Forsterite (Magnesium Silicate) (Mg₂(SiO₄)

Forsterite is a crystalline Magnesium Silicate (Mg₂(SiO₄) that is a member of the Olivine Group. It is an excellent birefringent material with a wide transparency range that has extremely low electrical conductivity and superior mechanical properties. It is calcined and milled under controlled conditions and can be modified to meet priority specifications.
Synthetic forsterite is available, and it has as high an iron content (<11%) as Fayalite.
Theoretical Analysis

MgO= 44-47%, and SiO₂= <40%

Typical Applications

Forsterite is used as a substrate for electronics applications and in the manifolds of solid oxide fuel cells. It is also used in thick films, ceramic metal seals, and high-temperature bonding agents. It has potential as a biomaterial for implants.

Sustainable Qualities

Forsterite, also known as magnesium silicate, is considered a sustainable material because it is abundant in nature and does not require energy-intensive processes to produce. Additionally, it is inert and non-toxic, making it safe for the environment and human health. Forsterite is also biodegradable, which means it can break down into natural environmental components over time.
