Ceramic Testing

Ceramic Testing

Ceramic materials are a type of inorganic non-metallic materials made by shaping and high-temperature sintering natural or synthetic compounds. They have the advantages of high melting point, high hardness, high wear resistance, and resistance to oxidation. They can be used as structural materials, cutting tool materials, and due to their certain special properties, they can also be used as functional materials. Different testing institutions may have different focuses on the items and standards for ceramic testing. Here, we will take Keji Testing as an example to introduce the main testing items and standards for ceramic testing. The inorganic testing center of Keji has rich experience in testing ceramic materials: including ceramic density, ceramic whiteness, ceramic composition, and ceramic fire resistance testing, etc.
