High-temperature glaze, preparation method thereof and application of high-temperature glaze in electric vacuum ceramic shell
The invention discloses a high-temperature glaze, a preparation method thereof and application of the high-temperature glaze in an electric vacuum ceramic shell, and belongs to the technical field of ceramic glazes. The high-temperature glaze is obtained through the processes of raw material iron removal, glaze preparation, glaze ball milling, semi-automatic glaze spraying, oxidation sintering and high-temperature hydrogen reduction sintering. The preparation method comprises the following steps: mixing potassium feldspar, kaolin, SiO2, CaCO3 and MgO which meet the requirements of granularity and purity according to a new formula, carrying out ball milling to obtain glaze slip, enabling the glaze slip to reach the specific surface area and specific gravity which meet the process requirements, uniformly coating the glaze slip on the surface of a porcelain body by adopting a semi-automatic glaze spraying technology, controlling the thickness of a coating, and carrying out oxidation sintering and high-temperature hydrogen reduction sintering to obtain the ceramic product. And the glaze slip and the porcelain body are better combined. The high-temperature hydrogen reduction sintering temperature of the prepared high-temperature glaze is improved from the original 1340-1440 DEG C to 1450-1570 DEG C, the glaze surface performance is stable, the glossiness and dielectric property are good, and the product quality is further improved.
本发明公开了一种高温釉及其制备方法和在电真空瓷壳中的应用，属于陶瓷釉料技术领域，采用原料除铁，配制釉料，釉料球磨，半自动喷釉，氧化烧结及高温氢气还原烧结的工艺得到高温釉，将符合粒度和纯度要求的钾长石、高岭土、SiO2、CaCO3和MgO按照新的配方混合，通过球磨得到釉浆，使其达到工艺要求的比表面积和比重，采用半自动化喷釉技术将釉浆均匀涂在瓷体表面，控制涂层厚度，经过氧化烧结和高温氢气还原烧结，使釉浆和瓷体更好结合。制得的高温釉的高温氢气还原烧结温度得到了提高，从原来的1340～1440℃提高到1450～1570℃，釉面性能稳定、光泽度和介电性能良好，产品质量进一步提升。
