摘要
The preparation of a stable sol-gel solution precursor of a ceramic oxide comprises: (A) preparing a sol-gel solution from molecular precursors of lead, titanium, zirconium and a metal lanthanide with a diol solvent and possibly an aliphatic mono-alcohol; (B) resting the solution for sufficient time to obtain an essentially constant viscosity; and (C) diluting the solution to a determined level with an identical diol solvent or a miscible solvent. Independent claims are also included for: (A) the sol-gel solution obtained from this method of preparation; (B) the preparation of a ceramic material using the sol-gel solution; and (C) the ceramic oxide material produced.
