A kind of light blue Jun porcelain and its firing method

Abstract

The invention discloses light blue jun porcelain and a firing method thereof. The light blue jun porcelain is sintered from a green body and a glaze on the green body surface, wherein the glaze comprises melilite, quartzite, muscovite, potassium feldspar, asbolite, zinc, tin dioxide, iron oxide, magnesium oxide, titanium dioxide, sodium hydroxide, zirconium silicate, potassium oxalate and spodumene; the sintering raw materials of the green body comprise a main material, a pore forming agent and filler; the pore forming agent comprises fine silicon carbide powder, sodium chloride and soda lime; the filler comprises fine kyanite powder, activated alumina micropowder and bone meal. Silicon carbide, sodium chloride and soda lime are mixed with the main material and serve as the pore forming agent, so that sintered porcelain green body can contain a plurality of open pores, the pores are shrunk obviously by adding the kyanite powder with volume expansion at a high temperature, small pores are formed in the porcelain and on the porcelain surface, combination with the glaze is facilitated, flow lines occur more easily in a sintering process, and the generation probability of the porcelain with the flow lines is increased.

Description

technical field [0001] The invention belongs to ceramics in the field of inorganic non-metallic materials, in particular to light blue Jun porcelain and its firing method. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty.

Problems solved by technology

[0004] In order to solve the problem that the existing Jun porcelain with flow lines in the firing process is very dependent on the operating experience of skilled workers and the yield is very low, the present invention provides a light blue Jun porcelain and its firing method. By firing the plain tire with special micro-pores on the surface and inside, and with a unique glaze, it is easier to appear flow lines when the plain tire is glazed and fired
