Study On And Manufacture Luminescent Glaze Ceramics

This paper makes particular and systemic tests,analyses,investigations of composition and technical capability on HETAI gold mine gangue and GAOYAO white earth in GUANGDONG province.On these basis,mainly taking gold mine gangue and white earth as primary materials and mixing into camwood earth.kaliumfelspar and a ounce steatite to manufacture ceramics.By analyzing mineral and chemical elements of original ceramic bricks,with a great deal of burning experiments,to get a rationly burning regulation.Successfully produce many kinds of ceramics and discuss disfigurements of burned brick and put forward good measures to avoid these to happen.Briefly discuss various issues of luminescent material,basic melted block and luminescent glaze plasm preparation and glazing of new luminescent glaze.Time after time to do low temperature glaze burning experimentations to investigate the inside and outside factors of glaze's quality and luminescent capability.In logical glaze burning regulations to produce very better luminescent glaze ceramics.These are some conclusions through a series of experiments, analyses and surveys:One,quartz,sericite including Eriestone and water mica are main elements in HETAI gold mine gangue.In this material quartz occupies 50-60% around,sericite 14-17% around,else materials much less.Quartz is main object.Containing alkaline clay minerals can be used in ceramics.In exception of iron element,rest mineral elements have nothing to influence the burning regulations.As raw material,gangue is a barren material,containing useable clay and dolomite.Gangue's granularity is very small.mineral makeup single,maleficent impurity minerals little and chemical elements are relatively pure.So gangue is a fine ceramic material.Two,in GAOYAO white earth ,a incompletely airslaked clay on the earth's surface,quartz content is high ,clay minerals such as kaolinite, water kaotinite are relatively lower ,the whole plasticity middle class,fire enduring capability low. After burning,this material takes on hoar color, is a high quality compound ceramics materials,can be used with gangue to reduce manufacture costs.Three,taking gold mine gangue, GAOYAO white earth,camwood earth,kaliumfelspar and little steatite as primary materials.in reference of experiments,receive all kinds of products. 1#.2#.3# prescription bricks' burning temperatures are low, 1130-1170 degree around,high temperature preservation only 30-40 minutes.the whole burning period is 3 hours long.Four.luminescent glaze in experiments is a excellent low temperature rapidly burning glaze.Luminescent material is alkali aluminium acid strontiumEu2+Dy3+ crystals.Basic glaze material is melted block and its melting temperature is 800 degrees.Five,the surface quality and luminescent capability of luminescent ceramics have two aspect effects:buming temperature and burning period.As far as luminescent glaze melts,burning temperature can be lower and burning period can be short.Experiments doing in oxygen gases.has a burning temperature ordinary 850 degree about,Burning period 30-60 minutes,high temperature preservation 2-3 minutes.Six.the elements and natures of brick and glaze affect luminescent glaze ceramics.the containing ratio of luminescent powdery,granularity and glaze thickness all have effects on luminescent ceramics:luminescent powders' quantity 30%,Granularity 200 order.in certain range big thickness can make luminescent capability better.the elements and burning degree affect adjustability between brick and glaze and at the same time to affect glaze surface quality and luminescent capability.Ordinary,brick,glaze's elements very near,burned to some degree.sop ratio a little great can put up luminescent ceramics quality.
