NOVELTY - All that accumulated and collided powders are connected directly or indirectly on board. Plate-shaped coupling component which consists only of raw material metal extra fine amorphous grain, amorphous grain which raw material metal extra fine solution drop solidified, or plate-shaped coupling component of extra fine crystal grain which raw material metal extra fine solution drop solidifies and produces film. Pure amorphous of raw material metal, or amorphous portion and crystallization portion of raw material metal becomes semi-amorphous mixed, to obtain amorphous board.    USE - Manufacture of amorphous board e.g. pure amorphous alloy thin plate used for electric power apparatus, fuel cell, chemical processing plant and measurement apparatus.    ADVANTAGE - The amorphous board has excellent corrosion resistance and electromagnetic characteristic, secondary fabrication property and durability.    DETAILED DESCRIPTION - Raw material metal powder containing metal powder and/or alloy powder, is conveyed through a required path using carrier gas, and simultaneously mixed with required combustion gas. The raw material metal powder is heated and dissolved using combustion heatgeneration of combustion gas, and simultaneously, enters into nozzle which has required shape and dimension pass. While mixing the dissolved raw material metal powder, with combustion gas and carrier gas in combustion, it is made to eject in inert gas atmosphere. A jet stream of extra fine solution drop in which the diameter of raw material metal is 2-100 mu m is invented. While maintaining the jet stream of raw material metal extra fine solution drop, it merges diagonally crossing with the jet stream from circumference of raw material metal extra fine solution drop jet stream. A required refrigerant jet stream is blown in each droplet in the raw material metal extra fine solution drop jet stream is rapidly cooled. The injection pressure, spray velocity, amount of ejection, ejecting direction and crossing angle with the raw material metal extra fine solution drop jet stream of refrigerant jet stream are set appropriately. It is made to merge such that requisite quantity of refrigerant jet stream can attain stably center portion of raw material metal extra fine solution drop jet stream. Each droplet in raw material metal extra fine solution drop jet stream is rapidly cooled in general with the cooling rate of 1 million degrees-C/second or more. All raw material metal extra fine solution drops are made amorphous, or required one portion is made amorphous. All raw material metal fine solution drop jet streams or its one portion is converted to raw material metal fine amorphous grain jet stream during flow, the raw material metal fine amorphous grain jet stream or mixing jet stream of raw material metal fine amorphous grain jet stream and raw material metal extra fine solution drop jet stream is invented on a required heated board, it sprays by means of required temperature and rate. While colliding and depositing the mixture of raw material metal extra fine amorphous grain contained in inside or raw material metal extra fine amorphous grain, and raw material metal extra fine solution drop on board, the kinetic energy released by heat energy and collision which they which are deposited is exploited. All that accumulated and collided are connected directly or indirectly on board. The plate-shaped coupling component which consists only of raw material metal extra fine amorphous grain, amorphous grain which raw material metal extra fine solution drop solidified, or plate-shaped coupling component of extra fine crystal grain which the raw material metal extra fine solution drop solidifies and produces film. The pure amorphous of raw material metal, or amorphous portion and crystallization portion of the raw material metal becomes semi-amorphous mixed in a target ratio, to obtain amorphous board. An INDEPENDENT CLAIM is included for amorphous board.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining manufacture of amorphous board.
