Forced-flow chemical vapor infiltration of porous ceramic materials

Forced-flow chemical vapor infiltration of porous ceramic materials

Mathematical model demonstrates an optimum flow rate for max densification (least void vol) with min. blocking of pore channels. Thermal gradient (when optimized) can assist filling. Model predictions are highly sensitive to reaction kinetics and pore size distribution.
