| Abstract | The aim of this study was to determine the inorganic filler fractions and sizes of commercially alginates. The inorganic particles volumetric fractions of five alginates - Jeltrate(J), Jeltrate Plus(JP), Jeltrate Chromatic Ortho(JC), Hydrogum(H) and Ezact Krom(E) were accessed by weighing a previously determined mass of each material in water before and after burning samples at 450 degrees C for 3 hours. Unsettled materials were soaked in acetone and chloroform and sputter-coated with gold for SEM evaluation of fillers' morphology and size. The results for the volumetric inorganic particle content were (%): J - 48.33, JP - 48.33, JC - 33.79, H - 37.55 and E - 40.55. The fillers presented a circular appearance with helical form and various perforations. Hydrogum fillers looked like cylindrical, perforated sticks. The mean values for fillers size were (mu m): J - 12.91, JP - 13.67, JC - 13.44, E - 14.59 and H - 9 (diameter), 8.81 (length). The results of this study revealed differences in filler characteristics that could lead to different results when testing mechanical properties. |
