• Volume changes • Rate controlled sintering (RCS) Dilatometry is a technique which measures the dimensional change of The entire range of LINSEIS Dilatometers enables the perfect choice for a substance as a function of temperature while the substance is sub- jected to a controlled temperature program. Many international norms such as DIN 51045, ASTM E831, ASTM E 228 and ASTM D 3386 describe this technique and the exact procedures in detail. LINSEIS Dilatometers L76, L75H, and L75V provide a powerful tool for the determination of the thermal expansion and expansion coefficient (CTE). Further...
