16871-71-9 Usage

Description

It has widespread applications including fast hardener for concrete, wood preservative, plaster enhancer, postscrubbing agent, mothproofing agent, catalyst for the production of polyester fibre, and ingredient in electrolytic bath for preparing zinc. Moreover, it may act as an active agent in mould-resistant emulsion paints.1 This chemical may also be used as an additive for hardening and polishing the concrete surface, such as a floor or wall.2 In addition, a pasty mixture prepared by mixing zinc fluosilicate with other chemicals shows a desirable function for cleaning stone, bricks, concrete, and other constructional material.3 Besides, the use of this compound in the froth-flotation process aids in effecting selection of valuable mineral.4

Chemical Properties

White crystals.Decomposes on heating; soluble in water.

General Description

A solid material, or the solid mixed with water. Insoluble in water and denser than water. Contact with the material may cause irritation to skin, eyes, and mucous membranes. ZINC SILICOFLUORIDE may be toxic by ingestion.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

ZINC SILICOFLUORIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

Inhalation of dust irritates nose and throat; excessive inhalation may cause severe pulmonary inflammation. Ingestion causes nausea, cramps, vomiting, shock, convulsions, cyanosis, and other symptoms of fluoride poisoning. Contact with eyes or skin causes irritation; skin ulcers may develop.

Fire Hazard

Special Hazards of Combustion Products: Toxic and irritating hydrogen fluoride and silicon tetrafluoride are formed in fires.

Safety Profile

Poison by ingestion and subcutaneous routes. When heated to decomposition it emits toxic fumes of F- and ZnO. See also ZINC COMPOUNDS.

Check Digit Verification of cas no

The CAS Registry Mumber 16871-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,7 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16871-71:
(7*1)+(6*6)+(5*8)+(4*7)+(3*1)+(2*7)+(1*1)=129
129 % 10 = 9
So 16871-71-9 is a valid CAS Registry Number.

Four novel linear trinuclear assemblies containing bridging triazole ligands. Crystal structure, magnetic, semiconducting and fluorescent properties

Liu, Bing,Xu, Ling,Guo, Guo-Cong,Huang, Jin-Shun

, p. 79 - 86 (2006)

Four homotrinuclear linear coordination compounds with bridging ligand of (m-phenol)-1,2,4-triazole, [Mn3(L)6(H2O)6](ClO4)6 (1), [Ni3(L)6(H2O)6](BF4)6·4DMF (2), [Cd3(L)6(H2O)6](ClO4)6· 2H2O·2DMF·2EtOH (3), [Zn3(L)8(H2O)4](BF4)4(SiF6)·2EtOH·12H2O (4), have been synthesized and structurally determined. The structures consist of three metal ions in linear arrangements, linked to each other by two pairs of three N1, N2 bridging triazole ligands. The negative value of J suggests that antiferromagnetic interaction exists in 1. Green fluorescence of 2 and 4 with emissions at 518 nm for 2 and 524 for 4 is possibly assigned to LMCT. The energy gaps of the compounds 2 and 4 are 1.82 and 1.97 eV, respectively, which suggests that the two materials behave as semiconductors.
