Original Complex Sol Gel Process (CSGP) has been elaborated. In CSGP to the hydroxyalacetoate cations sols a strong complexing agent with high reduction power e.g. ascorbic acid is introduced. Application of CSGP facilitates of synthesis advantage ceramic materials as high temperature superconductors (e.g. YBCO and BSCCO), bioceramics (e.g. hydroxyapatite) and cathodic materials for rechargeable Li-batteries (e.g. LiMn₂O₄, LiCoO₂, LiNi_0.5Co_0.5O₂) in shape of powders as well as coatings on mettalic substrates. A new gelation process CSGP by emulsion technique has been used for preparation of medium sized (diameter below 100 µm) hollow spheres of e.g. Al₂O₃, Fe₂O₃.

The results of these works were presented on MRS Conferences in San Francisco, Boston, San Diego (USA), and in Tokio and Otsu (Japan) in the period of 1990-1997 and described in 30 scientific papers e.g.:
1. Better Ceramics Through Chemistry IV (1990), V (1992), VI (1994)
2. Applied Superconductivity 2, 613 (1995)

Variants of the CSGP process have been protected by the Patents: No. P295195 (June 1992) and No. P300557 (October 1993).
