Description

It is placed in the manufacture craft of Nixing pottery heated under naked light
Technical field
The present invention relates to the manufacture craft of Nixing pottery, and in particular to a kind of making of the Nixing pottery for being placed in being heated under naked light Technique.
Background technology
Qiezhou Nixing pottery and yixing purple sand pottery, Sichuan Rongchang County pottery and Yunnan Jian Shui potteries, and claim the big name of China four to make pottery.Nixing pottery Manufacture craft include prepare blank, blank forming, finishing base substrate, body drying, base substrate decoration, base substrate fire and polishing grinding Operation.Raw material used by Nixing pottery includes eastern mud and western mud, and eastern mud is the soil from the Jiang Yidong that admires for crossing Qiezhou urban district, is Mild-clay, color is yellow-white, and containing micro quartz sand, plasticity is good, is easy to shaping, but refractoriness is quite low, individually fires and holds It is yielding；Western mud is the soil of region to the west of river by the emperor himself, is a kind of iron-holder purple mudstone higher, and color is aubergine, superficial layer There is a small amount of irony to contaminate, be hard paste, fire resistance is good, it is not easy to deform, but poor plasticity, it is difficult to separately formed, by east Mud and western mud are matched with constant weight and mixed, and the series of process such as ground, dehydration is made plastic blank.The base of Nixing pottery SiO in material2Content is up to 67.7%, Al2O3Content is 18.14%, a part of SiO2With Al2O3Reaction generation mullite, Mo Lai The thermal coefficient of expansion of stone is higher；A part turns into Free quartz, and Free quartz can occur crystal transfer at high temperature, becomes from quartz Into cristobalite, the coefficient of expansion of cristobalite is more much bigger than quartz, and quartz can produce larger volume swollen to cristobalite conversion It is swollen, so as to cause the thermal coefficient of expansion of Nixing pottery vessel larger, typically 5 × 10-6/ DEG C more than.Therefore Nixing pottery vessel conduct When being used under the conditions of naked light, heating temperature can reach 600 DEG C to cooking ware, still suffer from the change of frequent thermal fluctuation, very Easily burst during boiling.Therefore, Nixing pottery vessel can only be used as ceramics ware for daily use, such as conventional cup, dish, tea Kettle, vase, and cannot function as cooking ware and used under the conditions of naked light.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of manufacture craft of the Nixing pottery for being placed in and being heated under naked light, The Nixing pottery vessel coefficient of expansion that the technique is made is low, can be used under the conditions of naked light as cooking ware and not ruptured.
The technical scheme that the present invention is provided is a kind of manufacture craft of the Nixing pottery for being placed in and being heated under naked light, including is prepared Blank, blank forming, finishing base substrate, body drying, base substrate are fired, and the blank is made up of the raw material of following weight portion：Eastern mud 6 ~4 parts, 4~6 parts of western mud, MnCl20.1~0.5 part；
It is during base substrate sent into kiln, in temperature-rise period, when temperature is warming up to 700 DEG C, to base that the base substrate is fired Body is forced into 10~15MPa, and when temperature rises to 1100 DEG C, stops pressurized treatments.
Eastern mud and western mud main component are SiO2And Al2O3, during high-temperature firing, SiO2And Al2O3Aluminium silicon can be generated Spinelle, when more than 1000 DEG C, aluminium silicon spinel can be further converted to mullite.Mullite crystal structure can be regarded as The structural evolution of sillimanite, its structure cell is made up of 4 sillimanite structure cells, and each sillimanite structure cell is by 4 Al2O3·SiO2 Composition.Therefore, mullite structure cell is equivalent to 16Al2O3·SiO2's.Mullite belongs to orthorhombic system, and containing axle is parallel to, it contains It is parallel to axle AlO6Octahedron, these AlO6The octahedra SiO by transverse direction4Tetrahedron is connected.The application is added in blank MnCl2, in 700~1100 DEG C of baking temperature range, the SiO in blank2And Al2O3Activated by bivalent manganese, promote SiO2With Al2O3Mullite is converted into, due to 10~15MPa of condition of high voltage, SiO4Tetrahedron can combine to form N and save ring by bridging oxygen key, AlO6It is octahedra to be connected to form the crystal structure with big cavity structure with N section rings.When crystal is heated, particle thermal vibration is shaken Width increases, and big cavity makes crystal not have obvious expansion, thus shows the less coefficient of expansion.
Preferably, the weight portion of each raw material of blank is：6 parts of eastern mud, 4 parts of western mud, MnCl20.1~0.5 part.
It is further preferred that the weight portion of each raw material of blank is：6 parts of eastern mud, 4 parts of western mud, MnCl20.3~0.5 Part.MnCl2Addition when being eastern mud and western mud gross weight 3~5%, activation effect is best.
It is, by base substrate feeding kiln, when being warming up to 1150~1200 DEG C, to stop heating that the base substrate is fired, and is gone out after cooling Kiln, completes to fire；When temperature is warming up to 700 DEG C, 10~15MPa is forced into base substrate, when temperature rises to 1100 DEG C, stopped Pressurized treatments.
Preferably, it is that dried base substrate is put into kiln that the base substrate is fired, to heat up per hour 20~30 DEG C Programming rate rise to 250~350 DEG C, then rise to 700 DEG C with 80~100 DEG C of the programming rate of heating up per hour, then with every The programming rate of 40~60 DEG C of hour intensification rises to 1150~1200 DEG C, stops heating, kiln discharge after cooling.
Compared with prior art, the Nixing pottery vessel that the present invention makes have excellent heat-resisting acute degeneration and preferably machinery Intensity, thermal coefficient of expansion can be down to 2 × 10-6/ DEG C (Rt~800 DEG C) below, can directly be used on various thermals source, it is prolonged without Cracking, can meet QB/T2580-2002《Fine ceramics cooking device》Standard requirement.
