Aluminum Titanate — Sintering

One use of aluminum titanate is as a carrier material for catalytic converters in the automobile industry. Shown here is the measurement of an aluminum titanate green body in the temperature range from RT to 1450°C with a subsequent isothermal line at 1450°C of 7 hours. During the heating, shrinkage of 12.7% is observed. The sintering takes place in 2 steps with a maximum sintering rate of 0.31%/min. In the subsequent isothermal phase, further shrinkage of 0.6% occurs. To optimize the sintering process, an RCS measurement (rate controlled sintering; optionally available) can additionally be carried out. (measurement with TMA 402 F1/F3 Hyperion®)
