STA 449 F1 Jupiter®-Application examples
Water evaporation in Al2O3- excellent stability
Heating the alumina powder to 400 ° C (initial mass of 120.0mg) resulted in a weight loss of 16.50mg, mainly due to the evaporation of water, corresponding to the endothermic peak on the DSC curve. During the 50 hour constant temperature process, the mass change was only 11 micrograms, demonstrating excellent stability of the balance system.

Reduction of Manganese Oxide
Manganese oxide (MnO2) is commonly used as an oxidant in the chemical field and as a cathode material in the battery industry. In the following STA measurement spectrum, there are two weight loss steps at approximately 600 ° C and 950 ° C, which are due to the reduction of MnO2 to Mn2O3 and ultimately to Mn3O4. The corresponding weight loss of 9.20% and 3.07% are in good agreement with the theoretical values, reflecting the high accuracy of the weighing system. On the DSC curve, there are two endothermic peaks corresponding to enthalpy of 432 J/g and 180 J/g, respectively. The DSC endothermic peak at 1200 ° C is a reversible structural transformation without corresponding weight loss process. The corresponding reversal during the cooling process (dotted line) corresponds to the exothermic peak at 1148 ° C.

Decomposition of basic ferric sulfate
Basic iron sulfate (Fe (OH) SO4) is the basic raw material for synthesizing iron oxide and can be used as a pigment or magnetic storage medium. The commonly referred to ferromagnetic fluid contains superparamagnetic iron oxide nanoparticles, which can serve as contrast agents for magnetic resonance imaging. When the temperature is below 600 ° C, according to the results of STA-MS combined testing, there are two steps of dehydration process, corresponding to the peak with a mass number of 18 on the mass spectrum curve. Between 600 ° C and 800 ° C, SO2 and O2 are generated, corresponding to peaks with mass numbers of 64 and 32. The final product is Fe2O3 (hematite).

Building materials: phase transition of gypsum and quartz sand mixture
Gypsum and quartz sand are often used in gypsum and plaster. In this example, the gypsum dihydrate CaSO4 * 2H2O component in the sample undergoes a two-step dehydration process before 200 ° C, and finally transforms into anhydrous gypsum CaSO4 through the hemihydrate CaSO4 * 1/2H2O, with a total endothermic enthalpy of 122 J/g. Quantitative analysis shows that the sample contains 23.4% gypsum dihydrate. Anhydrous gypsum releases 18.3 J/g of heat between approximately 300 ° C and 450 ° C, forming β - CaSO4. The endothermic effect at an initial temperature of 573 ° C is due to the α →β phase transition in the structure of quartz (crystalline SiO2).

Phase diagram of alloys
Pt0.89Au0.1OIr0.01 is a dental alloy commonly used for inlays, crowns, and bridges. Dental alloys must have strength, formability, corrosion resistance, and biocompatibility. The test results show that during the heating process, there is an endothermic phenomenon on the DSC curve (solid line) at the extrapolated starting temperature of 1659 ° C, mainly due to the melting process, with a enthalpy value of 88J/g. During the cooling process, the DSC curve (dashed line) shows an exothermic peak (peak temperature 1684 ° C) at the starting temperature of 1685 ° C, mainly due to the crystallization process of the alloy, with a enthalpy value of -87J/g. At the highest temperature, there is a weight loss of 0.05%, mainly due to the onset of volatilization.

Plastic
Plastic bottles, textile fibers, and films (such as packaging food) are the most common applications of high polymer PET (polyethylene terephthalate). The STA test results show that under N2 atmosphere, there is a step in the DSC curve before 100 ° C, mainly due to glass transition, and an increase in specific heat of 0.35 J/(g * K). The endothermic peak at 81 ° C is mainly due to relaxation phenomenon. The exothermic peak at 131 ° C is mainly due to the cold crystallization process. The endothermic peak at 255 ° C is the melting process. After 360 ° C, the sample began to decompose, accompanied by a 79.5% weight loss.
