National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Publication Date	1974
Personal Author	Wachtman, J. B.

Abstract	The degradative processes which ceramics in high temperature gases produced by coal conversion may undergo are briefly reviewed. These include purely chemical processes such as combination of liquids in cracks and subsequent corrosion. These also include chemical modification of physical processes of deterioration such as environmental effects in fracture.
