Results and discussion

Melting / freezing point
Melting / freezing pt.:
> 650 °C

Any other information on results incl. tables

The TGA shows a loss of 47% below 170°C attributed to water. Between 170 and 600°C there is a non-specific weight loss of 8%.

The DTA does not show any endothermal event indicative of melt.

A visual inspection of the material after TGA shows a free-flowing, white powder.

Applicant's summary and conclusion

Conclusions:
AlASP does not undergo any first order transition below 650 °C that may be attributed to melt.
