Fig. 5From: Fabrication of dense albite aggregates by hot pressingApparent density of the samples after hot pressing. Data are also shown in Tables 1, 3. a Relationship between the apparent density and duration of hot pressing. The experimental numbers are annotated on the figure. See Table 1 for the experimental conditions. b Relationship between the apparent density and pressure. The experimental numbers, temperatures and forming methods are annotated on the figureBack to article page
