Ceramic product with metallic luster and preparation method thereof
The invention discloses a ceramic product with metallic luster, the ceramic product comprises a green body, a ground glaze layer, a cover glaze layer and a transparent glaze layer, the ground glaze layer comprises 35-45 parts of potassium feldspar, 25-30 parts of clay, 15-20 parts of white corundum, 5-8 parts of talc, 5-8 parts of bentonite, 5-8 parts of zirconium silicate and 5-7 parts of zinc oxide; the cover glaze layer comprises 30-35 parts of quartz, 20-25 parts of feldspar, 10-15 parts of talcum powder, 8-15 parts of mica, 5-10 parts of zirconium silicate, 5-8 parts of lithium chinastone and 1-5 parts of pigment A; and the transparent glaze layer is composed of transparent frits and a pigment B. Through the component design of the ground glaze, the cover glaze and the transparent glaze, the thermal expansion coefficient difference between the two layers of glaze is small, and the shrinkage rate is small; the ground glaze and the cover glaze are firstly subjected to low-temperature firing, transparent glaze pouring and then high-temperature firing, a stable glaze layer can be formed, uniform and compact microcrystal grains are generated, and the metallic luster is good. And the stress between glaze layers is reduced through twice firing, and the yield is improved.
本发明公开了一种具有金属光泽的陶瓷制品，包括坯体、底釉层、面釉层和透明釉层，所述底釉层包括：钾长石35～45份、粘土25～30份、白刚玉15～20份、滑石5～8份、膨润土5～8份、硅酸锆5～8份、氧化锌5～7份；所述面釉层包括：石英30～35份、长石20～25份、滑石粉10～15份、云母8～15份、硅酸锆5～10份、锂瓷石5～8份、色料A 1～5份；所述透明釉层由透明熔块和色料B组成。本发明通过底釉、面釉和透明釉的组分设计，使两层釉之间热膨胀系数相差不大，收缩率小；底釉和面釉先经过低温烧制，淋透明釉后再高温烧制，能够形成稳定的釉层，并产生均匀致密的微晶晶粒，金属光泽好。且两次烧制降低釉层间的应力，提高良品率。
