Ceramics – Building Materials

It is well known that thermal analysis in conjunction with mass spectroscopy finds standard application in the cement, brick, and other building material industries. Although they can also include organic materials, the main constituents of cement raw materials are calcium carbonate, gypsum, and other intricate mixtures of ceramic materials.

Combining mass spectroscopy and thermal analysis provides a tool to simulate the production process of the subsequent building material in addition to aiding in the analysis and measurement of various raw material components.

Instrumentation and Test Conditions

QMS 403 AÑolos® - STA 449 C Jupiter® was used. Here is a list of the test conditions:

. .
Temperature range RT … 1500 °C
Heating/cooling rates 10 K/min
Atmosphere Synth. air at 70 ml/min
Sample mass 16.06 mg
Crucible Pt with pierced lid
Sensor TG-DSC type S



Thermogravimetric (tG), differential scanning calorimetry (DSC), and mass spectroscopy were used to analyze raw cement material. Mass-loss steps and combined exothermal and endothermal effects were observed at 1500 °C.

The evolved gases and the cement raw material mixtures can be found with the mass spectrometer’s signals. At low temperatures, gypsum likely releases H2O, and at about 480 °C, it releases Ca (OH)2.

The temperature range for organic components' partial decomposition and burning was 300 °C to 400 °C—both the exothermal DSC peaks and the signals from the mass spectrometer support this conclusion. The evolution of CO2 suggests that CaCO3 decomposes at about 800 °C, whereas the evolution of SO2 suggests that CaS04 decomposes at the highest temperatures that can be measured.

The STA 449 F5 Jupiter for Thermogravimetry and DTA

The STA 449 F5 Jupiter from NETZSCH is a top-loading system for differential thermal analysis and thermogravimetry. The motorized furnace hoist and the top-loading principle of the balancing system allow for simple operation and sample changes.

The built-in balance’s high weighing and load range, low drift behavior, and high resolution combined with sensitive DSC capability to handle all common application tasks across a broad temperature range.

It is possible to perform true TGA and DSC measurements at sample temperatures ranging from room temperature to 1600 °C with excellent accuracy and repeatability. Flat baselines are provided by the integrated TGA-BeFlat software feature, which also removes the need for additional buoyancy correction work.

Furthermore, three integrated mass flow controllers for purge and protective gases offer the best possible control over the surrounding atmosphere of the sample.

Key Features

The STA 449 F5 Jupiter’s primary characteristics are:

  • System for topping off with a balanced design
  • Excellent performance and ease of use
  • Sensitive DSC performance
  • High range, low drift balance, and high resolution
  • The STA system’s automatic backfilling and evacuation are made possible by the AutoVac feature
  • Inbuilt mass flow regulators
  • Even with large samples, TGA measurements are feasible
  • Available with every feature of the hardware and software
