Cadmium sulfide Chemical Properties,Uses,Production

Chemical Properties

Cadmium sulfide is an odorless, crystalline, lemon yellow to orange solid.

Physical properties

Yellow to orange crystal; occurs as two polymorphs, hexagonal alpha form and cubic beta form; exhibits stable wurtzite structure at lower temperature, and zinc blende type structure at higher temperatures; the beta form converts to alpha form when heated at 750°C in sulfur atmosphere; sublimes at 980°C; practically insoluble in water (1.3 mg/L at 20°C); Ksp 3.6x10-29; dissolves in dilute mineral acids on heating or concentrated acids at ordinary temperatures (decomposes with liberation of H2S).

Occurrence

Cadmium sulfide occurs in nature as the mineral greenoktite. The compound is widely used in pigments for paints, baking enamels, ceramics and plastics. It imparts bright yellow to maroon, with strong retention of color and resistance to alkalis. It also is used in inks, phosphors, and fluorescent screens. Other applications of this compound are in photovoltaic and solar cells (for converting solar energy to electrical energy), photoconductors (in xerography), thin film transistors and diodes, rectifiers, scintillation counters, pyrotechnics, and smoke detectors.

History

The discovery of cadmium sulphide is linked to that of the element cadmium. In 1817, the German chemist Friedrich Stromeyer, while examining samples of zinc carbonate, observed that upon heating, they turned yellow rather than the white colour expected for pure zinc oxide. Through further investigation, he isolated a new metal oxide and identified the presence of a previously unknown element, cadmium, associated with the zinc compounds.

Uses

Used in the production of solar cells where it is used as a buffer layer in the manufacture of CIGS (Copper -Indium-Gallium-Selenide) solar cells

Uses

As a pigment being fast to light and not affected by H2S; color for soaps; coloring glass yellow; coloring textiles, paper, rubber; in printing inks, ceramic glazes, fireworks; in phosphors and fluorescent screens; in scintillation counters, semiconductors, photoconductors.

Uses

cadmium sulfide is used as a colorant for paints and rubber; cadmium acetate is used in the production of craftware.

Production Methods

Cadmium sulfide may be prepared by the reaction between hydrogen sulfide and cadmiumvapor at 800 Cor by heating a mixture of cadmium or cadmium oxide with sulfur.

Preparation

Cadmium sulfide may be prepared by precipitation from an aqueous solution of its soluble salts such as cadmium chloride or cadmium nitrate by passing hydrogen sulfide. The reactions may be carried out in acidic, neutral or alkaline solutions using various cadmium salts to obtain different crystal modifications as shown in the table below.
1306-23-6 synthesis
Cadmium sulfide also may be obtained by treatment of sodium or other alkali metal sulfide solution with that of a soluble cadmium salt. The compound also may be prepared by heating a mixture of cadmium or its oxide with sulfur at 800°C; or by the reaction of H2S with cadmium vapor at 800°C.

Definition

Greenockite: a mineral form of cadmium sulphide, CdS.
A native cadmium sulfide containing 77.7% cadmium.
Ore of cadmium.

General Description

Natural occurrence: hawleyite (structural type of sphalerite) and greenockite (structural type of wurtzite)

Hazard

A confirmed carcinogen, highly toxic. See cadmium.

reaction suitability

reagent type: catalyst
core: cadmium

Safety Profile

Confirmed human carcinogen with experimental carcinogenic and tumorigenic data. Moderately toxic by ingestion and inhalation. Human mutation data reported. When heated to decomposition it emits very toxic fumes of Cd and SOx. See also CADMIUM COMPOUNDS and SULFIDES

Potential Exposure

Used in pigments; as an active ingredient in dandruff shampoos; making photoconductors, solar cells, and other electronic components.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for atleast 15 min, occasionally lifting upper and lower lids.Seek medical attention immediately. If this chemicalcontacts the skin, remove contaminated clothing and washimmediately with soap and water. Seek medical attentionimmediately. If this chemical has been inhaled, removefrom exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantitiesof water and induce vomiting. Do not make an unconsciousperson vomit. Medical observation is recommended for24-48 h after breathing overexposure, as pulmonary edemamay be delayed. As first aid for pulmonary edema, a doctoror authorized paramedic may consider administering a corticosteroid spray.Note to physician: In case of fume inhalation, treat pulmonary edema. Give prednisone or other corticosteroid orallyto reduce tissue response to fume. Positive-pressureventilation may be necessary. Treat metal fume fever withbed rest, analgesics, and antipyretics. The symptoms ofmetal fume fever may be delayed for 4-12 h followingexposure: it may last less than 36 h.Note to physician: For severe poisoning do not useBAL [British Anti-Lewisite, dimercaprol, dithiopropanol(C3H8OS2)] as it is contraindicated or ineffective inpoisoning from cadmium.

Solubility in water

Cadmium sulfide is soluble in water, with a solubility of 13×10-5 g/100 ml H2O (18℃). CdS is soluble in acid.

storage

Color Code—Blue: Health Hazard: Store in asecure poison location. Prior to working with Cadmium sulfide, you should be trained on its proper handling and storage. A regulated, marked area should be established wherethis chemical is handled, used, or stored in compliance withOSHA Standard 1910.1045. Store in tightly closed containers in a cool, dark, well-ventilated area away from oxidizersand metals, strong acids, water or moisture, and otherincompatible materials listed above.

Shipping

UN2570 Cadmium compounds, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Structure and conformation

Cadmium sulfide takes two types of structure, zinc blend and wurtzite structures.
Cubic system that has a zinc-blend structure, with a lattice constant of a=0.582 nm and Cd– S=0.252 nm.
Hexagonal system that has a wurtzite structure with lattice constants of a=0.4136 nm, c=0.6713 nm and c/a=1.624, Cd–S=0.252 nm.

Incompatibilities

Contact with water or moisture releases poisonous hydrogen sulfide gas. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause

Waste Disposal

Use a licensed professional waste disposal service to dispose of this material. All federal, state, and local environmental regulations must be observed. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposa
