When coming to heat resistance, Basalt is exceptionally suited to block fire. Basalt products resist the open flame. Basalt melts at ca. 1450 C. A fabric made of Basalt, with a […]
2016/06/10· When basalt is exposed to CO2 and water, the carbon precipitates into a white, chalky solid, but in these kinds of conditions, nobody knew how long the process might take. Initial estimates suggested that the process could take between eight to 12 years, but in this case, the conversion began to take place in a matter of months.
