Refractories Aims and scope

Conclusions

The writers developed optimal compositions and the technology for corundum tubes of high thermal strength for furnaces for growing monocrystals. The durability of the fired tubes was 58–104 days and that of unfired tubes 51–82 days.

The technology is based on the use of high-fired granular corundum filler, not more than 40% fine-ground components, and 20% addedγ- Al2O3 for fired tubes and 5% added H3PO4 for unfired tubes.
