“…The first is the simplicity and safety of its production, as described in [17]. It should be noted that the traditional "explosive" methods of producing acetylene black [13][14][15] require compression of acetylene to pressures exceeding 10 bar. An uncontrolled explosion may occur during the production, so, complex and expensive measures are required to ensure the industrial safety.…”

The production method of nanoscale detonation carbon (NDC) has recently been developed at Lavrentyev Institute of Hydrodynamics SB RAS. This method uses the reaction of acetylene with oxygen conducted in the detonation mode in fuel-rich acetylene–oxygen mixtures. The morphology and structural features of the NDC particles can be varied by changing the concentration of oxygen in the gaseous mixtures. The particles of NDC can serve as reinforcements in metal matrix composites and additives imparting electrical conductivity to polymer matrix composites. Before NDC can be considered for industrial applications, it is necessary to address the related biological safety concerns. The present work was aimed at determining the cytotoxicity of NDC. The NDC powders with two morphologies (obtained using different acetylene/oxygen ratios) were tested on HEK293A human cells. The NDC powder was added to the culture medium in concentrations ranging from 10 ng/mL to 400 μg/mL. The cell viability was determined by a colorimetric EZ4U test and a real-time cell analyzer xCELLigence. None of the NDC samples showed a cytotoxic effect. The results of this study allow us to recommend NDC as a safe and useful product for the development of advanced carbon-based and composite materials.

“…The majority of industrial carbon black grades are produced by decomposition of hydrocarbons, e.g., using the furnace black process. Another possibility to produce carbon black is to use the detonation decomposition of acetylene [13][14][15][16]. This method allows obtaining high-quality carbon black, also known as acetylene black.…”
