2119894 9305904 PCTABS00021 A method for preparing glass-coated microwires is provided. A metal (12) in a glass tube (11) is superheated in a high frequency induction field (13), whereby the glass and the glass tube fills with molten metal. The metal-filled capillary enters a cooling zone (16) in the superheated state and the rate of cooling is controlled such that a microcrystalline or amorphous metal microstructure is obtained. The cooling zone (16) includes a stream of cooling liquid (17) through which the capillary passes. The microstructure of the microwire is controlled by choice of amorphisizers, cooling rate, nature of the cooling liquid, location of the cooling stream, dwell time in the cooling stream and degree of superheating and supercooling of the metal.
