Temperature: 850C+

Description:Sintering and densification
Type:State Change

Notes

As temperature increases, particles can begin to bond even though no flux is present to produce a glass to cement particles together (called sintering). As temperature increases, densification occurs as particles realign in increasingly closer contact (forming increasingly tighter bonds as area-of-contact increases). The sintering particles undergo various structural and chemical changes that factor into the matrix being formed, some of these changes involve evolution of gases.

  • (Glossary) Sinter, sintering

    The term "sintered" refers to the particle-to-partice bonding and packing that occurs within a ceramic matrix as temperature increases. Sintering is a process as well as a state. Sintered bodies are not vitrified; the process occurs without any glass development (melting) to glue particles together....
