A method for producing a biocompatible material of the formula NaKNbO, 0&#x2266;x&#x2266;0.8, 0.2&#x2266;y&#x2266;1, x+y=1 includes the steps of a) providing a Na-precursor and a K-precursor for NaKNbO, b) mixing the precursors in solution wherein said precursors first react to form a sol and thereafter a gel, c) heat treating the gel to obtain an oxide of the material NaKNbO, 0&#x2266;x&#x2266;0.8, 0.2&#x2266;y&#x2266;1, x+y=1. The material can be produced as a film, and the material or film can be provided on the exterior surface of a medical implant that will come into contact with body tissue and/or body fluids upon implantation thereof.

Method for producing a piezoelectric film

Synthesis of sodium potassium niobate by sol-gel

A novel solution route has been developed that after heat-treatment to 500-600&#xb0; C. under inert atmosphere, yields highly porous composites of nano-sized metal (Ni) particle inclusions in ceramics (AlO). Metal loadings could be made from &#x3c;1% to &#x3e;95% Ni. The metal inclusion sizes in the Ni&#x2014;AlOsystem with the 10 atom % Ni sample were 4-7 nm, while for the 75 atom % Ni sample they were 5-8 nm. It was shown that the 10 atom % Ni sample could be used as a catalyst for the conversion of COand CHin the temperature range 550-700&#xb0; C., while higher temperatures led to growth of the Ni particles and carbon poisoning over time. The solution routes could also be deposited as thin dense films containing &#x3c;10 nm Ni particles. Such films with high Ni-particle loadings deposited on aluminium substrates have shown very good solar heat absorber proficiency and provide good substrates for carbon tube growth.
