♦ The untamped density of aluminium oxide is given by the formula m2-m0/m1-m0
where
—m0 is the mass, in grams of the empty cylindrical container
—m1 is the mass, in grams of the cylindrical container full of distilled water
—m2 is the mass, in grams of the cylindrical container full of aluminium oxide
♦ If the cylindrical container used has a capacity of exactly 200 mL, the formula for the calculation of untamped density becomes m2-m0/200
♦ All LABULK cylindrical containers are calibrated on volume.
♦ It will usually be more convenient to use one particular cylindrical container of capacity approximately 200 mL and determine the value of (m1-m0) to be used in all determinations.
