Chemical Properties
Lithium chromate is a yellow crystalline powder.
Uses
Lithium Chromate is used in preparation method method of permeable crystalline cement-based waterproof coating by using maifanstone composite high water-absorbing resin and its application in building.
Preparation
According to the following equations, Li2CrO4 is formed on boiling a solution of (NH4)2Cr2O7 with LiOH.
General Description
A yellow crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Lithium chromate is used as a corrosion inhibitor and in the manufacture of other chemicals.
Air & Water Reactions
Deliquescent. Water soluble
Reactivity Profile
Lithium chromate is an oxidizing agent. Can oxidize combustibles [USCG, 1999]. Combining the chromate with zirconium can be explosive given the right proportions of reactants, [Z. Anorg., 1930, 191, 113].
Health Hazard
INHALATION: Corrosive to skin and mucous membranes causing dermatitis and slow healing ulcers. EYES: Conjunctivitis and lacrimation. INGESTION: Violent gastroenteritis, peripheral vascular collapse, vertigo, muscle cramps, coma, hemorrhagic diathesis, fever, liver damage and renal failure.
Potential Exposure
Used as a corrosion inhibitor, heat
transfer agent; and oxidizing agent in leather and metal finishing. Also used in photography, wood preservatives; batteries, safety matches, and cement
First aid
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.
