• been synthesized from unprocessed colemanite for the first time. The reaction parameters such as time, catalyst type, catalyst amount and temperature were optimized. It was found that the BNNT formation follows the base growth mechanism, which was initiated with a complex of boron nitride (BN) and iron

Keywords: boron nitride nanotube; chemical vapor deposition; colemanite; synthesis; Introduction Colemanite (Ca2B6O11·5H2O) is one of the most important compounds of more than 200 different boron ores. All boron ores include boron oxide (B2O3) at varying percentages in

• materials from this composition cycle, diamond (C) and cubic boron nitride (CBN), possess ultra-high hardness (attributed both to sp3-bonding and relatively short bond lengths) and, for this reason, they are frequently used to manufacture cutting tips. While diamond resides in a cubic lattice structure, CBN

Even though diamond and CBN have similar lattice structures, their surface chemistry is

The deposition rate was monitored by a quartz micro balance and set to approximately 0.5 ML/min. Large-scale ordering of the deposited molecular layers could only be achieved after subsequent annealing
