High-toughness white porcelain and preparation method thereof
The invention discloses high-toughness white porcelain and a preparation method thereof, and belongs to the technical field of white porcelain. The high-toughness white porcelain comprises a white porcelain blank and a blank glaze. The white porcelain blank is prepared from the following components in parts by weight: 20 to 30 parts of mullite fiber powder, 40 to 50 parts of SiO2, 20 to 30 parts of Al2O3, 1 to 3 parts of Fe2O3, 0.5 to 1 part of TiO2, 0.5 to 1 part of CaO, 0.5 to 1 part of MgO, 3 to 6 parts of K2O, 3 to 7 parts of Na2O, 8 to 12 parts of ZnO and 7 to 10 parts of B2O3. The blank glaze is prepared from the following components in parts by weight: 45 to 55 parts of potassium feldspar, 16 to 23 parts of calcite, 45 to 65 parts of kaolin, 10 to 15 parts of calcined kaolin, 2 to 3 parts of calcined talc, 7 to 10 parts of ZnO and 5 to 8 parts of BN. The white porcelain has the advantages that the silica sol is added into the material of the blank as a raw material, when the silica sol of the blank is fired, silicon dioxide is combined with mullite fibers, and the toughness effect of the white porcelain blank is improved by utilizing a method of reinforcing the blank by the fibers. Secondly, a multilayer glaze structure is adopted, and zirconium oxide and boron nitride are added into the glaze, and the toughness of the white procelain is improved. Through combination of the two modes, the toughness and hardness of the white porcelain can be greatly improved.
本发明公开了一种高韧白瓷及其制备方法，属于白瓷技术领域，包括白瓷胚体及胚体釉料；所述白瓷胚体的重量份如下：20‑30份莫来石纤维粉末、40‑50份SiO2、20‑30份Al2O3、1‑3份Fe2O3、0.5‑1份TiO2、0.5‑1份CaO、0.5‑1份MgO、3‑6份K2O、3‑7份Na2O、8‑12份ZnO、7‑10份B2O3；所述胚体釉料的重量组分如下：45‑55份钾长石、16‑23份方解石、45‑65份高岭土、10‑15份烧高岭、2‑3份烧滑石、7‑10份ZnO、5‑8份BN；本发明的优点在于胚体的材料中加入硅溶胶作为原料，胚体的硅溶胶在烧制时，二氧化硅与莫来石纤维结合，利用纤维增强胚体的方法，提升了白瓷胚体的强韧效果，其次采用多层结构釉料结构，在釉料中加入氧化锆及氮化硼，提高白瓷的韧性，通过两种方式的结合，能够大幅度提高白瓷的韧性及硬度。
