передовые производства монокристаллического кремния

float zone single crystal silicon Our advantages on owner's power supply make the cost lower, so Xinhua have cost value advantage.welcome to contact us for product. the FZ growers principles: The growth proess starts by inserting a polycrystalline ingot into the upper chamber/pulling arrangment.Thereafter the ingot is pre-heated by means of a graphite heater.After pre-heating,the graphite heater is swung away and the cone_shaped ingot is lowered into the active zone of the high frequency coil.which is now able to melt the silicon ingot to the seed crystal.The one-pass monocrystalline growth process can now begin.
