Complex Analyses

Since 1992, we have been supporting the ceramic industry with external laboratory capacities and became a reliable partner of many brickworks. This includes the monitoring of the raw material production as well as the mass optimization and product development.

Self Monitoring / External Survey

External raw material quality controls for both raw material supplier as well as brickworks. Individual analytical proceeding including particle-size distribution, chemical-mineralogical and ceramic analyses as well as microscopic tests to check for interfering components > 250 µm. Recommended test frequency: one complete analysis per 1,000 - 5,000 tons of raw material depending on the homogeneity.

Causal Damage Analysis

Mineralogical and microscopic/scanning electron microscopic identification of the damage as well as a detailed cause analysis with a retracing to the mining area. Typical complex analysis in case of bloom defects, blistering, texture-, drying-, heating- or cooling-cracks, reduction cores and color variation.

Mass Optimization / Development of Mass Composition

Substitution of individual mass components by alternative raw materials to enhance productivity/lower the costs and/or improve product characteristics. Comprehensive investigations on individual mass components and their compositions. After laboratory phase, conception and monitoring of production trials. 

Product Development

Prearrangement of several test series for the development of new brick products. Focus: facing bricks/clinker bricks (color development) and backing bricks (ceramic body density, thermal conductivity, compressive strength). After laboratory phase, conception and monitoring of production trials. 

Suitability Tests

During the production and processing of mineral raw materials, large quantities of waste materials are accumulated. Mostly, these materials are argillaceous residues, clay mineral filter cakes and rock dust/fillers. Pursuing the objective of a long-term integration of these raw material potentials in ceramic industry, we offer costumer oriented suitability tests. Focus: sand/gravel and aggregate industry.
