A Method for Producing a Freeze-Cast Substrate

摘要

A freeze-cast substrate is produced by introducing a slurry (30) in a mold unit (10) comprising a mold (12) contained within a substrate receptacle (14) and lowering the temperature of the slurry to freeze the slurry and form a freeze-cast substrate while controlling temperature gradients in the mold unit to minimize distortion in the freeze-cast substrate (34). An independent claim is also included for a mold unit for producing a freeze-cast substrate from a slurry, comprising: a mold; a substrate receptacle having four interconnected side panels having an inner surface and outside surface; and a layer of insulating material.
