Science behind BIOLOX delta Material
BIOLOX delta is an aluminum oxide matrix composite ceramic consisting of approx. 82% alumina (Al2O3), 17% zirconia (ZrO2) and other trace elements (percent by volume). The pink color is due to the chromium oxide (Cr2O3).
Alumina provides the material’s hardness and wear resistance, while zirconia, together with other additives, provides improved mechanical properties. These properties are achieved, among other things, by means of the high strength, the high density of the material and the very small grain size of the alumina matrix.1
The result is a high-performance ceramic that offers the same advantages as BIOLOX forte: excellent biocompatibility, low wear, high hardness, outstanding chemical and hydrothermal stability with better mechanical properties, particularly toughness.1
