Sample preparation in the Ceramics Sector
Quality and process standards assurance
Clays, chamottes and ceramics are used in various ways and must therefore be in accordance with different degrees of quality standards. These quality standards have especially in recent years gained in significance for the processing industry and therefore at the same time for the producers of such chamottes and ceramics. Based on the risen quality standards more and more often, the crude materials and also the finished products are more precisely analyzed. Considered are the classic chemical and physical variables, as well as the technological data of crude materials and finished parts like for example Geochemical and mineralogical composition, Thermal endurance, Heat conductance & coefficient of thermal expansion, Breaking resistance & flexural strength.
Based on the very inhomogeneous composition of clays, which are mostly composed of various clay minerals, a sample preparation in a clay and ceramics laboratory for further analytical use via x-ray fluorescence, atomic absorption spectrometer, or inductively coupled plasma emission spectrometry, or AES is mandatory, since the chemical composition of the crude materials has a decisive influence on the technical abilities of the finished products.
Due to these facts, Goerg & Schneider, one of the leading producers for crude clays, milling clays, chamottes and ceramic masses, chose the FRITSCH Planetary Mono Mill PULVERISETTE 6 with an agate grinding set, for the efficient and time saving sample preparation.
