The densities ([rho]) were measured by the automatic oscillating U-tube
densimeter (DMA 4500, Anton Paar, Austria, precision of 1.0 x [10.sup.-5] g x [cm.sup.-3]) with standard uncertainty of 0.5 mg x [cm.sup.-3] at 0.681 level of confidence [7].
Density and conductivity are measured using a
densimeter and conductimeter, respectively.
The soil parameters analyzed were clay (
densimeter, NaOH solution), pH and pH in buffer solution (glass electrode), total phosphorus (P) (light absorption at 660 nm, Mehlich-1), organic matter (OM) (645 nm, sulphochromic solution), potassium (K) (atomic absorption, Mehlich-1), aluminum (Al), calcium (Ca) and magnesium (Mg) (atomic absorption, KCl).
The bulk density of the sintered samples was measured based on Archimedes' principle, using the water immersion method with a standard Mettler Toledo Balance AG204
densimeter. Polished samples were used to determine Vickers's hardness and fracture toughness ([K.sub.IC]) using Vickers's indentation method.
Soil texture was determined using a Bouyoucos
densimeter after shaking the soil vigorously with NaOH 1M as dispersant.
Density is measured with standard
densimeter with the precision of 0.001 g/[cm.sup.3].
Another instrument that is popularly used by Islamic pawnbroking institutions is
densimeter such as MD-200S/GK300.
Density and Speed of sound were measured by ANTON PAAR
densimeter (DSA 5000) to an accuracy of [+ or -] 0.000005 g/[cm.sup.-3] and [+ or -] 0.5 m/s, respectively.
