Chemical Properties

Description	Vanadium pentoxide is a yellow to red colour solid and is odourless. Vanadium pentoxide dust is the particulate form of a non-combustible, odourless, yellow-orange or dark grey crystalline solid. On decomposition by heating, vanadium pentoxide produces toxic fumes. Vanadium is widely distributed in the Earth’s crust in a wide range of minerals and in fossil fuels. Vanadium pentoxide, the major commercial product of vanadium, is mainly used in the production of alloys with iron and aluminium. It is also used as an oxidation catalyst in the chemical industry and in a variety of minor applications. less more

Hazard Information

General Description

A yellow to red crystalline powder. Slightly soluble in water and denser than water. Contact may cause severe irritation to skin, eyes, and mucous membranes. May be toxic by ingestion, inhalation and skin absorption.

Reactivity Profile

VANADIUM PENTOXIDE(1314-62-1) is acidic in many reactions. Hence, soluble in bases. [Kirk-Othmer]. Can react with ClF3, Li, peroxyformic acid and (Ca+S+H2O). Also reacts with strong acids.

Air & Water Reactions

Slightly soluble in water.

Health Hazard

Probable oral lethal dose for humans is between 5 and 50 mg/kg or between 7 drops and 1 teaspoonful for a 70 kg (150 lb.) person. Toxicity is about the same magnitude as pentavalent arsenic. A person with chronic respiratory disease is at greater risk when exposed to this substance.

Potential Exposure

(dust); Suspected reprotoxic hazard, Suspected of causing genetic defects, Primary irritant (w/o allergic reaction), (fume) Possible risk of forming tumors, Vanadium pentoxide is an industrial catalyst in oxidation reactions; is used in glass and ceramic glazes; is a steel additive; and is used in welding electrode coatings.

Fire Hazard

Container may explode in heat of fire. When heated to decomposition, VANADIUM PENTOXIDE emits acrid smoke and fumes of vanadium oxides. Material is not flammable but VANADIUM PENTOXIDE may increase the intensity of the fire when in contact with combustible materials. Avoid chlorine trifluoride; lithium; peroxyformic acid; and calcium, sulfur, water complexes. Hazardous polymerization may not occur.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

The compound is toxic by ingestion, inhalation, and contact. Inhalation can cause asthma, cough, dyspnea, and bronchial constriction. Ingestion can cause gastrointestinal tract disturbances. Other toxic symptoms are skin pallor, greenish-black tongue, and papular skin rash (Lewis, R.J. (Sr) 1996. Sax’s Dangerous Properties of Industrial Materials, 9thed. New York: Van Nostrand Reinhold).
The oral LD₅₀ for V₂O₅ dust in rats is 10 mg/kg and the inhalation LCLO in rats is 70 mg/m³/2hr.

Carcinogenicity

Vanadium pentoxide was not mutagenic in Salmonella strains and did not increase the frequency of micronucleated erythrocytes in mice.9 In other studies vanadium compounds have produced clear evidence of aneuploidy in somatic cells after exposure by several different routes.

Questions And Answer

Physical properties
Brown-yellow orthorhombic crystals; density 3.35 g/cm3; melts at 670°C; decomposes at 1,800°C; slightly soluble in water, 0.8g/100 mL at 20°C; soluble in concentrated acids forming an orange-yellow solution; soluble in alkalies forming vanadates. ;
Uses
Vanadium(V) oxide is the oxide form of vanadium. As an important vanadium compound, it is used as the major precursor to alloys of vanadium and is widely used as industrial catalyst. It can be used for the production of ferrovanadium and sulfuric acid. It can also catalyze the oxidation reaction of some anhydrides. It can also be used as a detector material in bolometer arrays for thermal imaging because of its thermal resistance. Vanadium(V) oxide is also a kind of highly selective and stable ethanol sensor materials. Moreover, the microspheres of vanadium(V) oxide formed during the synthesis of vanadium(V) oxide nanorods in a mediated polyol process exhibit excellent electrochemical properties when used as the cathode material in a lithium-ion battery.
Other applications are in making yellow glass; as a depolarizer; as a developer in photography; inhibiting UV transmission in glass;and coloring ceram; as a mordant for dyeing and printing fabrics. ;
Preparation
Vanadium pentoxide is an intermediate in recovering vanadium from minerals (See Vanadium). Sodium polyvanadate, obtained as a red cake in one of the steps in extracting vanadium from its ores is calcined at 700°C in air to form a melt of vanadium pentoxide. Pentoxide is prepared in purified form by dissolving red cake in sodium carbonate solution followed by addition of an aqueous solution of ammonia and ammonium chloride. Ammonium metavanadate is precipitated which on decomposition at 320 to 430°C forms vanadium pentoxide. ;
