Abstract
The invention relates to a ceramic fusion cake with high aluminum content, in particular to a flux material used for sintering a ceramic glaze with higher temperature. The fusion cake comprises the following components in percent by weight: 65-75 percent of SiO2, 10-14 percent of Al2O3, 6-12 percent of B2O3, 2-6 percent of CaO, 2-6 percent of Na2O, 2-5 percent of ZnO, 2-5 percent of MgO and 5-10 percent of ZrO2, wherein the consumption range of the fusion cake in the ceramic glaze is 40-95 percent. The ceramic fusion cake has the characteristics of higher aluminium content (Al2O3: 10-14 percent), higher melting temperature, crawling temperature of 1000-1100 DEG C, sintering temperature of 1100-1150 DEG C and initial-melting temperature of 1180-1220 DEG C, can be used as a main raw material of the ceramic glaze, has the consumption range of 40-95 percent in the ceramic glaze, can be used for glazing, can enable the ceramic glaze to reduce pinholes and improve gloss, and has smooth glaze, sintering temperature widening and stable production.
Description
One, technical field
The present invention relates to a kind of high-aluminum fusion cake for high initial-melting temperature ceramic glaze, it is pottery frit with high aluminium content, be that the higher pottery of a kind of firing temperature is joined the used flux material of glaze, specifically relate to have high aluminium content, high initial melting temperature, be applicable to that the higher pottery of firing temperature joins the glaze once-firing, improve glaze quality.
Two, background technology
Frit is with raw material fusion in advance or becomes vitreum, is that pottery is joined glaze a kind of flux raw material commonly used.When flux is made in fusion in advance, can from the glaze raw material, get rid of most of gas, thereby can reduce the bubble of Ceramic glaze, the generation of pin hole.The ceramic meaning that this is higher to firing temperatures such as domestic ceramics, snitaryware, firing period is short is especially great.
Frit is widely used in the fine pottery that burns till fast at present and joins in the glaze.Because its low initial melting temperature and big firing range make frit join at the architectural pottery goods that burn till fast and have the effect of not replacing in the glaze.And the higher porcelain of firing temperature is joined glaze based on raw material always, even useful frit is joined the situation of glaze, its consumption also very little (the frit consumption in joining glaze＜30%.)。
Relevant by retrieval document: Chinese patent CN1401603 discloses a kind of strange ice stone nanometer frit and nanometer domestic ceramics, is the application of nanotechnology in the domestic ceramics field.Method is that nano raw material is added in the frit batching, makes frit have the nanometer effect.
Chinese patent CN1472155 lead-free fritting enamel belongs to a kind of pottery fritted glaze technical field.Its raw material of being made up of following weight proportion is founded and is formed: quartzy 15～30%, feldspar 30～50%, borax 7～15%, boric acid 5～15%, barium carbonate 3～6%, Stalactitum 6～12%, zinc oxide 3～6%, Strontium carbonate powder 2～5%, Quilonum Retard 2～4%, ripe talcum 2～4%, aluminium hydroxide 2～8%.Realize that plumbous molten output is zero, can fully satisfy people needs healthy, high-quality pottery.
Chinese patent CN1594165 the present invention relates to a kind of china sanitary ware fritted glaze, it is equipped with raw material by frit and forms, frit accounts for 80 at the per-cent of joining glaze---and 95%, the raw material kind is less than 3 kinds, and raw material content is less than 20%, china sanitary ware fritted glaze provided by the invention, make the sanitary ceramic ware materials realize specialized, stdn, improve glaze quality, improve glaze brightness, reduce pin hole, widen firing temperature, the overall quality of china sanitary ware product is improved.
By retrieving relevant document, do not see existing identical with the technology contents of the present invention or akin reported in literature of patent.
Three, summary of the invention
The objective of the invention is at the deficiencies in the prior art, improve the glaze quality of porcelain, enlarge the firing range of porcelain, it is convenient more to make porcelain join glaze, realizes finally that porcelain is joined the specialization of glaze and a kind of--------high-aluminum fusion cake for high initial-melting temperature ceramic glaze of providing.
Task of the present invention is finished like this:
The compositing range of its frit is (by weight percentage): SiO
265～75%, Al
2O
310～14%, B
2O
36～12%, CaO 2～6%, Na
2O 2～6%, ZnO 2～5%, MgO 2～5%, ZrO
25～10%; Its frit joins at porcelain that amount ranges is 40～95% in the glaze.
Characteristics of the present invention:
(1) has high aluminum content (Al in the composition
2O
3: 10～14%);
(2) frit itself has high initial melting temperature (1180～1220 ℃);
(3) can be used as porcelain and join the main raw material of glaze (joining glaze consumption＞30%).
Characteristic of the present invention is:
1, the higher (Al of the aluminum content of product
2O
3: 10～14%), the aluminum content of frit generally is no more than 8% (about 0.2 mol equivalent) at present.
2, product has higher melt temperature.The frit produced of the present invention after measured, the glaze temperature that contracts is 1000～1100 ℃; Sintering temperature is 1100～1150 ℃; It is 1180～1220 ℃ that beginning is melted temperature.
3, can be used as porcelain and join the main raw material of glaze (joining glaze consumption＞30%).Porcelain is joined glaze at present also the precedent of using frit, but existing frit can not be as main batching, and consumption is generally less than 30%.The frit that present technique is produced joins at porcelain that amount ranges is 40～95% in the glaze.
4, adopt the present technique frit to join glaze, can make the porcelain glaze reduce pin hole, improve gloss, glaze is level and smooth, widens firing temperature, stably manufactured.
