Description

The vertical research Dilatometer series L75V was developed to meet the demands of the research laboratories worldwide, including ceramics and steel industry applications.

This line of Dilatometers is capable of measurements under vacuum, oxidizing and reducing atmospheres (except 2000°C / 2400°C graphite furnace).
This series has a built in automatic pressure control with digital display. Sample pressure is very important, to accurately measure the CTE values under different pressure conditions.

A special rate controlled sintering software L75/RCS was developed to measure the Sintering behavior.

Application example:

Glass Ceramic

Application_L75_V

The dilatometric method is an excellent method to determine the thermal expansion (CTE) and the softening point of glass cera-mic materials. Besides the absolute expan-sion and the expansion coefficient (CTE) you can find the first derivative of the absolute expansion. Where the first derivative goes through zero you can determine the max. of the thermal expansion and thus the softening point of the material.
