Refractories Aims and scope

Conclusions

Tips made of MgO can operate in argon at 2400°C for up to 5 h.

Tips of ZrO2 are suitable for measuring temperatures up to 2400°C for several minutes and for longer periods up to 1900°C both in vacuum and in atmospheres of nitrogen and argon.

Long tips should be fitted to graphite rods.
