Filter medium for metal hot melt and treatment process for metal hot melt.

摘要

Disclosed here are a filter medium for a metal hot melt which is obtained by precipitating needle-shaped crystals on the surfaces of ceramic fillers; and a treatment process of the metal hot melt which comprises the steps of using the ceramic fillers on the surfaces of which needle-shaped crystals are precipitated, and bringing the metal hot melt into contact with the ceramic fillers. The employment of the filter medium can lead to the improvement of a filter performance of the ceramic fillers.
