Research on chemical exchange process of boron isotope separation

The chemical exchange process of boron isotope separation was studied in order to enrich rare stable isotope 10B. Specially, the relations among the pyrolysis temperature, the number of theoretical plates, the exchange reaction time, the enrichment factor and the abundance of 10B were investigated. The conclusion was obtained by experiment that the abundance of 10B could reach to 36.3% with the pyrolysis temperature of 160, and the exchange reaction time °C to 192 hours. It will lay better foundation for the industrial scale production in the next step.
