<p>Tiles have residual moisture content 0.5% and are heated, kept at max. temp., and cooled; heating to 500-700 degrees C., and cooling are at max. speeds determined by thermal stresses. During dehydration period at between 500-700 degrees C and 300 degrees C less than max. firing temp. firing proceeds with elimination of water of hydration at 2-40%/min.</p> |
