What does "white China" refer to in materials


In materials science, the term "white China" refers to a specific type of ceramic material known for its bright white color and high purity. This material is commonly used in various industries for its unique properties and aesthetic appeal.

Properties of White China

White China possesses several notable properties that make it desirable for various applications:


White China is characterized by its high purity levels, often exceeding 99.5%. This purity ensures minimal impurities in the material, resulting in enhanced performance and durability.


The density of white China typically ranges from 2.8 to 3.1 grams per cubic centimeter (g/cm³), making it relatively lightweight compared to other ceramic materials. This property contributes to its ease of handling and transportation.


White China exhibits exceptional hardness, with a Mohs hardness rating of approximately 7.5 to 8. This hardness makes it highly resistant to scratching and wear, prolonging its lifespan in various applications.

Thermal Conductivity

With a thermal conductivity ranging from 2.5 to 3.5 watts per meter-kelvin (W/(m·K)), white China demonstrates good heat conduction properties. This feature makes it suitable for applications requiring heat resistance and thermal stability.

Chemical Resistance

White China is highly resistant to chemical corrosion, making it suitable for use in harsh environments where exposure to acids, alkalis, and other corrosive substances is a concern.

Applications of White China

Due to its exceptional properties, white China finds application in various industries, including:

Tableware and Kitchenware

White China is commonly used in the production of tableware and kitchenware, such as plates, bowls, mugs, and teapots. Its bright white color and smooth texture add elegance to dining experiences.

Electrical Insulation

In the electrical industry, white China is utilized for insulating components due to its high dielectric strength and resistance to electrical conductivity. It is employed in the manufacture of insulators, circuit breakers, and other electrical components.

Dental and Medical Equipment

The biocompatibility and chemical resistance of white China make it suitable for dental and medical applications. It is used in the fabrication of dental crowns, bridges, and implants, as well as surgical instruments and laboratory equipment.

Architectural and Decorative Tiles

White China tiles are popular in architectural and decorative applications due to their aesthetic appeal, durability, and ease of maintenance. They are used for flooring, walls, and facades in residential, commercial, and institutional buildings.


In conclusion, white China is a versatile ceramic material prized for its purity, hardness, thermal conductivity, and chemical resistance. Its wide range of applications across various industries highlights its importance in modern manufacturing and design. To learn more about white China and its uses, visit here.
