Production technology of metallocarbonic nanocomposites which sphere of application extends is developed in National Research Technological University “Moscow Institute of Steel and Alloys» (MISIS). With a view of commercialization the developed technology there was a task in view of determination of its marketable cost. The preliminary technical and economic substantiation of the project of detector production of the security-fire alarm system has been spent for an estimation of cash-flows from realization of production on the basis of metallocarbonic nanocomposites. Calculations have shown, what even at use of the developed technology on the scale of 5 % of the domestic market of fire detectors the marketable cost of technology confirmed with the patent — 4,2 million rub., exceeds the considered settlement expenses for its creation in 2–3 times.
