1Percentages retained on Tyler sieves are derived from average production figures and do not represent specifications. The lower the sieve number, the more coarse the grog. |
Clay bodies with mullite added show a uniform thermal expansion and are resistant to deformation. Their strength is due to the interlocking of the long crystal structure of Mullite.
