Studies of Ceramic Processing.
Abstract
The overall objectives were to improve structure and engineering properties, and to lower the firing temperature yet retain all engineering properties including refractoriness. Magnesium spinel was selected for study in the highest temperature range and cordierite for the lowest. Reactive spinel was prepared from pure alums by prereacting at 1150C. Four variables were studied namely composition, firing temperature, firing atmosphere and soak time. Structure studies were included and proposed sintering mechanisms for this compound are presented. In the lowest temperature range cordierite was selected. A single glass system was devised in which the desired cordierite content and content of the desired bonding glass could be fritted into one glass. During sintering of specimens prepared of the communited frit, cordierite was devitrified and the body matured. Sintering behavior versus a number of properties was studied along with structure and the devitrification behavior of the cordierite phase. The anticipated structure improvement was realized and the fact established that the composition of the bonding glass is critical. (Author)
