Crystal Growth Furnace with Tungsten Crucible

Sapphire crystal growth furnace thermal field and supporting tungsten and

molybdenum crucible with a high density, high purity, high precision machining.

tungsten crucible

Tungsten crucible is one of tungsten products, mainly divided into sintered molding, stamping, spinning type, the use of molybdenum rod turning forming, welding molding variety, using pure tungsten plate, tungsten plate and pure tungsten rod through the appropriate processing technology from. 2600 degrees in a vacuum with an inert gas.

The melting point of tungsten, high boiling point, high strength, anti-friction, corrosion resistance, thermal conductivity, thermal expansion coefficient, good hardenability, widely used in rare earth smelting, quartz glass, electronic coating, sapphire crystal growth and other industries.

Sapphire crystal growth as the main carrier, tungsten crucible temperature, low thermal expansion coefficient of the sapphire growth to meet the conditions at high temperatures, the tungsten material of the crucible is not easy to react with the alumina, sapphire ensure purity.

Crystal Growth Furnace with Molybdenum Products Characteristics

Molybdenum in the crust abundances approximately 1 × 10-6, in igneous rocks like

molybdenum crucible

granite molybdenum highest, at 2 × 10-6. Molybdenum in geochemical classification, a transitional pro- iron . Including the role of generating ore , molybdenum and sulfur combine mainly produce molybdenite .

Silver-white metal , hard and tough . Density 10.2 g / cm 3. Melting point 2610 ℃. Boiling point 5560 ℃. Valence of +2, +4 and +6 +6 stable price . Molybdenum is a transition element , easily changes its oxidation state .

Redox reactions in the body plays a role in electron transfer . The oxidized form, the molybdenum is likely to be in the +6 state. Although the electron transfer during which it is also likely to be restored first +5 valence state, but after the restoration of the enzyme has been found in other molybdenum oxidation state . Molybdenum is a xanthine oxidase / dehydrogenase, aldehyde oxidase and sulfite oxidase components , thereby acknowledge their animals for the human body and essential trace elements . Various human tissues are molybdenum , adult body total 9mg, liver and kidney of the highest concentrations .

Pure molybdenum wire for high temperature furnace and wire cutting EDM there ; molybdenum sheet used to manufacture radio equipment and X-ray equipment ; adding molybdenum alloy steel can improve the elastic limit , corrosion resistance and to maintain permanent magnetism . Molybdenum is required for plant growth and development in the seven kinds of micro-nutrients in one, without it, the plants can not survive. Animals and fish, and plants that also need to molybdenum .

Because molybdenum high temperature , heat and other characteristics, such as in the emerging Sapphire Dan Changjing processing industry has been widely used .

In addition , the combination of molybdenum and silicon , is a good heating element.

LED Sapphire Substrate Domestic Overcapacity Crystal Growth Furnace Caught "Survival Technique"

" One side is GT, ARC and other foreign manufacturers of extrusion, the other side is the sapphire substrate excess capacity, demand, prices have been falling , domestic manufacturers of crystal growth furnace is now survive in the cracks , and development ." Domestic Sapphire furnace Dan Changjing a company official told the " Engineering LED" reporter .

"As of now , the company's Sapphire Dan Changjing furnaces sold dozens ." This is the Dragon Optical (SZ.300029) interactive platform for investor relations in the Shenzhen Stock Exchange on the answer given .

Sapphire Dan Changjing furnaces

According to Engineering LED Industry Institute (GLII) recently released report, 2012 China mainland chip output of about 7.2 billion yuan , the average price fell about 32% , a decline of some products is as high as 50% .

GLII data show that in 2012 China mainland holdings from 2011 's 803 units to 917 units, but the capacity utilization rate is only about 30%, the boot was only about 50%.

Low capacity utilization led directly upstream sapphire substrate and Sapphire Dan Changjing furnace corporate sales slump last year , the price all the way down . Currently , two-inch sapphire substrate market price has reached a cost of $ 7-8 near the line , more manufacturers in Taiwan and South Korea call for $ 6 of the "cheap ."
