Ig. Kuzemskaya et al., SYNTHESIS OF SINGLE-PHASE MERCURY CUPRATES USING A PROGRAM CONTROLLEDHIGH-PRESSURE CHAMBER, Journal of low temperature physics, 105(5-6), 1996, pp. 1565-1570
The practically single-phase samples HgBa(2)Ca(2)Cu(3)0(8+delta) HgBa2
Ca3Cu4O10+delta and HgBa2Ca4Cu5O12+delta were synthesized using the pr
ogram-controlled high pressure chamber. The temperature regulation and
maintenance was done automatically. Samples were prepared with differ
ent oxygen content in starting mixture of powder oxides. The as-syntes
ized samples crystallized in P4/mmm space group. X-ray phase analysis
of samples has shown, that the content of main phase was 80-95 %.
