Raw material for low-temperature firing of Longquan celadon and firing method

Abstract

The invention relates to a firing technology for low-temperature firing of celadon and aims to provide a raw material for low-temperature firing of Longquan celadon and a firing method. According to the invention, as for a blank body and glaze, a raw mineral material and a chemical raw material which are generally used by the Longquan celadon are adopted for matching, and nano calcium carbonate and zinc borosilicate glass powder are also contained; the nano particle high-specific external surface activity and various additives are combined with a cooling down mechanism, so as to allow the Longquan celadon to be fired under 1,150-11,800 DEG C, and the problems that the Longquan celadon is high in sintering temperature and high in energy consumption are solved. The product has the characteristics of high finished product ratio, good porcelain quality, high strength and the like, and has a wide application prospect.

Description

technical field

[0001] The invention belongs to the technical field of material science, and in particular relates to a firing method of Longquan celadon, which is suitable for manufacturing various high-grade daily-use porcelain and art porcelain, in particular to a preparation method of firing Longquan celadon at low temperature. Background technique

[0002] Longquan celadon is known as the "flower of celadon". It is green and crystal clear, as moist as jade, and has a profound influence on Chinese culture. In 2009, it was approved to be included in the "Representative List of Intangible Cultural Heritage of Humanity". At the 2010 World Expo, it perfectly demonstrated the charm of porcelain through the ages, poems and paintings in the south of the Yangtze River, and the value of Longquan industrial celadon is widely accepted by people. However, Longquan celadon uses a unique raw material of purple gold clay and a unique "secondary firing" process, which is very sensitive ...
