Abstract: D36.00002 : Synthesis of boron nitride single crystals under high pressure and impurity/isotope control for their functionalization*
3:36 PM–4:12 PM
Also, controlling of boron and nitrogen isotope ratio (10B,11B and 15N) in hBN and cBN crystals can be now carried out by metatheses reaction under HPHT.
Another issue is to fabricate fine hBN crystals with high quality via conventional route, since hBN is thermodynamically stable at high temperatures and at atmospheric pressure. Ni or Co-base metal base solvents seem useful to obtain high quality hBN crystals, though the yield of the crystals is less than those of high-pressure process.
In this paper, our recent studies on hBN single crystals growth under HP with respect to impurity controls will be reported.
