Problems solved by technology

However, as a pot for daily heating of food, the most important thing is heat resistance. Compared with metal pots, ceramic pots have relatively poor heat resistance. For milder cooking methods such as boiling and steaming, due to Water protection, the bottom of the pot is heated more evenly, and the ceramic pot is comparable to or even better than the metal pot. Surfaces are vulnerable to damage or even cracking

Embodiment 1

[0018] This embodiment discloses a heat-resistant ceramic pot, and the manufacturing method includes the following steps:

[0019] (1) Preparation of green body: get the blank by weight parts: 17 parts of chapierite, 16 parts of demantoid, 4 parts of zircon, 9 parts of black mud, 2 parts of alumina, 3 parts of sillimanite, 2 parts of phillips 7 parts of bamboo charcoal powder, 5 parts of goose pipe stone, 12 parts of glauconite. After mixing, put it into a ball mill for wet ball milling. The amount of water added during ball milling is calculated as: 25% by weight based on the weight % of the water weight to the water weight and the total dry material. After being stale for 24 hours, pass through a 200-mesh sieve to form a mud for subsequent use;

[0020] (2) Prepare the glaze: get the glaze in parts by weight: 2 parts of barium carbonate, 18 parts of burnt talc, 4 parts of sodium carbonate, 25 parts of glaze fruit, 1 part of tin oxide, 19 parts of silicon dioxide, 3 parts of ...

Embodiment 2

[0024] This embodiment discloses a heat-resistant ceramic pot, and the manufacturing method includes the following steps:

[0025] (1) Preparation of green body: get the blank by weight parts: 23 parts of chapierite, 11 parts of demantoid, 8 parts of zircon, 5 parts of black mud, 5 parts of alumina, 1 part of sillimanite, 5 parts of phillips 3 parts of bamboo charcoal powder, 8 parts of goose tube stone, and 9 parts of glauconite. After mixing, put it into a ball mill for wet ball milling. The amount of water added during ball milling is calculated as: 30% by weight based on the weight of the water weight to the water weight and the total dry material. After being stale for 20 hours, pass through a 250-mesh sieve to form a mud for subsequent use;

[0026] (2) Prepare the glaze: get the glaze in parts by weight: 4 parts of barium carbonate, 12 parts of burnt talc, 7 parts of sodium carbonate, 18 parts of glaze fruit, 3 parts of tin oxide, 14 parts of silicon dioxide, 6 parts of...

Embodiment 3

[0030] This embodiment discloses a heat-resistant ceramic pot, and the manufacturing method includes the following steps:

[0031] (1) Preparation of green body: get the blank by weight parts: 20 parts of chapierite, 12 parts of demantoid, 6 parts of zircon, 7 parts of black mud, 3 parts of alumina, 2 parts of sillimanite, 4 parts of phillips 5 parts of bamboo charcoal powder, 7 parts of goose pipe stone, 11 parts of glauconite. After mixing, put it into a ball mill for wet ball milling. The amount of water added during the ball milling is calculated as: 35% by weight based on the weight of the water weight to the water weight and the total dry material. After being stale for 18 hours, pass through a 280-mesh sieve to form a mud for subsequent use;

[0032] (2) Prepare the glaze: get the glaze in parts by weight: 3 parts of barium carbonate, 15 parts of burnt talc, 5 parts of sodium carbonate, 22 parts of glaze fruit, 2 parts of tin oxide, 16 parts of silicon dioxide, 4 parts ...

Abstract

The invention provides a heat-resistant ceramic pot. A manufacturing method of the heat-resistant ceramic pot comprises the following steps: (1) preparing a green body: taking raw materials of the green body in parts by weight, mixing the raw materials, putting the mixture into a ball mill for wet ball milling, ageing, and sieving with a 200 to 280-mesh sieve to obtain green body mud for later use; (2) preparing glaze: taking glaze raw materials in parts by weight, uniformly mixing, carrying out wet grinding for 5 to 8 hours, and sieving with a 300 to 325-mesh sieve to obtain 0.05% of screen residue, thereby obtaining glaze slip for later use; (3) carrying out slip casting on the blank mud to form a pot blank, drying, biscuiting at 880 to 1080 DEG C, carrying out heat preservation for 3 to 5 hours, and cooling to room temperature for later use; and (4) glazing the pot blank, drying, and firing in a kiln. The prepared heat-resistant ceramic pot is good in glossiness, glittering and translucent in glaze surface, free of pinholes, proper in thermal expansion coefficient, durable, easy to clean and suitable for high-temperature quick-firing cooking modes such as frying, frying and stir-frying, the thermal shock resistance of the heat-resistant ceramic pot does not crack after one-time heat exchange at the temperature of 550 to 20 DEG C, and the water absorption rate of the heat-resistant ceramic pot is within 5%.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a heat-resistant ceramic pot. Background technique [0002] Ceramic pots are ideal cooking utensils for homes and restaurants. They have unique advantages in cooking, stewing, frying, and frying food, and are healthy and environmentally friendly. However, as a pot for daily heating of food, the most important thing is heat resistance. Compared with metal pots, ceramic pots have relatively poor heat resistance. For milder cooking methods such as boiling and steaming, due to Water protection, the bottom of the pot is heated more evenly, and the ceramic pot is comparable to or even better than the metal pot. The surface is vulnerable to damage or even cracking. Contents of the invention [0003] The object of the present invention is to provide a heat-resistant ceramic pot with proper thermal expansion coefficient, good thermal shock resistance and durability. [0004] The object of the...
