The base materials for the manufacture of hard ceramics are high-grade clays, kaolins, feldspars, and pure quartz sand. These materials are finely ground and mixed according to a defined recipe to form a ceramic mass with very high wear resistance properties. The controlled production process safeguards the excellent properties of the hard ceramic, such as:
– High abrasion resistance
– High compressive strength and resistance to nearly all acids and alkalis (with the exception of hydrofluoric acids and their compounds)
– Very good thermal shock resistance
– Temperature resistance up to +500°C
– Frost resistant and corrosion free
– Extremely smooth surface, thus preventing bulk materials from caking, bridging, and clogging
