3M has had a silicon carbide, SiC, matrix/oxide fiber, ceramic composite, candle filter in test and on the market for several years. Because of the effects of some corrosive environments, 3M is developing an oxide matrix/oxide fiber hot gas candle filter which will be better suited for some of the environments which can degrade SiC. This paper will discuss the progress of the development of the oxide/oxide candle filter. Composite panels using three different Nextel{trademark} fibers but the same matrix material have been exposed to different simulated environmental conditions in the laboratory. Data will be presented on the effects of these environments on the composite panels. Also prototype candles have been made from the oxide/oxide system and data will be presented on the filtration characteristics, construction, and laboratory environmental exposures of these filters. Finally, if available, data will be presented on 12-in candle filters which have been exposed in an industrial test facility.
