To describe the material properties and to give a comprehensive understanding of the material behaviour under application conditions, the materials' refractoriness must be studied using appropriate methods from four disciplines:

  • Chemistry
  • Physics
  • Mineralogy
  • High temperature behaviour

Only those who master all disciplines can make reliable statements about material performance at high temperatures, under corrosive environmental conditions with simultaneous mechanical stress, and changing mineralogical compositions at the same time.

It is often necessary to complete standard test methods by specially developed techniques to determine precisely reproducible characteristic values by means of laboratory tests. This expertise ensures sustainable and comprehensive understanding of the refractoriness of raw materials, products and system solutions.

We provide this know-how through advice and targeted communication with our clients. By doing so, we effectively serve our customers to come up with their needs.
