Product Description


Specifications for Graphite Silicon Carbide Crucible For Aluminum Melting :

1.Long working lifetime: its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure.

2.High thermal conductivity: high-density body and low apparent porosity greatly improve its heat conductivity.

3.New-style materials: new heat conduction material ensures faster heat conductivity and pollution-free product, reduces adherent slag.

4.Resistance to corrosion:better anti-corrosion than normal clay-crucible.

Q:Help: how can the graphite crucible be heated to 1000 degrees?
1000 degrees, the use of electricity, coal, gas can be enough to achieve.
Q:The graphite boat loading and loading real real graphite boat is what?
Main features:1, can make accurate Shi Mozhou bearing loading vehicle positioning;2 、 made of stainless steel, the structure of the whole machine is firm and reliable;3 、 adopt GK series high efficiency air filter 3;4, PECVD carrier car inside, can tilt 15 degrees or rotate 180 degrees;5 、 purification fan noise is less than 50dB.6, to ensure that the work area to achieve the requirements of cleanliness 100.
Q:What are the differences in production techniques for different graphite crucible models?
. Pliers can be divided into three categories: metal tongs, clay crucibles and graphite crucibles. Lynn disaster can be divided into: graphite crucible, crucible smelting and refining non-ferrous metal alloy steel can curse three. According to the shape is divided into universal and special-shaped two.
Q:Why does China choose quartz crucible directly in the aspect of Czochralski silicon?
Hello, quartz crucibles are the necessary accessories for CZ crystals. They have not been heard to replace quartz crucibles. You are new enough.
Q:Electromagnetic induction heating device into the copper coil heater, to use more power consumption to reach the melting temperature of iron?
The roommate's induction heater comes from a copper tube with water through it
Q:What are the two methods of atomization? What orders of magnitude can be measured?
It is mainly used in conjunction with the vapor generation process (hydride generation, high temperature purification, high atomization efficiency). C optical system (monochromator) by the concave mirror, graphite furnace atomizer (graphite furnace atomizer), cathodic sputtering atomizer (cathode sputtering atomizer): in the high temperature adjustable sample utilization rate of 100% high sensitivity. A flame atomization, tin. The atomization program is divided into drying, resolving power and collecting power, and the D detection system consists of detector (photomultiplier tube). D. The tube type graphite furnace atomizer is the most commonly used: simple operation, optical system and detection system, atomization is one kind will be placed in the tube wall and the graphite platform; the magnitude of mL, the performance of selenium: the detection limit of 10-6~10-14 samples of low dosage, slit or dispersion components dispersion element as a prism or diffraction grating monochromator is the dispersion rate and good reproducibility of B graphite furnace atomizer, also called low temperature atomization method, mercury vapor generation and volatile compounds), will be measured directly from the solid surface elements into atomic vapor and germanium micro determination of trace carbon or graphite, sample hole the crucible system atomization with electric heating to a high temperature can be measured by 10-13g/ graphite furnace atomic absorption spectrometry.
Q:How can food detect heavy metals and microbes?
Single sweep polarography, it is a kind of controlled potential polarography, the electrode potential is a linear function of time, by observing current oscilloscope. Potential curves, it is also called the linear displacement oscillopolarographic method, the detection limit was 0.085mg/kg.Two sulfur colorimetric method, the method used two sulfur hydrazone as chromogenic agent, by comparing or measuring the color depth of the solution to determine the content of the component under test, the detection limit is 0.25mg/kg.
Q:Aluminum graphite crucible for iron crucible which is good
Our factory is specializing in the production of graphite crucible, if you are engaged in the die casting industry, the best use of graphite crucible for die casting, requirements of iron content, iron, aluminum and iron will seep into the water, so it is best to use a graphite crucible.
Q:What are the catalysts for making SiC from rice husk?
A method for manufacturing silicon carbide using carbonized rice husk as the main ingredients: Carbonized rice husk and coke silica into sodium hydroxide and water by hydrothermal method, in 200 - 300 DEG C to 24 + 5 hours temperature, pressure and 50 - 1500 ATM, synthesis of silicon carbide. The present invention has low reaction temperature and low cost, and is suitable for mass production in industry.
Q:How to extract gold from activated carbon filter?
High temperature roasting filter core with graphite crucible and acetylene burner.
