Ceramics & Glass
Knowledge of such properties as the thermal length change for the SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. sintering of technical ceramics, Phase TransitionsThe term phase transition (or phase change) is most commonly used to describe transitions between the solid, liquid and gaseous states.phase transitions and the Specific Heat Capacity (cp)Heat capacity is a material-specific physical quantity, determined by the amount of heat supplied to specimen, divided by the resulting temperature increase. The specific heat capacity is related to a unit mass of the specimen.specific heat capacity for modified glass, and the precise Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity values for inorganic building materials is of high practical importance in this field.
In particular, Simultaneous Thermal Analysis (STA) is ideal for investigating issues such as the Glass Transition TemperatureThe glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery.glass transition temperature of modified glass, the binder burnout of a polymer binder, the dehydration of ceramic materials and the Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition behavior of inorganic building materials – also via the subsequent application of evolved gas analysis (QMS).
Dilatometryis the method of choice for investigating expansion and shrinkage behavior during ceramic sintering.
LFA and HFM are versatile methods for the precise determination of thermal conductivity.
Important properties of refractories are the bending strength at elevated temperatures, softening under load, and creep in compression. To determine these values, instruments specially tailored to this material group – such as the apparatus for determining refractoriness under load (RUL) and creep in compression (CIC) or the apparatus for testing hot modulus of rupture (HMOR) – are available.
