ytstabilisators
Ytstabilisators, often referred to as yttria-stabilized zirconia (YSZ), are a class of ceramic materials derived from zirconium dioxide (ZrO2) with the addition of yttrium oxide (Y2O3). The primary function of adding yttria is to stabilize the tetragonal phase of zirconia at room temperature. Pure zirconium dioxide undergoes phase transitions upon heating and cooling, which can lead to cracking and failure. Yttria, when incorporated in specific concentrations, prevents these undesirable phase transformations, resulting in a much more robust and durable material.
The properties of YSZ can be tailored by varying the concentration of yttria. Common compositions include 3
Ytstabilisators find extensive use in various high-performance fields. They are crucial in the biomedical industry for
