Heating Microscope

A high-temperature heating microscope and optical dilatometer from Hesse Instruments is used for the fast and effective optimization of sintering temperatures and curves. With this, sintering temperatures and temperature programs can be determined in advance saving time and resources, as a variation of the mix design can be quickly realized with little effort using smallest sample quantities.

Rotary Furnace

Subsequent to the first determination of the sintering temperature / curve in the high temperature heating microscope, further sintering tests can be carried out in the rotary kiln. Two laboratory rotary kilns with a maximum temperature of 1500 ° C are available for this purpose. The laboratory furnaces each have a SiC ceramic tube for quick replacement when using new raw materials and are equipped with two respectively three independently controllable heating zones. In these rotary furnaces, the optimization of the sintering process can be carried out on laboratory scale.


In particular, granulated bulk materials are often sintered in rotary kilns. Here, so-called "proppants" for the oil and gas industry are produced on a laboratory scale. The process parameters developed here again serve to scale up the process in production plants. Other tasks require different tools. In addition to the rotary kilns, a chamber kiln up to 1300 ° C is available for a wide variety of tasks.
