ZrB 2 based composites were prepared by a novel reactive melt infiltration process. The porous boron bars were used as preforms and infiltrated by the low melting Zr 2 Cu intermetallic compound. Thermodynamics calculations revealed that B could react with liquid Zr 2 Cu to form ZrB 2 as low as 1100°C. Composites were prepared by heating the two materials to 1200°C for...
