Polysilicates are geochemically important compounds formed by the reaction of the acidic oxide SiO 2 (silica) and basic metal oxides. These compounds possess definite silicon oxo anions having covalent Si-O bonds but do not have the simple silicate ion SiO 44-.

Single chain polysilicates form when a number of [SiO 3] 2- units link together into long chains. In these structures each silicon has 2 terminal oxygens and 2 bridging oxygens. The charge density is -2 per silicon atom. Single chain polysilicates comprise part of the subclass inosilicates.

However, crocidolite and amosite are actually examples of inosilicates rather than phyllosilicates. They are a little bit different from the inosilicates that we saw before, however. Rather than containing single polysilicate chains, these materials contain double polysilicate ribbons.

2024年1月26日 · Interconnecting the nodes with linear, aliphatic α,ω-alkanediol linker molecules yields PolySilicate Porous Organic Polymers (PSiPOPs), a new type of ordered reticular material related to the well-known metal–organic and covalent organic frameworks (MOFs and COFs).

2023年2月16日 · Rheology additives of the WOLLATROP ® series are innovative rheology modifiers for aqueous systems based on ribbon polysilicates. Due to its needle-like morphology, this clay mineral shows unique properties such as very high external surface, high density of surface-active centers and low ion-exchange capacity.

2024年7月19日 · Sodium polysilicate is a common name for a group of compounds with the base elemental composition of sodium and a chain of silicon ions. It is typically insoluble when in solid form and may be described as water glass or liquid glass when in aqueous form.

Lithium polysilicate is an inorganic binder useful for coating, surface modification, and polymer reinforcement applications. Unlike polysilicates based on sodium or potassium ions, the lithium ions in lithium polysilicate permit a ratio of 4.8 of silica to lithium oxide.

Lithium Polysilicate is an inorganic binder useful in surface modification, coatings, and polymer reinforcement. Common applications include high performance zinc coatings, and marine/industrial applications where high pigment loading, and/or …

2001年7月3日 · Interlayer modification of a layered polysilicate kanemite was performed by silylation with mono-, di-, and trichloro (alkyl)silanes. The introduction of silyl groups into the interlayer region was confirmed by XRD, IR, 13 C NMR, and 29 Si NMR.

2021年10月13日 · Polysilicon, a high-purity form of silicon, is a key raw material in the solar photovoltaic (PV) supply chain. To produce solar modules, polysilicon is melted at high temperatures to form ingots, which are then sliced into wafers and processed into solar cells and solar modules.
