Production of Advanced Materials by Self-Propagating High-Temperature Synthesis

A joint monograph-„Production of Advanced Materials by Methods of Self-Propagating High-Temperature Synthesis“ by Director of the Institute,Academician of Georgia NAS D.t.s., Professor Giorgi Tavadze and University of Berkeley (USA) Prof. Alexander S. Shteinberg, Doctor of Physical and Mathematical Sciences was published in the Chinese language in December 2016.


The book has been translated into Chinese by Professor Shu Iuantszem.

 

The following issues are discussed in the book:

 

  • Production of elemental boron and boron-containing refractory compounds by SHS technology with metallothermic reduction. Thermodynamic analysis is performed to determine parameters of anticipated chemical reactions that served as a basis for the production of crystalline boron, boron carbide and boron nitride from potassium tetraborptoride and boron oxides;
  • Production of tungsten and zirconium borides-based hard alloys by SHS technology and study of the properties of produced materials. Special attention is paid to the feasibility of titanium diboride production with changing gravimetric composition of powders in the primary burden;
  • With few exceptions, the SHS processes proceed with gas evolution. Usually gas evolution during combustion helps “self-purification” of SHS reaction components which results in producing a purer product compared to primary product. It is worth noting that often gas evolution impedes the synthesis and calls for filtration processes.
  • Determining macrokinetic parameters of filtration has enabled researchers to regulate SHS methods, namely, to carry out compacting SHS and synthesized product in a single cycle and band together SHS-produced materials. This became possible upon the resolution of process issues - reagent mass ratio, geometrical parameters of the item design, tensions originating in the item design, and other engineering problems.
    The book is intended for SHS and materials science specialists.
