Ionic ceramics
Web4 jul. 2024 · Because ionic compounds contain both cations and anions rather than only neutral atoms, however, they exhibit additional types of defects that are not possible in metals. The most straightforward variant is a substitutional impurity in which a cation or an anion is replaced by another of similar charge and size.

WebCeramic Bonding. Recall that the predominant bonding for ceramic materials is ionic bonding. In ionic bonding, a metal atom donates electrons and a nonmetal atom accepts electrons. This electron transfer creates positive metal ions (cations) and negative nonmetal ions (anions), which are attracted to each other through coulombic attraction. Web28 sep. 2024 · The ionic and covalent bonds of ceramics are responsible for many unique properties of these materials, such as high hardness, high melting points, low thermal expansion, and good chemical resistance, but also for some undesirable characteristics, foremost being brittleness, which leads to fractures unless the material .
