Porcelain is a compound word of pottery (陶器) and porcelain (磁器), and refers to a product that is molded with inorganic materials such as clay, feldspar, silica, and ceramics alone or mixed and then hardened by applying heat.

Porcelain, due to the characteristics of ceramic materials, creates a clear and clean image and is widely used not only in practical aspects but also in decorative aspects due to its pure sound when beaten, so it is mainly used in dishes such as tableware, teacups, and plates.

Various ceramics have been developed as the demand for ceramics has increased and their uses have been diversified, but the development of ceramics with excellent heat resistance and thermal conductivity suitable for use in cold weather is still insufficient.

<Method for manufacturing heat-resistant ceramics for lighting>

1 is a flowchart showing a method for manufacturing a heat-resistant ceramic for insulation of the present invention.

First, in the first step (S10), a container shape is manufactured by molding a mixture of loess and heat-resistant material.

Specifically, a mixture is prepared by mixing loess and heat-resistant material, and water is added to the mixture to make a dough, and then the dough is used to prepare a container shape.

The heat-resistant material includes at least one of heat-resistant earth, clay mineral, kaolin, clay, talc, silica, and iron, and various designs can be changed according to the purpose of use of the manufactured ceramics.

When mixing the loess and the heat-resistant material, 85 parts by weight of the heat-resistant material is preferably blended with respect to 15 parts by weight of the loess.

If less than 85 parts by weight of the heat-resistant material is mixed with respect to 15 parts by weight of the loess, the heat resistance of the heat-resistant porcelain for charring may be lowered, and if it exceeds 85 parts by weight, the anion emission effect of the loess may be reduced.

In addition, when adding water to the formulation, in order to smoothly perform the kneading operation, it is preferable to add 0.25 to 0.45 parts by weight of water based on 1 part by weight of the formulation.

The container shape is circular to provide a space in which the car is located so that the car can be smoothly carried out.

Next, in the second step (S20), the container is dried.

Specifically, drying is performed to remove moisture from the prepared container. Through the drying process, appropriate strength required for intaglio and firing is given.

The drying is preferably performed for 3 to 4 hours.

If the drying time is less than 3 hours, sufficient drying may not be performed, so the appropriate strength required for intaglio and firing may not appear.

Next, in the third step (S30), the container is engraved.

Specifically, an engraving is performed on the lower surface of the container, and the engraving is mainly composed of a circle and an oblique line based on a central point.

Next, in the fourth step (S40), the container is lubricated.

Specifically, the calcined container is glazed (glazed) to remove absorbency and increase resistance to water or chemicals.

Next, in the fifth step (S50), firing is performed.

Specifically, the glazed container is single-fired at 1210 to 1220°C.

If the firing temperature is less than 1210 ℃, the strength of the finished product is significantly reduced, and if it exceeds 1220 ℃, a problem occurs that the surface is not smooth and smooth.

Hereinafter, the intaglio shape formed on the lower surface of the heat-resistant porcelain for insulation of the present invention will be described in detail through examples.

More specifically, by configuring grooves of various shapes through intaglios at the bottom of the container, it is possible to capture the combustion energy emitted into the atmosphere as much as possible to save energy and uniformly conduct heat.

In addition, the groove provided at the bottom of the container provides frictional force so that the tea leaves do not agglomerate when brewing tea.
