In this work, magnesium borate (Mg2B2O5) and aluminum (Al18B4O33) whiskers with a high aspect ratio were successfully synthesized using molten salt method. The phase transformation morphology involution of the studied by XRD, IR-FT, TG-DSC, SEM-EDS different boron/metal ratios reaction temperatures. results show rich boron environment appropriate temperature to be crucial factors respect compos...
