3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Densityofasolidmaterial true density of the solid material
p, the weight per unit volume, according to the formula (1).
ρ =
(1)
Where.
p --- true density in grams per cubic centimeter (g/cm3);
m --- mass in grams (g);
The V --- volume of solid material, does not include any pores, cubic centimeters (cm3).
Note. The volume of solid material herein does not include the open pore volume.
Principle 4
The sample was milled and sieved to less than 0.063mm. In helium gas analysis, measuring the density of the gas specific gravity meter. Weighing dry
Quality dry samples will be loaded into the analysis chamber. Helium is introduced into the analysis chamber and pressurized to a predetermined value. Then enters the expansion helium expansion
room. Instrument recording pressure balance these two steps. By volume and the quality of gas specific gravity measurement of the sample can be calculated sample true
density.
