Following the classification described in Table 8.1, other precursor materials, such as metal nitrates or metal acetates combined with complexing and polymerizing agents such as citric acid, ethanolamines, tartaric add and ethyleneglycol, are frequently used in more recently reported studies. 

A similar classification has been adopted in B.S. 1344 (Part 2) but the time of exposure to the 10% citric acid is 20 min and the temperature is 20 °C. BS 1344 Pt 3 tests resistance to H2SO4 other parts test resistance to hot acids, alkalis and detergents. 

Deviations from the above classification are also reported in the literature [93,94]. Synthesis of filamentous carbon from Cr3C2 was studied under hydrothermal condition at 100-200 MPa and 350-800°C. The formation of spherical and filamentous carbon was observed in the presence of organic compounds (ascorbic acid, malonic acid, glycolic acid, oxalic acid, citric acid, and stearic acid) at...
