The invention discloses a method for producing a
microcrystalline glass-ceramics composite board with novel
microcrystalline phase, which is characterized in that the composite board takes
diopside-containing
pyroxene as
microcrystalline phase and the production method thereof comprises the steps as follows: firstly, microcrystalline glass granules are prepared; according to the weight percentage, the microcrystalline glass consist of 50-65% of SiO2, 5-25% of Al2O3, 5-20% OF CaO, 2-10% of MgO, 1-8% of K2O+NaO, 0-1% of Li2O, 0-8% of BaO, 0-8% of B2O3 and the balance of nucleating agent,
clarifier and corant with the content
ranging from 0 to 20%; secondly, a
ceramic palette board is prepared; according to the weight percentage, the
ceramic palette board comprises 66-75% of SiO2, 13-23% of Al2O3, 0.3-3% of CaO+MgO, 3-8% of K2O+Na2O and the balance of 0-2% of auxiliary
raw material; finally, the raw materials are distributed, sintered and post-processed, thus gaining the finished product of the microcrystalline glass-ceramics composite board. The method has the advantages of low production cost, high product quality, good appearance effect, and the like.
