Resumo

The effect of phenol formaldehyde resin (PFR) on the preparation of TiB₂ powders by carbothermal synthesis at temperatures (T) of up to 1670 K has been studied by simultaneous thermal analysis. Unlike in the case of dynamic heating, under isothermal conditions (1570 K, 3 h) the addition of PFR increases the product yield by 13%. The formation of carbon black as a result of PFR thermolysis is favorable for the formation of titanium carbide, from which TiB₂ is synthesized.
