Carbolite Gero 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.
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.
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.
During the heat treatment process, the 3D-printed components were treated in the same furnace. The X-shaped sample experienced a weight loss of approximately 6.5%, while the rectangular-shaped sample showed a weight loss of about 11.1%.
The HTF furnaces ensures exceptional temperature uniformity with its advanced design, high-quality elements, and superior thermal insulation for minimal heat loss and even heat distribution.
