摘要：

Self-propagated high-temperature synthesis (SHS) of TiB2 and ZrB2 is carried out in a steel reactor under Ar. The SHS is initiated by a current pulse of 60 A and 40 V. It is shown that the interparticle contacts play a significant role in the successful proceeding of the synthesis reactions. The products obtained have similar morphology. X-ray data show the presence of well-crystallized phases of TiB2 and ZrB2. Chemical analyses indicate a high boron content in the products. The properties of TiB2 powders synthesized from the same initial titanium and boron reagents by both SHS and mechanochemical synthesis are compared.
