High-field27Al mas NMR studies of the ... - SpringerLink

Flash calcination was used to dehydroxylate kaolinite and produced calcines kinetically frozen at various stages during metakaolinite formation. High speed magic-angle spinning 27 Al NMR, in magnetic fields of 14.1 and 11.8 T, enabled new features to be observed in the metakaolinite spectrum. The dependence on magnetic field of simulated and experimental spectra is discussed, and the effects .

A procedure for preparing clay or a clay body by hand: the lump of clay is repeatedly thrown down on a work bench; between each operation the lump is turned and sometimes cut through and rejoined in a different orientation. The object is to disperse the water more uniformly, to remove air.

How Temperature Changes Clay

Before the glass-making oxides begin to melt, the clay particles will already stick to each other. Beginning at about 1650 F (900 C), the clay particles begin to fuse. This cementing process is called sintering. After the pottery has sintered, it is no longer truly clay but has become a ceramic material.
