Most of the experimental results presented in this book would not have been possible to
obtain without high-quality single-crystalline samples. The history of chemical synthesis and …

In this paper, the work function Φ of the NdB 6 (1 0 0) crystal surface have been determined
by both theory and experiment. By the first-principles calculation, the Φ of NdB 6 (1 0 0),(1 1 …

The directionally solidified (DS) LaB 6-VB 2 eutectic composite is successfully prepared by
the optical floating zone technique. The effect of solidification rate on the microstructure …

Abstract LaB 6 (100)-ZrB 2 eutectic composite was directionally solidified by optical floating
melting zone at solidification rate V= 100 mm/h. It was shown that the stable eutectic growth …

The development of a high-power and long-life thermionic ceramic cathode poses
significant challenges, namely the need for high electron emission capacity at low …

A high-quality LaB 6 single crystal with 2–10.24 mm in the diameter was prepared by the
optical floating zone melting technique. The angular deviation from theoretical (100) crystal …

CeB 6-based quaternary rare-earth hexaboride single crystals Ce 1-xy La x Pr y B 6 (x= 0.1–
0.4, y= 0.1–0.4) with Φ 5 mm× 35 mm were grown via the optical floating zone technique …

This paper has studied the crystal structure, growth orientation, crystal quality and thermionic
emission properties of the La 0.9 Sr 0.1 B 6 single crystal prepared by the optical floating …

The efficiency of gyrotrons is significantly affected by the emission inhomogeneity of the
cathode. The current-voltage characteristics (CVCs) of the cathode, which can be used for …

LaB6–HfB2 composites with the different HfB2 contents (10 wt.%, 30 wt.%, 50 wt.%, 70 wt.%,
and 90 wt.%) were densified by spark plasma sintering (SPS). Results showed that the …
