Table 1: the chemical analysis composition (%) of brown glaze:
| Si 2O | Fe 2O 3 | Al 2O 3 | CaO | MgO | K 2O | Na 2O | ?IL | Cr 2O 3 | MnO 2 |
| 60-65 | 2-3 | 13-16 | 4-6 | 2-4 | 2-4 | 0.2-0.6 | 4-7 | 1-3 | 1-3 |
Table 2: the physicals of brown glaze:
Table 3: performance after the burning of brown glaze:
Compared with prior art, advantage of the present invention is: owing to having added toner can reduce the physical strength of glaze, increased the calcined bauxite in powder of certain component in formula for this reason.In the formula, Zuoyun soil and water-washed kaoline have the effect that strengthens the glaze physical strength simultaneously.Can form good middle layer after glazing, increase substantially the flexural strength of porcelain more than 35%, property indices all meets the demands.Being widely used ferric oxide in the formula of electroceramics palm fibre glaze reaches common understanding in the industry as tinting material.Fe
2o
3fusing point be 1560 ° of c, color is by red to brown, it has very large unstable, Fe during high temperature
2o
3change into the tendency of FeO at a low price.Along with the difference that furnace atmosphere and oxygen are pressed, Fe
2o
3also can come and go with the ratio of FeO, thereby make glaze be different colours.Yet owing in brown glaze, introducing Fe
2o
3tinting material after, reduced greatly the arc resistance of glaze, therefore allocating Fe into
2o
3the time also allocate accordingly certain MnO into
2and Cr
2o
7can increase its electric arc.Glaze for electric porcelain is a kind of very complicated silicate compound, consider physicochemical property and the stability of various compounds.The present invention has overcome above-mentioned defect, and the glaze colouring effect is good, and color distribution is even, and the defects such as no color differnece are filled up the blank of this type of glaze for electric porcelain, are worthy of popularization.
Above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
