Abstract

The invention discloses a method for manufacturing chinaware with the optical performance of jadeite. The method comprises the following steps of subjecting NaAlSi2O6 solid powders to primary sintering to obtain primarily sintered solid; crushing and grinding the sintered solid to obtain NaAlSi2O6 sintered solid powders; subjecting NaAlSi2O6 sintered solid powders as raw materials to mechanical press molding and then high-temperature sintering in a high-temperature sintering furnace to obtain a ceramic material with the optical performance of jadeite. The low-cost jadeite chinaware is produced by combining ceramic technology and jadeite synthesizing technology. The jadeite chinaware manufactured by the method has the advantages of crystal clear appearance, high transparency and hardness, glassy luster, optical performance of the jadeite and higher ornamental value, which can be further carved to obtain high-grade vessels, artware and high-grade home decorations.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a method for manufacturing ceramics with emerald optical properties. Background technique [0002] Jade has been regarded as auspicious and evil since ancient times. It is a symbol of nobility, purity, elegance, wealth, peace and happiness. Compared with gold and silver, jade is slightly better in appearance. Jadeite is one of the most precious varieties of jadeite. The mineral name of Jadeite is "sodium pyroxene", and some people call it "jadeite". The molecular formula is NaAlSi 2 o 6 . Jadeite is a dense aggregate of countless fine fibrous crystals intertwined, called "felt structure", which is very firm and tough. Jadeite has transparent or translucent glass luster, fine crystal structure, uniform color tone, often with bright green or light green, has strong ornamental value, and is deeply loved by the people of the Chinese nation and Southeast Asian countries. High-...
