Packing Density of Sample

Packing density affects sample contact with the atmosphere. For example, the second step of [Pg.46]

The exothermic peak of the DTA curve of a loosely packed sample was observed at 511.8 °C. Air easily diffused into the sample inside and hence an oxidative atmosphere was sufficiently provided. In contrast, the DTA curve of densely packed samples showed an endothermic peak at 513.5 °C because oxygen was not supplied inside of the sample. [Pg.47]
