• Germany: Hydraulic calcium hydrosilicate (hCHS)-based cement producer Celitement has gone from being a Schwenk-affiliated company to a full subsidiary of the 5.76Mt/yr integrated capacity cement producer. Celitement plans to upgrade its pilot plant at the Karlsruhe Institute of Technology (KIT), Baden-Württemberg, to increase production capacity. When this is completed, it will offer ‘single-digit tonne’ deliveries to ‘select investors’ and begin ‘large-scale practical testing.’ These will determine the feasibility of establishing an industrial Celitement plant.

• Magnesium hydrosilicate is 11% water by weight and is stable at temperatures and pressures found in Earth’s core. During Earth’s formation, the solid core of iron that we know today did not exist yet, and magnesium hydrosilicate existed in its place. Magnesium hydrosilicate is a product of chondrites, which are meteoric rocks thought to be found in most rocky planets. “Magnesium hydrosilicate will be inevitably formed if you subject the chondrite to pressures above 200 Gigapascals,” Oganov said.

• In the case of very large planets from outside our solar system that can perhaps contain water and thus support life (the hypothetical “super-Earths”), pressures stabilizing the magnesium hydrosilicate can exist even outside the core, locking large amounts of water indefinitely. “As a result, super-Earths can have a much greater water content and still support the existence of exposed continents,” concluded study co-author Xiao Dong, a physicism at Nankai University.
