ABSTRACT:
The plate-like structure is formed of glass filaments and a solid ceramic skin which envelopes the glass filaments to form a skeleton-like supporting structure. The glass filaments are also fused to each other at intersecting points to impart stability to the structure.
The method of making the structure includes the steps of forming a coating of a ceramic substance which is capable of being fired on a flat structure of glass filaments. Subsequently, the coated structure is fired at a temperature in a range from 600.degree. C. to 1500.degree. C. to form a solid skin of the ceramic substance while causing the glass filaments to fuse together at the intersecting points of contact.
Packings for material and heat exchange processes can be made from the plate-like structures.
