1. a preparation method for high strength electroceramice, is characterized in that, concrete technology step is:

  • (1) bauxitic clay, mullite, highly plastic clay and feldspar will be calcined prepare burden as raw material by following mass fraction;

    Calcining bauxitic clay;

    20 ~ 30 partsMullite;

    20 ~ 30 partsHighly plastic clay;

    20 ~ 35 partsFeldspar;

    15 ~ 25 parts(2), after being mixed by raw material described in step (1), add water, ball milling, obtains slurry;

    (3) slurry is sieved, deironing, after filter-press dehydration mud cake;

    (4) after mud cake slightly being practiced old more than 24 hours, then to wet base with the vacuum deairing machine electroceramics extruded as desired size, after repaired biscuit and drying green compact;

    (5) be placed in by green compact in drawer type or tunnel-type kiln, burn till at 1260 DEG C ~ 1330 DEG C, firing time is 24 hours ~ 48 hours;

    Then cool, kiln discharge obtains high strength electroceramice.
