Firing chamotte with CO2-neutral fuel

Based on the company‘s own clay quarry in Großheirath near Coburg, Germany, and through the targeted use of external raw materials, raw material solutions are produced that are individually tailored to the customer‘s requirements.

The range of raw and ground clays extends from 20 to 43% Al2O3 and firing colours from creamy white to yellow and red. The main customers are manufacturers of building ceramics and refractory products.

Argolitec is a high-purity nanoscale illite clay with outstanding properties, e.g. for technical ceramics and ceramic surfaces.

Chamotte is the most important product area at Gottfried.

These customised hard materials actively improve the production and product properties of ceramics. The chamottes are mainly used for refractory products, sanitary refractory clay and building ceramics.

The range also includes raw and calcined ground soapstone, crumb masses and contract processing.

In spring, Gottfried plans to switch the firing of chamotte and other minerals in rotary kilns from fossil fuels such as oil and coal to biogenic fuels such as wood. To this end, an extensive plant for processing waste wood into a defined wood flour will soon be put into operation. Another important step towards efficient and sustainable raw material production.

In Thansüß near Amberg, Gottfried operates a pegmatite mine and a mineral grinding plant. The white-firing potash feldspar sand is a classic basic raw material for porcelain, sanitary ceramics and tiles. Other minerals, such as sodium feldspar, can also be combined as required and ground iron-free. A washed quality is characterised by particularly low iron and titanium contents.

Pegmatite in special grain sizes has proven itself as a grogging agent in mixes for light-fired clinker bricks and roof tiles.
