Test Firing

Fraunhofer-Center HTL’s pilot plant facilities include various furnaces for the heat treatment of oxide and non-oxide ceramic, metallic samples and components.The following processes can be carried out in different atmospheres and optimized in close cooperation with the customer: debinding, pyrolysis, graphitization, melt infiltration (particularly with silicon) and sintering.Various furnaces are connected to a thermal afterburner, making it possible to carry out processes that produce large volumes of condensates. In addition to test firing, quality assurance can be performed on all samples and components before and after firing by means of computerized tomography, mechanical characterization, density measurements, etc., in order to document any possible changes or damages to the material.

Our Services:

  • Carrying out test and on-demand firing according to customer specifications up to a maximum temperature of 2400°C in defined atmospheres, such as vacuum, inert gas, hydrogen, and air
  • Furnace volumes up to 385 liters; suitable for manufacturing large individual components or small-scale series
  • Maximum size of components: 800 x 800 x 600 mm³
  • Optimization of heat treatment processes, such as debinding and sintering
  • Process control and process reliability through PLC, visual monitoring and measurement of the composition of the furnace atmosphere
  • Process documentation and final inspection of components according to the customer’s request
