Low-Temperature Plasma Treatment of Aluminum Oxide and Its Chemical Properties

Alumina-based ceramics arc widely used in reconstructive surgery due to their excellent biocompatibility and excellent mechanical properties. However, an important role is played by the surface treatment of the material, which improves wettability and adhesion properties. Plasma treatment does not affect the morphological properties of the material, but changes the acidity of its solutions or suspensions. The work shows the effect of low-temperature plasma treatment of powder and aluminum oxide sintered samples on their chemical properties. It is shown that plasma treatment changes the acidity of water-powder suspensions and solutions of sintered samples in the direction of decreasing its value depending on the duration of plasma treatment. Also, depending on the duration of treatment, the nature of pH changes when measuring it from a decrease to an increase in this value in both water-powder suspensions and solutions of sintered samples.
