1. TGA alumina crucible is made of high-purity alumina (Al2O3), which has excellent chemical stability and minimizes interactions with reactive substances. 2. TGA alumina crucible is corrosion-resistant, wear-resistant, and abrasion resistant, making it very durable when reused in high-temperature applications. 3. The low thermal expansion rate and excellent thermal shock resistance of TGA alumina crucibles further improve their reliability in strict thermal cycles, ensuring precise and consistent performance.
