Alumina Crucibles

Alumina crucibles are particularly ideal for this purpose since they have excellent chemical resistance, low porosity, and can withstand high temperatures. Additionally, these crucibles do not react with the samples tested within them, accurately providing precise results!

Alumina Crucibles in Thermal Analysis Measurements

Thermal analysis crucible made of alumina have been extensively studied and found to be the preferred choice for obtaining accurate results in DSC measurements. Crucibles serve as a container for samples during such measurements and help ensure that the sensor is not contaminated. Furthermore, considering relevant factors before measuring thermal analysis with an alumina crucible can help improve the quality of measurement results.

Alumina crucibles are essential tools used in thermal analysis techniques such as Differential Scanning Calorimetry (DSC), Thermo-Gravimetric Analysis (TGA), and high temperature Differential Thermal Analysis (DTA). The crucibles offer superior chemical compatibility and can be used in a wide range of temperatures, up to 2000°C when connected to an appropriate furnace. The alumina material offers excellent thermal shock and corrosion resistance and is therefore ideal for demanding laboratory applications.

Thermal analysis of alumina crucibles allows for high resolution results due to their low mass. Keeping sample purity is important when using an alumina crucible for thermal analysis. This is due to the fact that any potential interactions between the sample and the crucible could affect the results of the analysis. Therefore, it is essential to ensure that there is no interference in order for accurate results to be obtained.

How to Choose an Alumina Crucible

Thermal analysis of an alumina crucible involves heating up the crucible, then measuring the temperature and recording its properties as it cools. This process can be used to evaluate how a material responds to temperature changes and determine its thermal conductivity, specific heat capacity and thermal expansion coefficient.

In order to accurately perform thermal analysis with an alumina crucible, the flatness of its surface should be ensured. Having a perfectly flat surface ensures good thermal contact and will prevent any unwanted artifacts from appearing in the results.

When it comes to accurate thermal analysis, the alumina crucible plays a key role. The selection of the crucible should be based on several factors such as thermal shock resistance, chemical inertness, allowable furnace temperature, sample size, and compatibility with environment.
