Results and discussion

Boiling point
Boiling pt.:
2 316 °C
Remarks on result:
other: Extrapolated

Any other information on results incl. tables

Since boric oxide has a boiling point of 2200 °C , a boiling point determination is not relevent. An estimate has been extrapolated.

Applicant's summary and conclusion

Conclusions:
Since boric oxide has a boiling point of 2200 °C , a boiling point determination is not relevent. An estimate has been extrapolated: 2316 °C.
Executive summary:

Kirk-Othmer published in 1992 (Kirk-Othmer encyclopedia of chemical technology) that since boric oxide has a boiling point of 2200 °C , a boiling point determination is not relevent. An estimate has been extrapolated: 2316 °C.
