SYNTHETIC CERAMIC FOAM COMPOSITE MATERIALS

SYNTHETIC CERAMIC FOAM COMPOSITE MATERIALS:

- Development, fabrication and research of ceramic foam composite materials and nanostructures on their basis.

Main results: 

- Methods for producing modified ceramic foam material (HIPE К ) have been developed. This rigid, nonflammable material possessing heat insulating properties and resistant to humidity, atmospheric effects, vibration, and biodeterioration is on par with the best world analogues. It is convenient for use in petrochemistry, civil and industrial engineering, power systems, and other branches. HIPE К does not burn, does not collapse in the flame on open air, it is ecologically safe, can be easily processed mechanically and has the density from 300-400 kg/ m3 (for casting in rigid cavities from 125 kg/ м 3 ); thermal conductivity - from 0,04 W/mK at 25±5 о С ; breaking strength up to 500 k Ра / с m2 С ).
- On the basis of HIPE К ceramic foam, some hi-tech products have been developed:
- heat insulating materials with working temperature up to 2500° С ;
- heat resistant (1000 – 2500 о С ) filters with adjustable size of pores for refinement of metals and alloys, which cost 2 times less than the best analogues;
- nanostructured catalysts of pyrolysis processes for raw propane-butane mixture (I) and for cleaning of exhaust gases of internal combustion engines (II).
- It is shown that process I in a pulse mode in the conditions of gas flow at 500-775 о С and contact time of 2-14 seconds occurs practically without formation of coke with the yield of ethylene up to 60 percent and propylene of 30 percent by weight. Research work is underway to develop sorbents and catalysts for deactivation of dangerous viruses and microbes.
