When chromium, or chromium sesquioxide, is heated with boron in an electric furnace, borides are formed. If the operation is carried out in a carbon crucible, the product always contains free carbon which cannot be completely separated. By reducing the sesquioxide by heating with boron in magnesia crucibles in an electric furnace, du Jassonneix obtained a series of alloys containing 5 to 17 per cent, of combined boron, and succeeded in isolating two definite borides of composition CrB and CrgBg. 

After complete conversion to U02(B02)2 is achieved, the uranyl salt is freed from B2O3 by dissolving the excess sesquioxide in absolute methanol. Reasonable care should be taken to minimize access of moisture to the metaborate during the purification step, but completely anhydrous conditions are not required. A sample of IJO2B2O4 prepared as described above gave the following analytical results uranium found 66.80%, theoretical 66.93%, and boron found 6.02%, theoretical 6.08%.
