Abstract: TiB2/B4C composite ceramic powder was synthesized in situ through co-precipitation mainly with TiCl4 solution and B4C powder as raw materials. TEM was used to investigate the effects of the pH value of the solution and titration rate of NH4 (OH) on Ti(OH)4-clad B4C, while XRD was used to the effect of synthesizing temperature on the phases of the powder. And the thermodynamics of synthesis of TiB2/B4C composite powder was analyzed. The results indicated that when the pH value of the solution is 5 with a titration rate of 2 ml/min the Ti(OH)4-clad B4C is best, and the TiB2/B4C composite powder is available to be synthesized if the synthesizing temperature is higher than 1350°C.
