Electroceramic added with compound seed crystal and preparation method of electroceramic
The invention discloses an electroceramic added with compound seed crystal and a preparation method of the electroceramic. The electroceramic is prepared from such raw materials in percentage by weight as 10-20% of SiO2, 10-25% of Al2O3, 10-20% of Fe2O3, 1-5% of TiO2, 2-10% of CaO, 0-3% of MgO, 5-15% of K2O, 3-8% of Na2O and 2-20% of compound seed crystal. As the compound seed crystal (CaB2O4 seed crystal and CaB4O7 seed crystal) is added, the sintering process of the electroceramic can be accelerated, the density of the electroceramic can be increased and the breaking strength of the electroceramic can be remarkably enhanced; besides, due to the addition of the compound seed crystal, the crystallization of the mullite phase also can be effectively promoted, and therefore, the mechanical strength of the electroceramic can be remarkably improved. The preparation raw materials of the electroceramic are simple and easily available, and the process is stable and mature, and satisfies the practical and industrial conditions.
