Understanding TGA (Thermogravimetric Analysis)
Thermogravimetric Analysis (TGA) is a thermal analysis technique that measures the mass change of a sample as a function of temperature or time. These alumina crucibles provide an inert environment for accurate mass measurements during thermal decomposition, oxidation, and other thermal processes.
Why Alumina Crucibles for TGA?
- Chemical Inertness: Alumina does not react with most samples
- High Temperature Stability: Maintains integrity at extreme temperatures
- Low Thermal Expansion: Minimizes measurement errors
- Excellent Thermal Conductivity: Ensures uniform sample heating

Frequently Asked Questions
Q: What's the difference between TGA and DSC crucibles?
A: TGA crucibles are typically open and designed for mass change measurements, while DSC crucibles often have lids and focus on heat flow measurements. This crucible is optimized for TGA applications.
Q: Can I use these crucibles for other thermal analysis techniques?
A: While designed for TGA, these crucibles can be used for other high-temperature applications, but always verify compatibility with your specific instrument and analysis requirements.
Q: How many times can I reuse these crucibles?
A: With proper care and cleaning, these crucibles can be reused many times. Replace when you notice damage, contamination, or dimensional changes.
