Ferric titanium dull kiln star spot variable composite color material and star spot glaze

Abstract

The invention relates to starred composite pigment material and a starred glaze in a ferrotitanium dark kiln with a composition of composite pigment material by wt.% is: Fe2O3 30-60%, Al2O3 5-20%, TiO2 10-30% and ZnO 5-20%; a composition of material of the starred glaze by wt.% is: albite 30-60%, quartz 5-15%, stalactite 5-15%, alumina 5-15%, barium carbonate 5-20%, zinc oxide 5-15%, SuZhou soil 1-5%, talcum 3-8%, and composite pigment 5-20%. The invention produces the pigment by co-reacting the ferric oxidepigment and titanium oxide and other materials with a low cost. The advantages of pigment are that chemical activity is great and the colour generation is stable. The starred glaze product is made by conventional ceramic glazing system with a good quality and a nice decoration effect. The starred is naturally formed by co-reacting of a seeding agent and other flux material in a high temperature and is baked under the oxidation atmosphere by tunnel kiln so it is simple-produced and simple-controlled.

Description

technical field [0001] The invention relates to an iron-titanium matte kiln variable star-point composite color material and a star-point glaze, belonging to the technical field of ceramics. Background technique [0002] The art of ceramic decoration has a long history like ceramic production, and is an important part of beautifying ceramic products. With the improvement of people's living standards, the decorative requirements for ceramic products are also getting higher and higher. [0003] The star point glaze products on the market are all glazed by spraying or particle method, which is cumbersome, low production efficiency, and the density of star points is variable, so the appearance effect is difficult to be consistent. [0004] The kiln-changing glaze products of Jun kiln and Ru kiln are mostly fired in a reducing atmosphere, which requires high firing and difficult control, and it is difficult to meet the requirements of large-scale production of daily-use ceramic p...

AI Technical Summary

Problems solved by technology

[0003] The star point glaze products on the market are all glazed by spraying or granule method. The process is cumbersome, the production efficiency is low, and the density of star points is not fixed, so the appearance effect is difficult to be consistent.

[0004] Most of the kiln-changing glaze products of Jun Kiln and Ru Kiln are fired in a reducing atmosphere, which requires high firing and difficult control, and it is difficult to meet the requirements of mass production of daily-use ceramic products.
