Optical Dilatometer/ Heating Microscope DIL L 74

The Optical Research Dilatometer L74 was developed to meet the demanding applications of the glass, ceramics, metal and energy industry. A high resolution CCD camera enables a visual real time analysis of the sample expansion, either as single frame or as video sequences. The big advantage of this method is that the sample is not burdened with any force. For soft samples or samples that melt during the measurement , this leads to a result, which is not distorted by the contact pressure. Several correction and analysis features are incorporated into the LIN-SEIS Evaluation Software. The...

Optical Dilatometer Liquid applications The investigation of sintering processes using pushrod dilatometers has The optical dilatometer can also be used to investigate the behavior of one disadvantage: There is always a force in z-direction that can cause melts and liquids. The contact angle as well as sphere and half sphere a certain sinter direction. The optical dilatometer instead is able to point can be detected and this can provide information about the surface measure a sinter process completely contact free and guarantees that tension of the liquid. Also the moistening behavior and...

Heating Microscope 15730 that can be used as well. It defines four characteristic tempera- tures under oxidizing atmosphere. • Observation and analysis of sintering processes • Contact angle determination Functional Principle • Microscopy at high temperatures and under different atmospheres The principle of determination of the ash melting behavior is based on a sample that is melted under defined temperature ramps. The melting temperatures for stone coal are up to 1600°C, for bio mass and wood they are at around 1200°C to 1300°C and for culm containing bio mass they are even lower. The...
