Ceramic Sintering – High Performance Firing Solutions
At Hobersal, we specialize in advanced thermal solutions designed for the precision and reliability required in technical ceramic sintering. Our furnaces are developed to meet the demanding needs of modern industries where quality, consistency, and control are non-negotiable.
What is Ceramic Sintering?
Ceramic sintering is a critical process in the transformation of shaped ceramic powders into solid, durable components. Through controlled high-temperature heating, particles bond together, increasing density and enhancing mechanical, thermal, and electrical properties without reaching the melting point. The process is key for producing technical ceramics used in high-performance sectors.
Process Stages: Debinding and Sintering
-
Debinding Phase:
Before sintering, ceramic green bodies often contain organic binders that must be removed. This step involves heating at lower temperatures to cleanly eliminate volatile substances, avoiding structural defects in the final product. -
Sintering Phase:
Following debinding, the material is heated at high temperatures—often up to 1800 °C—under carefully controlled conditions to achieve full densification and functional properties.

Accessories
Gas supply system
Gas supply system 1, allows gas to be injected at the desired temperature by means of a controller and thermocouple, includes a choice of two flowmeters, maximum working pressure 0.2bar.
Afterburner
In ceramic debinding processes, an afterburner is used to oxidize volatile organic compounds released from binders, converting them into safer gases like CO₂, NOx, and H₂O. This ensures clean emissions and prevents the release of toxic or flammable substances.
Condensate trap
A condensate trap in ceramic debinding furnaces is used to capture and remove liquid byproducts (like water, oils, or condensed organics) from the gases released during binder removal. It helps protect the exhaust system, prevent blockages, and reduce harmful emissions by condensing volatile substances before they exit the furnace.
Protective gas box
Protective Gas Boxes for working under protective, inert atmosphere, nitriding and carburising salts..
