ELS-MDF: Microscope, Dilatometer, Fleximeter

ELS-MDF is the new contact-less thermal analysis instrument able to reproduce industrial heating cycles while unifying the following measurement techniques:

  • Heating Microscope to study the fusibility of materials (ceramic raw materials, glazes, frits, ashes, glasses);
  • Optical Dilatometer to study the coefficient of thermal expansion and sintering behaviour during firing;
  • Optical Fleximeter to study the piroplasticity and the state of tension between the glaze and the ceramic body.

The instrument reproduces in laboratory the industrial firing cycle:

  • Up to 80°C/min
  • Up to 1400°C
  • Fast cooling

Ceramic process simulation

How to determine the best firing cycle?

The Optical Dilatometer is the best instrument to study the sinterization and to determine the best firing cycle avoiding any risk of damage thanks its optical technology.

How to assess the stability interval of a ceramic body?

Take advantage of the Optical Dilatometer to study of the interval of stability of a ceramic body avoiding the risk of bloating.

Take advantage of the Optical Fleximeter to study the piroplasticity of the ceramic body, which is its tendency to deform under its own weight.

How to verify the compatibility between a ceramic body and a glaze?

The heating Microscope can indentify the softening temperature, which must be suitable for the ceramic firing cycle.

The studies run thanks to the Optical Dilatometer can match those run taking advantage of the Optical Fleximeterto determine the state of tension in final products.

Reliable quality control thanks to precise and repeatable measurements

How to study the fusibility of raw materials and glazes?

The heating Microscope can identify the softening and the melting point. It is really useful to study the fusibility of both raw materials and glazes

How long does it take to cool until room temperature?

Both the refracotry kiln and the heating elements are designed to heat and cool in the short time. The laboratory techincians can use also an electric fan to cool the instrument.

How many CTE (COE) can I determine per day?

ELS-MDF can run up to five dilatometry tests per day thanks to the optical system and the heating equipment.

How many microscope samples can I analyze at the same time?

ELS-MDF Heating Microscope can run up to four simultaneous analyses.

Heating Microscope

The Heating Microscope measurement technique, included in ELS-MDF:

  • Is able to store images of the test piece at predetermined temperature or time intervals;
  • Works in the range between 25°C and 1600°C;
  • Automatically identifies characteristic shapes.

ELS is equipped also with different kind of analysers:

  • A heating microscope that works up to 1750°C;
  • A heating microscope that can analyses up to 8 samples at the same time.

The applications of heating microscopes include:

  • Identifications of charactristic shapes of glasses, glazes and frits;
  • Determination of melting point;
  • Comparison between different kind of samples that undergo the same thermal cycle;
  • The study of behaviour of mold powders for continuous casting.

Case study: Fusibility of glazes, ceramic bodies and frits

Optical Dilatometer

The Optical Dilatometer measurement technique is included in the ELS-MDF instrument.

  • Is based on two optics which are framing both the ends of the sample that is free to expand in both directions;

  • Allows to extend the range of research to temperatures higher than the softening point;

  • Works in the range between 25°C and 1600°C.

The applications of optical dilatometry include:

  • Measurement of thermal expansion. ELS-MDF can be used also to measure the thermal expansion of ultra-thin materials and soften ones;
  • Sintering studies;
  • Optimization of the firing cycle of ceramic bodies;
  • Quality control of raw materials.

Case studies:

Optical Fleximeter

The Optical Fleximeter measurement technique, included in ELS-MDF instrument:

  • Performs flexion measurements on a sample placed on two holding rods, 70mm spaced;
  • Is equipped with a camera that frames the center of the sample. It is free to move downwards or upwards during the test.

The applications of fleximeter include:

  • Measurement of ceramic body pyroplasticity
  • Study of deformation after firing of glazed ceramic materials and identification of coupling temperature
  • Bending of green tiles due to consecutive applications of water

Case studies:

Laboratory

The laboratory run all common analyses concernign ELS-MDF. In addition, it is equipped with another wide range of instruments.

TGA-DTA-MS

Thermogravimetric Analysis (TGA) measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material’s thermal stability and composition.

Differential thermal analysis (DTA) is a thermal analysis technique that measures the difference in temperature between a sample and an inert reference material, when they both are heated under the same controlled temperature conditions.

Evolved gas analysis involves the qualitative investigation of the evolved gas products from a TGA experiment. These products are generally the result of decomposition, but can also evolve from desorption, evaporation or chemical reaction.

Evolved gas analysis is typically performed by interfacing a mass spectrometer (MS) or Fourier transform infrared spectrometer (FTIR) to the exit port of the TGA furnace.

Our lab can run simultaneous TGA-DTA-MS analyses using a thermobalance equipped with a mass spectrometer.

MDF: Microscope Dilatometer Fleximeter

Expert Lab Service

Jan 2019 – Present Italia
Since 2019 ELS started to develop and sell new optical laboratory equipment, characterised by the fact that all the measurements are made with no contact with the specimen. The new machines show an innovative design, both in their hardware and in their software. The new instruments are designed to reach higher performances than before in the thermomechanical field. For example, they can reproduce complex industrial firing cycles (flash heating and flash cooling) and the heating microscope can run up to four simultaneous analyses.
