Peculiarities of γ-AlO Crystallization on the Surface of h-BN Particles.

The main goal of the present work was to synthesize a composite consisting of h-BN particles coated with a γ-AlO nanolayer. A method was proposed for applying nanocrystalline γ-AlO to h-BN particles using a sol-gel technique, which ensures the chemical homogeneity of the composite at the nano level. It has been determined that during crystallization on the h-BN surface, the proportion of spinel in alumina decreases from 40 wt.

Influence of Graphene Sheets on Compaction and Sintering Properties of Nano-Zirconia Ceramics.

The use of a nanostructured graphene-zirconia composite will allow the development of new materials with improved performance properties and a high functionality. This work covers a stepwise study related to the creation of a nanostructured composite based on ZrO and graphene. A composite was prepared using two suspensions: nano-zirconia obtained by sol-gel synthesis and oxygen-free graphene obtained sonochemically.

Cryochemical synthesis of ultrasmall, highly crystalline, nanostructured metal oxides and salts.

In the present investigation, the cryochemical approach was used for the improved synthesis of nanocrystalline metal oxides (e.g., NiO, FeO, CeO) and NaNO salt.

Wet-chemistry processing of powdery raw material for high-tech ceramics.

The purpose of this study was to develop wet-chemistry approaches for the synthesis of ultradispersed and mesoporous metal oxide powders and powdery composites intended for usage in the production of ceramic materials with desired properties. The focus is on the development of template synthesis of mesoporous metal silicates as well as obtaining nano- and subnanopowders by a modified sol-gel technique and template methods. Families of mesoporous (2 to 300 nm) metal silicates and nano-oxides and subnanopowders (4 to 300 nm) were synthesized by the template method and modified sol-gel technique, respectively.
