Lithium Ceramics And Glass

Calcium and aluminum soaps as substitutes for stearates in greases.

Lithium ceramics and glass. They consist of a large volume fraction of up to 70 fine rod like entangled li 2 si 2 o 5 crystals and a minor amount of lithium orthophosphate li 3 po 4 crystals that are randomly oriented and uniformly dispersed in the glassy matrix. Spodumene is a lithium aluminum silicate and already contains silicon oxide and aluminum oxide which is a major component in glass. Substitution for lithium compounds is possible in batteries ceramics greases and manufactured glass. And sodic and potassic fluxes in ceramics and glass manufacture.

The key raw material lithium is found not only in lithiumion batteries. However lithium exploration projects in argentina aren t exclusively tied to batteries. Die rasant steigende nachfrage nach lithium lässt den rohstoffpreis in die höhe schnellen. One example is a li 2 s p 2 s 5 glass or glass ceramic the maximum conductivity for which occurs at 20 30 p 2 s 5 depending on the degree of crystallization the conductivities of some li 2 s p 2 s 5 electrolytes are shown in fig.

Lithium disilicate glass ceramics are derived from the sio 2 li 2 o system that was first investigated by stookey at corning glass works in the 1950s. In contrast other lithium compounds may be quite refractory. The dominant crystalline phase of the las glass ceramics hq s s has a strong negative coefficient of thermal expansion cte keatite solid solution as still a negative cte but much higher than hq s. Lithium aluminosilicate glass ceramics have found widespread commercial success in areas such as consumer products telescope mirrors fireplace windows etc.

Examples are calcium magnesium mercury and zinc as anode material in primary batteries. It is also a component of ceran cooktop panels and other products made of glass ceramic that owe to it their special characteristics. The fast growing demand for lithium is causing the commodity price to climb. The best known application is the manufacture of glass ceramic cooktops where no thermal expansion and thermal resistance is essential.

Lithium glass and lithium ceramics colour your world. Ceramics and glass have played a major role in day to day life for decades. Lithium oxide is widely used as a flux for processing silica reducing the melting point and viscosity of the material and leading to glazes with improved physical properties including low coefficients of thermal expansion. Lithium zirconate and lithium aluminum spinel are examples.

Lithium carbonate is a very strong flux also true of lithium fluoride. Glass ceramic from the las system is a mechanically strong material and can sustain repeated and quick temperature changes up to 800 1000 c. Lithium market price and lithium uses. Sulfide compounds in crystalline amorphous and partially crystalline forms have been used as lithium ion conductors.

Worldwide this is one of the largest use for lithium compounds.
