Iron safflower glazed porcelain prepared from ferronickel tailings slag

Abstract

The invention relates to the technical field of ceramic and concretely relates to an iron-red fancy glazed porcelain prepared from josephinite tailing slag. The iron-red fancy glazed porcelain prepared from josephinite tailing slag has a blank formula comprising josephinite tailings, clay, pyrophillite, quartz, alkalifeldspar and limestone and has a glaze formula comprising josephinite tailings, potassium feldspar, clay, quartz, iron oxide and phosphoric pentoxide. The iron-red fancy glazed porcelain comprises a lot of dispersed small liquid drops. The glaze is brown. Bean-shaped spots and blocks are distributed on the glaze and are orange. Iron oxide in the josephinite tailings is not melt at a high temperature and can individually adhere to the glaze surface in a liquid drop form, and after cooling, large red flower-shaped iron crystals are formed so that iron-red fancy glaze is formed. The waste josephinite tailings are recycled so that solid waste discharge is reduced, a porcelain clay raw ore use amount is reduced and ore product resource development is reduced.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to an iron safflower glazed porcelain prepared from ferronickel tailings slag. Background technique [0002] With the rapid development of the economy and society, people's quality of life is improving day by day, and the concept of consumption is also constantly changing, requiring that ceramic products should not only be practical, but also artistic and ornamental. The existing glaze color can be divided into high temperature glaze and low temperature glaze according to the firing temperature; according to the appearance characteristics, it can be divided into transparent glaze, opacity glaze, color glaze, glossy glaze, matte glaze, crackle glaze (open sheet), crystal glaze and so on.

AI Technical Summary

Problems solved by technology

[0003] my country is rich in mineral resources and has a huge reserve. After mining and purification, the tailings are not used, and the tailings are piled up like mountains, which not only seriously pollutes the surrounding area, but also wastes a lot of resources.

Tailings occupy a large amount of land, causing problems such as soil erosion and environmental pollution. In recent years, people have paid attention to the comprehensive utilization of tailings. For example, Chinese patent CN103145449B discloses "a method for preparing iron tailings into ceramic frit glaze ", this method provides the utilization approach of iron tailings and the method for preparing black glaze, brown glaze, brown glaze, and for example Chinese patent CN 104529549A discloses "tea powder glaze prepared with iron tailings and its preparation method". This method provides The method of preparing tea glaze by clarifying the utilization approach of iron tailings. The above-mentioned methods all use iron tailings to prepare ceramic glazes. Due to the limitation of raw materials and formula structure, the porcelain of iron safflower glaze prepared by ferronickel tailings slag is currently technology, there is no record of relevant literature
