STA 449 F5 Jupiter®-Application examples
Calcium oxalate monohydrate
Calcium oxalate monohydrate
In the field of thermal analysis, calcium oxalate monohydrate (CaC2O4-H2O) is often used to verify the accuracy of TGA signals. This substance has high stability and is basically non hygroscopic, making it an ideal material for verifying the performance of thermal balance.
The following figure shows the TGA and DSC curves of CaC2O4-H2O in the temperature range of room temperature to 1000 ℃. The first stage of weight loss is the dehydration process, where the sample transforms into anhydrous calcium oxalate (CaC2O4) after dehydration. The second stage of weight loss step is caused by the release of CO, representing the transition from calcium oxalate to calcium carbonate (CaCO3). At temperatures above 700 ℃, calcium carbonate decomposes and releases CO2; The residual mass is calcium oxide (CaO). The experimentally measured weight loss is in good agreement with the theoretical value (deviation<1%). This proves that STA 449 F5 Jupiter®Thermobalance has high measurement accuracy.

The melting point of palladium
The biggest use of palladium (Pd) today is as a catalytic converter. In addition, it is often used in other fields such as dentistry, aircraft spark plugs, surgical instruments, electrical contact materials, etc. Palladium does not react with oxygen at room temperature, but when heated to 800 ° C in an air atmosphere, it forms a very thin layer of palladium (II) oxide (PdO). This figure shows the measurement of Pd conducted on STA, with a maximum temperature of 1600 ° C. The blue DSC curve shows the melting process, with a enthalpy of 158 J/g and a melting starting point of 1554 ° C. These two values are very close to the theoretical values of pure Pd, with a deviation of<1%. The green TG curve shows that there was no weight loss before and after melting; This proves the high purity of the metal and the vacuum tightness of the system.

Thermogravimetric testing of weathered rocks
Bentonite is a type of clay mainly composed of Jiaoling stone, which is praised for its adsorption ability. This mineral material is often used in fields such as adhesives and purifiers. The green curve in this figure represents TG, the green dotted line represents DTG, and the blue curve represents DSC curve. The first weight loss step (DSC peak temperature of 96 ℃) is caused by the release of water, followed by a small weight loss process of 0.6%, which is likely caused by the cracking of organic impurities, indicating the presence of a small amount of pyrite impurities in the material. Above 600 ℃, water is released from the porphyritic rock structure (DTG peak temperatures of 685 ℃ and 708 ℃). The exothermic peak of the DSC curve at 969 ℃ represents the phase transition of the mineral. The most likely reason for the endothermic peak at 1181 ℃ is partial melting.

Zirconia adhesive burned out
Zirconia is the most common ceramic material. During the heating process, it undergoes a destructive phase transition. By adding a small amount of yttrium oxide, these phase transitions can be eliminated, resulting in materials with excellent thermal, mechanical, and electrical properties.
The measurement temperature range in the following figure is from room temperature to 1200 ℃, and the green curve is the TG curve. There are two small weight loss processes before 450 ℃, with a total weight loss of 3.4%, which is consistent with the two exothermic peaks at 197 ℃ and 399 ℃ on the blue DSC curve. These effects are caused by the burning out of binders in ceramic materials, resulting in higher calorific values and larger peak shapes. The small DSC endothermic peak near 67 ℃ is caused by the melting of the adhesive.

Corrosion-resistant alloy
Hastelloy is a nickel chromium molybdenum tungsten alloy that exhibits excellent high-temperature stability and good ductility and corrosion resistance even at high temperatures. It is often used in combustible gas desulfurization, chemical industry, and burn sterilization. The heating DSC (blue) curve in the figure shows that the melting of Hastelloy sample (alloy 22) occurred at 1358 ℃ (extrapolated starting point) with a enthalpy of 165J/g. The cooling DSC (red) curve shows that the crystallization process occurs at 1351 ℃ (extrapolated starting point), and its enthalpy change is almost identical to the melting process. The TG curves for temperature rise and fall are all horizontal lines, and no weight loss or weight gain caused by oxidation was observed.
