Patent ID: 8343276

Claim:
A compound crystallization system, comprising: a radio frequency magnetic field high-temperature ion diffusion unit, having an ion diffusion chamber, which comprises a first quartz vacuum prefabricated tube, a second quartz vacuum prefabricated tube, a group of external high-frequency field coils encircling a peripheral surface of said first quartz vacuum prefabricated tube, a quartz heater provided outside said first quartz vacuum prefabricated tube, and two flange valves provided at a top of said first and second quartz vacuum prefabricated tubes respectively; a compound fluidized bed comprising: two high-temperature quartz reaction furnaces provided within said high-temperature ion diffusion unit; an arched quartz heating tube communicating with a top of said two high-temperature quartz reaction furnaces; two silicon electrode heating bodies provided within said two reaction furnaces respectively; and two cylindrical stainless steel fixed flanges sealedly provided at a bottom of said two reaction furnaces, respectively, wherein each of said fixed flanges has an air inlet, an air outlet and a high-speed current wave impact hole for Ar, H 2 separately located at a peripheral inner of said fixed flange respectively; an active stainless steel center flange comprising 4-6 pairs of electrodes, a high-temperature ceramic sealed cartridge, a water-cooled sealed room and sealed hydraulic elevator; and a vacuum material room provided below said cylindrical stainless steel fixed flange, wherein said active stainless steel center flange is provided within said vacuum material room, whereby reaction gas is effected by a group of high-frequency external magnetic fields and forms the high-temperature gaseous ion in said first quartz vacuum tube, then forms ion deposition diffusion in said second quartz vacuum tube preheated at constant temperature, in such a manner that other high-temperature gaseous ions except the silicon hydride are decomposed, rapidly deposited and crystallized in said ion diffusion chamber, and the un-decomposed silicon hydride gas is directly poured into a surface of said silicon heating body of said compound fluidized bed to decompose and crystallize, or crystallize by a way of fluid state in said arched heating quartz tube communicating with the top of said two quartz reaction furnaces.
