Silicate Compositions Database

Degradation of thermal and environmental barrier coatings (T/EBC) by
interactions with molten silicate deposits (ash, sand, dust) poses a
fundamental threat to progress in gas turbine technology. This file is the
first publicly available, comprehensive database of its kind on potential
silicate deposits. It features in an accompanying article addressing an
original ICME-inspired approach (Integrated Computational Materials
Engineering) to analyzing the high dimensional data. The article
responds to a longstanding need for identifying a reasonable number of
silicate compositions that may represent the wide variability in engine
deposits arising from the airborne siliceous debris in the atmosphere.
Investigators in the aircraft engine industry might work toward developing
this database further. Collaborations between industry and academia might
facilitate accelerated progress toward understanding the nature of
high-dimensional datasets and identifying relevant exemplary compositions
for testing T/EBC materials.
