layers of high density pyrolitic graphite and a layer of silicon carbide in between (TRISO), and the external part of the pebble is made of high purity graphite. The TRISO micro-spheres have a diameter of 0.9 mm [16-19]. In the neutronic calculations carried out in

Abrasives - HORIBA

The laser diffraction technique is capable of covering almost all of the abrasive size ranges and is quicker and easier than either sieves or sedimentation. For this reason laser diffraction is becoming more popular as a technique. Results from the LA-960 laser diffraction analyzer for diamond and silicon carbide abrasives are shown below.
