Ceramics are inorganic, non-metallic materials produced by shaping and firing at high temperatures.
Based on composition, processing method, and application, ceramics are commonly classified into five main types.

What are the 5 types of ceramics?
Ceramics are classified based on their composition and application.
The five main types are traditional ceramics, advanced ceramics, oxide ceramics, non-oxide ceramics, and glass ceramics.
Each type has distinct properties such as heat resistance, hardness, and electrical insulation.
They are widely used in construction, electronics, medical, and aerospace fields.
Below is a detailed explanation of the 5 types of ceramics, suitable for exams and manufacturing studies.
