1.TGA alumina crucible is made of high-purity alumina (Al2O3).
2.TGA alumina crucible is corrosion-resistant, wear-resistant, and wear-resistant.
3. Accept customized sizes.
4. Large stock and fast delivery.
Alumina crucibles do not melt or deform at the high temperatures required for experiments. They are chemically inert to the vast majority of samples and do not interfere with reactions.
Alumina crucibles exhibit good thermal response characteristics (low heat capacity, moderate thermal conductivity), ensuring the sensitivity and accuracy of temperature control and measurement.
They are suitable for multiple atmospheres and various sample types, while also having sufficient mechanical strength, offering good cost-performance ratio.
Applications of TGA Alumina Crucible
Suitable for multiple atmospheres: Alumina crucibles are capable of performing well in air (oxidizing atmosphere), nitrogen, argon (inert atmosphere), and certain weakly reducing atmospheres (such as nitrogen-hydrogen mixtures). Alumina crucibles compatibility with different atmospheres is superior to many other ceramic or metal crucibles (e.g., platinum may be damaged in reducing atmospheres).
Suitable for various types of samples: These include, but are not limited to, polymer materials, organic compounds, metal oxides, ceramic precursors, catalysts, pharmaceuticals, and food. Alumina crucibles can be used as long as the samples do not undergo significant reactions with alumina.
