Preserved Fulltext
The joint reduction of zirconium oxide and sodium carbonate with the formation of zirconium carbide was studied. It was shown that with magnesium thermomes ZrO2 and Na2CO3, the reduction of ZrO2 occurs in the range of 600‒620 °C, and Na2CO3 ― in the range of 590‒610 °C. Thermodynamic calculations and the results of X-ray diffraction analysis allowed us to judge the transformations occurring in the synthesis process and the resulting reaction products. It has been established that the use of
