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.
