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
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.
