Sintering of Pressed Ceramic Components | Dynamic Ceramic

Full densification is achieved by sintering at temperatures up to 1800°C. The sintering or firing process provides the energy to encourage the individual powder particles to bond or "sinter" together to remove the porosity present from the compaction stages. During the sintering process the "green compact" shrinks by around 40 vol %.

Ceramic - Wikipedia

Ceramics generally can withstand very high temperatures, ranging from 1,000 °C to 1,600 °C (1,800 °F to 3,000 °F). Glass is often not considered a ceramic because of its amorphous (noncrystalline) character. However, glassmaking involves several steps of the ceramic process, and its mechanical properties are similar to ceramic materials.

Chapter 13 Structures and Properties of Ceramics

Bonding in Ceramics (Review of Chapter 2) The atomic bonding in ceramics is mixed, ionic and covalent, the degree of ionic character depends on the difference of electronegativity between the cations (+) and anions (-).
