Chemical vapour growth of HfP whiskers and their properties

Whiskers and ribbon-like single crystals of β-HfP (hexagonal) have been prepared from HfCl4 + PCl3 + H2 + Ar gas mixtures at 1100-1200°C using a metal impurity-activated chemical vapour deposition process. The growth conditions, morphology and chemical properties were examined. The 3.5-6.5 mm (average 4 mm) long HfP whiskers were obtained at 1200°C using Si + Pt or Si + Pd mixed impurities. The HfP whiskers were very stable against oxidation up to 3 h exposure at 1000°C and for 80 min immersion in concentrated HCl solution at 50°C.
