Combustion synthesis technology, also known as self-propagating high-temperature synthesis technology, is a special combustion synthesis reaction, which uses external energy to induce chemical reactions locally in the exothermic reaction system, and forms a self-sustaining frontier combustion wave. At this time, the chemical reaction continues to advance under the self-exothermic heat of the precursor material, forming a combustion wave that spreads at a certain speed. With the advancement of the combustion wave, the original mixed materials are gradually converted into products, and when the combustion wave spreads to the entire sample, the synthesis of the required materials is completed.
20 years of advanced technology accumulation
SDZK Advanced Ceramic Technology Corporation is mainly engaged in the preparation of new technologies and combustion synthesis theory of "structure-function integrated advanced ceramic materials", as well as the industrial application research of "new ceramic/special refractory metal materials".
For more than 20 years, SDZK has been committed to the theoretical and technological research of combustion synthesis of high-quality ceramic powder materials. It has successively made all-round technological breakthroughs in "large-scale combustion synthesis equipment, intelligent control of combustion reaction process, and stabilization of process products"; among them, large-scale equipment, ultra-high temperature combustion synthesis of thermodynamically stable α-Si3N4 at low temperature, and carbonization combustion synthesis The three aspects of ceramics/graphene are in the leading position in the world.
SDZK's goal is to "lead the development of advanced ceramics industry with combustion synthesis technology". In terms of the industrialization of combustion synthesis, SDZK has successfully developed and successfully synthesized high-quality silicon nitride powder by combustion in a large-scale low-pressure reactor for the first time in the world.
The self-developed reactor used is the largest high-pressure combustion synthesis equipment at present. Academician Alymov, director of the Institute of Macrodynamics of Materials and Structures of the Russian Academy of Sciences, highly praised and paid attention to this achievement. Since 2014, Alymov has visited and cooperated with his assistant Dr. Smirnov many times. During the EPNM International Conference in 2016, I conducted many in-depth discussions on combustion synthesis technology with the staff of the Institute of Physics and Chemistry.
It can be said that SDZK is at the international leading level in the engineering and scale of combustion synthetic ceramic powder materials.
SDZK has built a high-quality silicon nitride powder production line with an annual output of 200 tons.
