Embodiment 1

[0007] Example 1, put the porcelain body of wrapped cadmium selenium red glaze into an industrial batch microwave bell furnace, the microwave frequency is 915MHz, the temperature is raised to 1090°C within 100 minutes, and the temperature is kept for 10 minutes. After turning off the microwave source, let it cool down to room temperature with the furnace. During sintering, the atmosphere is an oxidizing atmosphere, and the pressure in the furnace is 1.0×10 5 Pa. Measure the temperature with an infrared thermometer. After being released from the oven, after inspection, the glaze surface of the fired sample is bright red, uniform in color and good in gloss. 150°C lower than traditional sintering temperature.

Embodiment 2

[0008] Example 2, put the green body coated with cadmium selenium red glaze into an industrial continuous microwave sintering furnace, the microwave frequency is 2.45GHz, the temperature is raised to 1150°C within 120 minutes, and the temperature is kept for 20 minutes. Cool to room temperature with the furnace. Measure temperature with thermocouple. During sintering, the atmosphere is an oxidizing atmosphere, and the pressure in the furnace is 1.0×10 5 Pa. After being released from the oven, after inspection, the glazed surface of the burned sample is bright red, uniform in color, good in gloss, and the appearance quality meets the standard. 100°C lower than traditional sintering temperature.

Abstract

The invention relates to a parcel cadmium-selenium red glaze microwave sintering method that is made up from sending the glaze material mixed with cadmium sulfoselenide parcel color material into industrial microwave sintering furnace under the condition of 300Mhz-300GHz frequency, 600-1600 degree centigrade temperature, cooling and drawing a charge. Thus, the butt glaze would be warming up equally and the glaze material would react quickly. It is simple technology, and short producing cycle. The producing efficiency and economic benefits are improved.

Description

technical field [0001] The invention relates to a preparation method of ceramic glaze, in particular to a sintering method of wrapped cadmium selenium red glaze. Background technique [0002] Cadmium sulfur selenide wrapped color [Cd(Se x S 1-x )-ZrSiO 4 ] with cadmium sulfur selenide [Cd(Se x S 1-x )] The unique vividness and certain stability of the pigment have been widely used in the decoration of ceramic products. However, when the encapsulating pigment is added to the basic glaze to form an encapsulating cadmium-selenide red glaze, the glaze in a molten state under high temperature conditions will dissolve and enclose in cadmium sulfoselenide [Cd(Se x S 1-x )] zirconium silicate (ZrSiO 4 ) protective layer, which reduces the wrapping rate and affects the color stability. Therefore, when sintering the encased cadmium selenium red glaze, if the reaction speed of the glaze can be increased and the sintering temperature of the glaze can be reduced, it will be very ...
