Analysis of Compressibility Origins in Monolithic Ceramic Suspensions Using X-Ray Imaging Techniques
In the past two decades, significant advances have been made in the synthesis of new types of nonclay ceramic powders (e.g., oxides, borides, carbides, nitrides), which today have an unprecedented degree of control over particle size, shape, and chemistry . A particular trend has been the increased production of smaller and smaller (typically submicron) powders in order to (i) reduce sintering temperatures, (ii) strengthen ceramics by decreasing the size of Griffith’s flaws, and (iii) allow the processing of composites with individual phases distributed at smaller and smaller scales of mixing.
