Measurement of Thermal Expansion
The Thermal Expansion Coefficient TEC (in the temperature range between 20-400°C), the Transition Point Td and the Dilatometric Point of Deformation Ts are the characteristic points of the glass frits.They are measured on glass rods, fired under the same conditions as they are used. For this reason it is possible to get different values for the matt frits being fired slowly or fast.The standard heating rate is 10°C/min.
Heating Microscopical Analysis
Heating microscopy allows to describe a melting process. A tablet 2 x 3 mm pressed of fine ground frit ( ) is heated with the rate 30 - 40°C/min. A change of its shape is registered on its shadow picture and characteristic points are determined on the basis of changes of the height and foot angle. Sintering point S: The temperature correspondig to the 5% contraction of the primary height.Softening point M: Round edges are visibleBall point B: The shadow looks like a sphereHalf ball point HB: Temperature, at which the foot angle equals to 90°.Flow point F: A tablet is melted down to 1/3 of its primary height
