Impurity levels in the solution (MCR) is one of the several factors that govern the tensile strength of carbon fibers, other factors being precursor fiber properties, strains in stabilization and
carbonization, time and temperature of stabilization and
carbonization.
Several methods, such as chemical vapor deposition [4],
carbonization of polymer [5-7] and pressure
carbonization [8, 9], have been widely used to synthesize carbon materials.
The results indicated that adsorption capacity of the adsorbent was influenced by solution pH, initial metal ion concentration, contact time, adsorbent dosage, particle sizes,
carbonization temperature and solution temperatures.
Table 5 shows the weight and volume changes of MG during the process of
carbonization and HTP.
According to the study by Mo and Panesar [14], after 56 days of
carbonization, the strength of the 40% magnesium oxide test piece is close to that of the 20% magnesium oxide test piece so that three different proportions (mass ratio) are used; MgO in the curing agent doping are 15%, 25%, and 35%.
During the hydrothermal
carbonization, we investigated the effects of the reaction temperature, the reaction time, and the mass ratio of S.
The variables to be measured were the depth and width of the incisions, the
carbonization area, and the necrotic area.
The
carbonization was performed in a tubular electrical furnace.
Due to the availability, cheap cost, and ability to become highly porous after
carbonization, different kinds of biomass feedstock have been used as precursors for carbon.
This was then followed by heating at a rate of 5[degrees]C per minute up to 600[degrees]C in a nitrogen environment to bring about
carbonization of the polymer fibres and calcination of Ti[O.sub.2] particles.
