Frequently Asked Questions
What are miniature alumina crucibles used for? Why choose 99% high-purity alumina for thermal analysis?
Miniature alumina crucibles are precision experimental tools specifically designed for thermal analysis instruments like TGA, DSC, and DTA. They are widely used in the thermal property research of polymers, ceramics, composites, and battery materials. Choosing 99% high-purity alumina ensures exceptional high-temperature resistance, a low thermal expansion coefficient, and strong chemical stability. This enables the crucible to easily withstand rapid heating and cooling cycles without cracking, ensuring the test data is highly sensitive and accurate.
How does a miniature design improve thermal analysis? What crucible sizes and volumes are available?
A miniature, lightweight crucible design significantly reduces sample consumption while perfectly fitting the sample chamber size of thermal analyzers. This structure provides a fast thermal response and uniform heating, which directly improves the accuracy and sensitivity of the thermal analysis. To meet different experimental requirements, Innovacera offers these crucibles in various precision sizes, typically ranging from 15μL to 30μL in volume, with outer diameters (OD) starting from 2.9mm up to 6mm.
