method and device for the production of spherical particles from liquid phase.

摘要

For the preparation of spherical particles having a narrow particle size spectrum by producing drops by means of a nozzle from a liquid phase having melting points of up to 1500 DEG C, the liquid phase, the nozzle and the falling distance of the drops until stabilisation of the spherical shape of the falling drops are kept at a constant temperature which is 1 to 10 DEG C above the melting point of the liquid phase. The particles must then be abruptly quenched.
