseous analytes a method of introducing quartz furnace atomic intrinsic low temperature: electrodeless discharge lamp B atomizer without hollow cathode lamp (atomizer) can be divided into pre mixed flame atomizer (premixed flame atomizer), small, amplifier, ashing and background stability generally used; the level of mL, 10-9g/ were detected by flame atomic absorption spectrometry. The hydride generator can be used for 8 kinds of volatile element mercury. The atomic absorption spectrometer consists of an atomic absorption spectrometer that consists of a light source: an atomizer
Q:How do you use crucibles to process copper?
The medium frequency furnace crucible is made of quartz sand lining material, and the crucible has a long service life, usually in three months. The power frequency furnace is also sintered with quartz sand.
Q:Application of ceramic fiber module in gas crucible furnace
The ceramic fiber module plays a major role in fireproof and heat preservation in the gas clamp boiler, and prolongs the service life of the Tong boiler. According to the different materials of the gas tongs boiler, the refractory and heat preservation materials used are different, and the ceramic fiber module, refractory fiber board and refractory pouring material are all the heat preservation materials used by the conventional clamp boilers.
Q:You solved it. What happens if a quartz crucible is coated with a graphite crucible?
The graphite crucible will burn on an alcohol burner, and the quartz crucible may cause cracks due to uneven heat.
