Ceramic materials are widely used in various industries due to their unique properties, such as high hardness, thermal stability, and chemical resistance. Based on the references provided, ceramic materials can be classified into seven categories: tableware, cookware, wall tile, sanitaryware, structural ceramics, refractories, and technical (advanced) ceramics. These classifications are based on their applications and properties. Additionally, sintered ceramics, a subset of technical ceramics, are further divided into silicate ceramics, non-oxide ceramics, and oxide ceramics. Each category serves specific purposes and is tailored to meet the demands of different industries.

Key Points Explained:

1. Tableware

   • Tableware includes items like plates, bowls, cups, and saucers made from ceramic materials.
   • These products are designed for everyday use and are often glazed to make them non-porous and easy to clean.
   • Common materials include porcelain and earthenware, which are known for their aesthetic appeal and durability.

2. Cookware

   • Ceramic cookware includes pots, pans, and baking dishes.
   • These products are valued for their heat resistance and non-stick properties, making them ideal for cooking and baking.
   • They are often coated with ceramic glazes to enhance their performance and longevity.

3. Wall Tile

   • Ceramic wall tiles are used for decorative and functional purposes in kitchens, bathrooms, and other interior spaces.
   • They are known for their durability, water resistance, and ease of maintenance.
   • Wall tiles are typically made from clay and other natural materials, which are fired at high temperatures to achieve hardness and strength.

4. Sanitaryware

   • Sanitaryware includes ceramic products like toilets, sinks, and bathtubs.
   • These items are designed for hygiene and durability, often featuring smooth, non-porous surfaces that are easy to clean.
   • Porcelain is a common material used in sanitaryware due to its strength and resistance to staining.

5. Structural Ceramics

   • Structural ceramics include bricks, roof tiles, and other building materials.
   • These products are essential for construction due to their strength, durability, and resistance to environmental factors like weather and fire.
   • They are typically made from clay and other natural materials, which are molded and fired to create strong, long-lasting structures.

6. Refractories

   • Refractory ceramics are used in high-temperature applications, such as furnace linings, kiln insulation, and metal crucibles.
   • These materials are designed to withstand extreme heat and thermal shock without degrading.
   • Common refractory materials include alumina, silica, and magnesia, which have high melting points and excellent thermal stability.

7. Technical (Advanced) Ceramics

   • Technical ceramics, also known as advanced ceramics, are engineered for specific applications that require exceptional performance.
   • These ceramics are further divided into three main groups:
     • Silicate Ceramics: Composed primarily of silicon and oxygen, these ceramics are used in applications requiring high thermal and electrical insulation.
     • Non-Oxide Ceramics: These include materials like silicon carbide and boron nitride, which are known for their high strength and resistance to wear and corrosion.
     • Oxide Ceramics: Materials like alumina and zirconia fall into this category, offering high hardness, thermal stability, and chemical resistance.
   • Technical ceramics are used in industries such as aerospace, electronics, and medical devices, where performance and reliability are critical.

By understanding these seven classifications, purchasers can make informed decisions when selecting ceramic materials for specific applications. Each category offers unique properties and benefits, making ceramics a versatile and essential material in various fields.
