| Hydrostatic press unit | For compressing powder to rod-shape specimen. |
| Mass flow controller | A mass flow controller can be supplied for mixing two different gases for use in the crystal growth. |
| Cold trap | Using the cold trap helps keep the quartz tube
free of contamination due to evaporants. This ensures stable
heating performance during single-crystal growth. The cold trap is particularity effective for highly volatile materials. [Results] Without Cold trap, it is in some cases necessary to the adjust the power of the lamps frequently during the crystal growth because of the gradual contamination of the quartz tube. Cold trap improves the stability of the crystal-growth condition by keeping the quartz tube clean. Cold trap helps to prolong the lifetime of a quartz tube, thus cutting down the running cost. [ Actual example for growing single crystals of Sr2RuO4 ] Before using Cold trap (repeatable usage of a quartz tube: 4 to 5 times) After using Cold trap (repeatable usage of a quartz tube: more than 10 times) [ Actual example for growing single crystals of Sr3Ru2O7 ] Before using Cold trap (repeatable usage of a quartz tube: 2 to 3 times) After using Cold trap (repeatable usage of a quartz tube: 8 to 9 times |
