THE processes of making ceramic articles are
largely dependent on the particle size of
the raw materials used. Clays, the primary
material in ceramic compositions, are disintegrated
products of feldspathic rocks and are
said to consist of aggregates of a large number
of fine particles. The l1nest fraction in them,
exhibiting a colloidal phenomena, greatly influence
their physical characteristics such as plasticity,
casting properties, dry strength, etc. |
