Title:
HOLLOW CERAMIC FIBER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH06294019
Kind Code:
A
Abstract:

PURPOSE: To produce a hollow ceramic fiber composed mainly of Si, N and 0 and usable as a material for filter, adsorbent, heat-insulation material, various composite materials, etc.

CONSTITUTION: A solid ceramic fiber containing Si and N as essential components is heat-treated in the powder of an oxide-based ceramic in vacuum or in an inert gas atmosphere to obtain the objective hollow ceramic fiber. The solid ceramic fiber is preferably produced by baking a ceramic fiber precursor made of a polysilazane.
