METHOD OF PREPARING A SOLUTION AND APPLICATION OF THIS SOLUTION TO PREPARE FUNCTIONAL OXIDE LAYERS

摘要

In the method of preparation of the Pb-Zr-Ti-containing solutions the lead is added to the Zr- and Ti-containing solution in powdery form. This has the advantage that it takes less time, and that nevertheless a stable solution is obtained. Preferably use is made of Zr- and Ti-butoxides and of lead acetate tri-hydrate. A very suitable solvent is 1-methoxy-2-propanol. The solution can be used for the manufacture of layers on a substrate with a high dielectric constant.
