Description

The horizontal research Dilatometer series L75H 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 graphite furnace). This series has built in an 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.

The following physical properties can be measured:

CTE, Linear Thermal Expansion, Alpha Physical, Sintering Temperature, Phase Transformations, Softening Points, Decomposition Temperatures, Glass Transition Temperatures
Application example:

Ceramics industry / Powder metallurgy

L75 H- Application

In production processes of high-tech ceramics (Al2O3) a simulation of the sintering process is of special interest. When using the optional software package RCS (rate controlled sintering) it is possible to program controlled sintering in the Dilatometer as per the PALMOUR III theory. Picture shows the sintering process of ZrO2. Here the final density of 100% is achieved. The initial heating rate decrease as the final density is reached.
