5. Thermocouple
6. Usable space
MoSi2U-shaped heating elements are installed in a vertical, hanging position within the HTF. The heat is insulated using ceramic fiber boards, layered with an appropriate thickness to enhance temperature uniformity. The maximum temperature of these boards is chosen based on the furnace's maximum temperature requirements. Water cooling is unnecessary due to the low thermal conductivity of the insulation material. The system is externally cooled by ambient air convection within the outer case.
MoSi2 heating elements are ideal for high-temperature processes, as they naturally form a protective oxide layer at elevated temperatures. The HTF chamber furnace is distinguished by its exceptional temperature uniformity and compact design.

Debinding & sintering
Carbolite HTF furnaces may be equipped with debinding and sintering options to accommodate a range of technical ceramic applications A thermally induced decomposition and evaporation of the binder occurs due to gas flow through the HTF furnace during the debinding phase. The gas flow guides vapours to leave the sample.
The sintering of oxide ceramics in an HTF 1700°C or 1800°C furnace is a critical process in materials engineering, essential for achieving optimal mechanical and structural properties in ceramic components. This high-temperature sintering, particularly relevant for materials like alumina and zirconia, optimizes microstructural characteristics, enhancing performance in demanding applications.
High quality MoSi2 heating elements and preheated air inlet.
Optimised pre-heated air flow for efficient binder removal.
For safe combustion of binder gases an active propane gas afterburner can be provided.
Sinter run in HTF 18/64
Disclaimer: The information presented shows typical performance. Furnace load ~ 8kg.
Loading: The ceramic is placed on a sintering tray in the HTF furnace, using a tray that withstands high temperatures without reacting with the ceramic.
Ramp-Up: The furnace's temperature is methodically increased to 1800°C, with a controlled profile to prevent thermal shock and ensure even heating, possibly pausing at certain temperatures for stress relief.
Soak: At 1800°C, the ceramic undergoes a critical soak, allowing particles to merge through diffusion, enhancing density and growth.
Cool Down: Following the soak, the furnace cools to room temperature at a rate that prevents thermal stress, avoiding cracks or deformation in the ceramic.
Cooling options
The cool down phase in sintering oxide ceramics, is crucial for maintaining structural integrity and achieving desired properties. By utilising the HTF furnace's pre-heated air inlet blower options the user gains flexibility for their sintering processes. This feature allows precise control of cooling from sintering temperatures (1700 or 1800°C) to room temperature, preventing thermal gradients and associated stresses that could damage the ceramic.
For complex shapes or materials prone to thermal shock, step cooling can be used. With the HTF furnace step cooling can be optimised to minimize thermal stress risks by holding at intermediate temperatures to equalize internal and external temperatures. The HTF furnace can be used to tailor the cool down to each ceramic's needs ensures high-quality components with optimal properties.
