Abstract

The invention discloses a brown glaze heat-resistant ceramic pot, which comprises a ceramic pot body and a brown glaze. The base material of the ceramic pot body is composed of: 40-50% of clay, 10-20% of alumina, and 9-13% of alkaline earth %, refractory clay 7‑9%, quartz 15‑20%, the brown glaze base material is composed of: kaolin 33‑36%, quartz 10‑15%, oxide 2‑3%, waste porcelain powder 8‑10% , colorant 10‑12%, dolomite 5‑7%, calcium carbonate 0.6‑1%, calcium phosphate 0.6‑1%, apatite 0.6‑1%, silicon dioxide 6‑8%, alumina 4‑6 %, Calcite 3‑5%, Limestone 1‑2%. In the present invention, zinc oxide, strontium oxide and tin oxide are added to the glaze to improve the glossiness of the glaze, improve the opacity of the glaze, increase the refractive index of the glaze to light, and add waste Porcelain powder not only recycles resources, but also reduces air bubbles and pinholes in the glaze surface, improving the quality of the glaze surface. By strictly controlling the proportion of pigments, the ceramic pots made are bright in color and high in chroma, suitable for widespread promotion .

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a brown-glazed heat-resistant ceramic pot, and at the same time, the invention also relates to a preparation method of a brown-glazed heat-resistant ceramic pot. Background technique [0002] The glaze applied on ceramics is generally made of quartz, feldspar, and clay. After grinding and adding water, it is coated on the surface of the green body and melted by roasting at a certain temperature. When the temperature drops, the glassy surface of the ceramic surface is formed. TLC. It makes ceramics increase mechanical strength, thermal stability, dielectric strength and prevent liquid and gas erosion. Glaze also has the functions of increasing the appearance of porcelain, making it easy to wash and wipe, and preventing it from being stained by dust. [0003] When making brown ceramic pots, the glossiness of the glaze surface made of the existing brown glaze is relatively ...
