“…Several groups reported the rocksalt crystal structure for YN with lattice constants between 4.8 and 4.9Å [12][13][14][15]. No other crystal structure has been experimentally reported for YN, but a recent first principle calculation compared the wurtzite and bcc structures to the rocksalt structure (the latter was the most stable) [16].…”

“…In the 1950s, a group produced YN powder by first converting yttrium metal to YH 2 by reacting with hydrogen at 550 1C in a quartz tube, then heating this gas to 900 1C in the presence of nitrogen [12]. Later in the 1960s, YN powders were obtained by reacting yttrium metal with nitrogen at 1400 1C [13] and arc-melting under 0.3 MPa nitrogen [14].…”

“…[11][12][13] Recently, the phase relationships in the Si 3 N 4 -YN 14 and Si 3 N 4 -SiO 2 -RE 2 O 3 -REN (RE‫ס‬Y, La) 15 systems were investigated without using the nitride starting material. In both studies, the phase relationships were deduced from samples synthesized mainly by the carbothermal reduction-nitridation of RE 2 O 3 -SiO 2 , 14,15 RE 2 O 3 -Si, 14 or RE 2 O 3 -Si 3 N 4 15 mixtures with various RE/Si ratios.…”

Lutetium nitride (LuN), an end member of a new quaternary system Si 3 N 4 -SiO 2 -Lu 2 O 3 -LuN, was synthesized by direct nitridation of a lutetium metal. The nitridation extent of the lutetium ingot (10 × 5 × 2 mm) reached about 97% by heating at 1600°C for 8 h with an applied N 2 pressure of 0.92 MPa; the initial shape of the bulk metal was maintained in the course of nitridation. The resulting nitrided lutetium possessed a moderately low oxygen content (∼0.7 wt%), which enables the preparation of uncharacterized high nitrogen-containing phases in the Lu-Si-O-N system.
