Zirconium silicates have also been studied for potential use in medical applications. For example, ZS-9 is a zirconium silicate that was designed specifically to trap potassium ions over other ions throughout the gastrointestinal tract. [4] Zirconium silicate is also used as foundry sands due to its high thermal stability.
Zircon (/ ˈ z ɜːr k ɒ n,-k ən /) [7] [8] [9] is a mineral belonging to the group of nesosilicates and is a source of the metal zirconium. Its chemical name is zirconium(IV) silicate, and its corresponding chemical formula is Zr SiO 4. An empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x ...

[5] A procedure for producing mesoporous materials (silica) was patented around 1970, [6] [7] [8] and methods based on the Stöber process from 1968 [9] were still in use in 2015. [10] It went almost unnoticed [11] and was reproduced in 1997. [12] Mesoporous silica nanoparticles (MSNs) were independently synthesized in 1990 by researchers in ...
Hafnium silicate (HfSiO 4) is a silicate of hafnium, and it is a tetragonal crystal. [23] Thin films of hafnium silicate and zirconium silicate grown by atomic layer deposition, chemical vapor deposition or MOCVD, can be used as a high-k dielectric as a replacement for silicon dioxide in modern semiconductor devices. [24]
Materials which have received considerable attention are hafnium silicate, zirconium silicate, hafnium dioxide and zirconium dioxide, typically deposited using atomic layer deposition. It is expected that defect states in the high-κ dielectric can influence its electrical properties.
Tranquillityite is silicate mineral with formula (Fe 2+) 8 Ti 3 Zr 2 Si 3 O 24. [1] It is mostly composed of iron, oxygen, silicon, zirconium and titanium with smaller fractions of yttrium and calcium. It is named after the Mare Tranquillitatis (Sea of Tranquility), the place on the Moon where the rock samples were found during the 1969 Apollo ...
Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" ( Zr O 2 ) and "yttria" ( Y 2 O 3 ), hence the name.
