Testes we carry out on raw materials and finished products / Analysis methods

Raw materials and finished products can be tested for conformity to a range of standards.

Raw materials

• chemical analysis / X-ray fluorescence spectroscopy (XRF) (calibration - by certified reference materials, by internal standards);
• loss on ignition (1000 OC);
• particle size distribution
• screen residue (wet; dry)
• screen analysis(wet; dry);
• moisture content;
• solids content;
• ph-value (10% solid content);
• plasticity (Pfefferkorn);
• dry modulus of rupture (drying temperature of 100 OC);
• casting behaviuor (Lehmann viscometer)
  • optimized deflocculant addition
  • outflow time (volume 100 ml)
  • casting rate (30 min);
• contraction (drying, firing, total);
• refractoriness;
• compactness characteristics (fired samples):
  • water absorption
  • apparent porosity
  • apparent density; true density.

Finished product

• chemical analysis / X-ray fluorescence spectroscopy (XRF) (calibration - by certified reference materials, by internal standards);
• water absorption;
• porosity;
• dimensions / dimensional tolerances;
• thermal shock resistance;
• modulus of rupture and compressive strength.
