The new installed scanning electron microscope (SEM) JEOL IT-300 LV at the Institute of Nonferrous Metallurgy/University of Leoben is a tungsten-filament based unit with high- and low vacuum mode (up to 650 Pa for low conductive materials) and is equipped with a large chamber and heavy duty stage for samples up to 200 mm in diameter and 2 kg in weight as well as a lock for fast sample charging.
The SEM is combined with a last generation-type of 50mm² energy dispersive X-Ray detector (EDX/EDS) from Oxford Instruments, which allows spot-scans and mappings with high scanning rates and resolutions at short operation time.
A really outstanding feature of this unit is the heating stage from Kammrath & Weiss with a maximum reachable temperature of 1500°C, 5K/min heating rate and approx. 10x10x3 mm specimen size for in-situ-investigations on different research areas like e.g. materials science or recycling of complex secondary raw materials.

Methods & Expertise for Research Infrastructure
This unit is used for material science, damage analyses as well as characterisation of various raw-, recycling- and residue materials. The tasks vary from simple surface imaging over spot-scans and mappings up to heating stage experiments.
