Jul 28, 2008· The melting point of KOH is 406 °C, ΔG for this reaction at 298 °K is expected to be more negative than that of reaction and hence one can expect that the former has slightly more decomposition effect on zircon than NaOH. Therefore, when the mixed alkalis used, the competition of KOH is longer than that of NaOH, which mean that the molar percent of KOH may decrease than that .

RECOVERY OF ZIRCONIA FROM ZIRCON SANDS The use of zirconia in many fields has grown enormously. The major and cheapest source of zirconia is zircon sand. Despite this, the decomposition of zircon is not easy to achieve due to its stability. Considering the structure of zircon, which is extensively discussed in the literature [3.
Science as you've never seen it before. Illustrated with the latest CGI technology, this children's encyclopedia brings a groundbreaking new visual approach to the world of science.
A novel method was proposed for preparing oxychloride octahydrate by the two – step decomposition of zircon sand concentrate in sodium hydroxide system. The effect of decomposition temperature and NaOH – to – zircon mass ratio of each stage on the decomposition of zircon sand was investigated. The macrokinetics of the two – step decomposition process was also examined.
