COMPOSITION AND SHAPING OF A CERAMIC MATERIAL WITH LOW THERMAL EXPANSION COEFFICIENT AND HIGH RESISTANCE TO THERMAL SHOCK

The present invention is a composition and shaping of a ceramic material comprising at least one frit and at least one inorganic raw material. Some of the advantages are that said material requires a heat treatment no higher than 1180°C, that the duration of said heat treatment does not exceed 60 mi...

Beschreibung
Zusammenfassung:	The present invention is a composition and shaping of a ceramic material comprising at least one frit and at least one inorganic raw material. Some of the advantages are that said material requires a heat treatment no higher than 1180°C, that the duration of said heat treatment does not exceed 60 minutes, that the thermal expansion coefficient after the heat treatment is less than 25 x10-7°C-1in the temperature range 25°C to 500°C and that the material exhibits a high resistance to thermal shock, withstanding at least 10 consecutive thermal shock cycles between 600°C and 25°C without forming cracks or structural changes. The ceramic material composition is shaped by uniaxial pressing, band pressing, pour moulding, extrusion, injection moulding or lamination.
