Embodiment 1

[0020] Embodiment one, the ratio of bottom glaze and transparent glaze is respectively 90% and 10%.

[0021] The bottom glaze is composed of the following raw materials in parts by weight: 3 parts of ultra-white zirconium silicate, 20 parts of ordinary potassium feldspar powder, 25 parts of albite feldspar, 4 parts of alumina, 9 parts of kaolin and 6 parts of calcined kaolin. The transparent glaze is composed of the following raw materials in parts by weight: 3 parts of calcined zinc oxide, 9 parts of barium carbonate, 30 parts of albite, 0 part of calcined alumina, 13 parts of calcite, 9 parts of calcite, 5 parts of quartz, and 9 parts of kaolin Composed of 12 parts of calcined kaolin.

[0022] Carry out the weighing ratio mixing of raw materials according to the above ratio.

Embodiment 2

[0024] The bottom glaze is composed of the following raw materials in parts by weight: 3 parts of ultra-white zirconium silicate, 20 parts of ordinary potassium feldspar powder, 25 parts of albite feldspar, 4 parts of alumina, 9 parts of kaolin and 6 parts of calcined kaolin. The transparent glaze is composed of the following raw materials in parts by weight: 5 parts of calcined zinc oxide, 7 parts of barium carbonate, 30 parts of potassium feldspar powder, 0.5 parts of calcined alumina, 12 parts of calcite, 10 parts of calcite, 5 parts of quartz, and 9 parts of kaolin Composed of 7 parts of calcined kaolin. The quartz is finely ground quartz after being screened with 325 meshes.

[0025] Carry out the weighing ratio mixing of raw materials according to the above ratio.

Embodiment 3

[0027] The bottom glaze is composed of the following raw materials in parts by weight: 3 parts of ultra-white zirconium silicate, 20 parts of ordinary potassium feldspar powder, 25 parts of albite feldspar, 4 parts of alumina, 9 parts of kaolin and 6 parts of calcined kaolin. The transparent glaze is composed of the following raw materials in parts by weight: 5 parts of burnt zinc oxide, 7 parts of barium carbonate, 30 parts of potassium feldspar powder, 2 parts of calcined alumina, 12 parts of burnt talc, 10 parts of calcite, 5 parts of quartz, and 9 parts of kaolin Composed of 14 parts of calcined kaolin.

Abstract

The invention discloses a glaze material for dark ceramics, which is composed of 88-92% of bottom glaze and 8-12% of transparent glaze calculated by weight, and the bottom glaze is calculated by weight: Composed of 2-5 parts of ultra-white zirconium silicate, 18-22 parts of potassium feldspar powder, 23-27 parts of albite feldspar, 3-5 parts of alumina, 8-10 parts of kaolin and 5-7 parts of calcined kaolin; the transparent glaze is Calculated by parts by weight: 3-7 parts of calcined zinc oxide, 6-10 parts of barium carbonate, 28-32 parts of potassium feldspar powder or 28-32 parts of albite, 0-3 parts of calcined alumina, 11-3 parts of calcined talc 14 parts, calcite 8-12 parts, quartz 4-6 parts, kaolin 8-10 parts and calcined kaolin 7-14 parts. The invention makes the product rich in texture and color, soft and realistic in texture, stable in performance, free from corrosion and uneven cracking.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a glaze for dark ceramic products and a preparation method for the glaze. Background technique [0002] As ceramic products enter millions of households, ceramic glazes are indispensable decorative materials for ceramic products. The existing ceramic glazes can be roughly classified according to their categories and uses as follows: 1. Lead glaze and lead-free glaze; 2. Raw glaze and frit glaze; 3. Glaze for primary firing or secondary firing; 4. Glaze for ceramic tiles, tableware, sanitary ceramics and electric porcelain; 5. Dip glaze, spray glaze, pouring glaze according to the glaze method; Glaze and low temperature glaze; 7. High expansion glaze and low expansion glaze; 8. Firing atmosphere oxidation flame, neutral flame and reducing flame; 9. Color glaze and colorless glaze; 10. Transparent glaze and opacity glaze; 11. Gloss glaze, matt glaze, semi-matt glaze or pattern gl...
