Description
Technical field
The present invention relates to a kind of Novel bone porcelain base substrate, further, relate to a kind of fluxing agent system of Bone China base substrate, belong to the domestic ceramics field.
Background technology
Bone China is a high-grade porcelain kind that results from Britain, apart from modern existing more than 300 year history.Bone China is take the bone ash of animal or synthetic bone meal (content is more than 36% in the blank), clay, feldspar and quartzy as basic raw material, passes through high temperature biscuiting and low temperature sinter and fires a kind of porcelain that forms for twice.
Bone China is penetrating because of its porcelain exquisiteness, type elegance attractive in appearance, the moist light of glaze, the colourful characteristics of flower face, having achieved its pure white quality and luxurious moulding, had concurrently and use and artistic dual value, is the treasure of imperial palace special product and noble's collection in history, be power and status symbol, be known as " king of porcelain ".Bone China becomes world's ceramic treasures gradually behind the hand through generation code name craftsman, be at present unique high-grade porcelain kind of generally acknowledging in the world.
The superior outward appearance that the Bone China whiteness is high, transparency good, porcelain is soft, gloss is soft is to be determined by its unique microstructure.China porcelain body microstructure is mainly by β-Ca
3(PO
4)
2, lime feldspar, cristobalite, mullite and glassy phase consist of.Glassy phase can reach about 40% in the bone china, and the specific refractory power difference between each phase is little, and (glassy phase is 1.56, and lime feldspar is 1.58, tricalcium phosphate 1.59-1.62), thereby scattering of light is less, and transparency is good and bright soft, decorative effect is good, and sound is melodious especially.
But the just existence of a large amount of glassy phases in the Bone China porcelain body causes its fragility larger, and thermostability is relatively poor, and firing range is narrow, and is wayward.Poor heat stability particularly, only be that a heat exchange of 140 ℃ → 20 ℃ water does not burst (national standard), cause the Bone China product can not enter four-star, five-star hotel and catering industry, mostly only use with porcelain as gift and furnishings, seriously limited its Application Areas.
For this reason, a lot of scientific and technical personnel have carried out a large amount of work, as add the measures such as other material is toughness reinforcing, enhancing, all are not significantly improved, and the industrialization achievement is not also arranged.
Goal of the invention and content
The object of the invention is to solve since the Bone China birth, the intensity that exists is low, the inherent defect of poor heat stability, and provide a kind of novel synthetic flux, this synthetic flux, the on the one hand fully liquid phase sintering of Substitute Feldspar flux realization Bone China base substrate, on the other hand, in the porcelain body process of cooling, this flux is whole crystallization almost, change superfine small-crystalline into, like this under the prerequisite that does not change the Bone China excellent appearance, almost all change the glassy phase in the conventional bone porcelain porcelain body into superfine small-crystalline, significantly promote physicochemical property, especially physical strength and the thermostability of conventional bone porcelain, thereby it is low to have solved the intensity that has existed since Bone China is born, the inherent defect of poor heat stability.
