Fine, bright-scarlet powder.Insoluble in water and alcohol.
Cinnabar, HgS, cherry red crystal to 5 mm among snow white rhombic dolomite, CaMg(CO3)2. Wanshan mine, Tongren Pref., Guizhou prov., China.
??
Mercury(II) sulfide is used in paint, sealing wax and preservatives.??
cinnabar: A bright red mineralform of mercury(II) sulphide, HgS,crystallizing in the hexagonal system;the principal ore of mercury. Itis deposited in veins and impregnationsnear recent volcanic rocks andhot springs. The chief sources includeSpain, Italy, and Yugoslavia.??? ?? ??
Readily oxidized as to be pyrophoric in air [Bretherick 1979. p. 120].?? ???
Inorganic reducing agents, such as MERCURY(II) SULFIDE, react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive.???
Highly toxic by ingestion, inhalation, and skin absorption.????
Acute poisoning can result from inhaling dust concentrations of 1.2-8.5 mg/m 3 in air; symptoms include pain and tightness in chest, coughing, and difficulty in breathing. If ingested, toxicity depends on release of t he Hg ++ ion; chronic mercury poisoning can cause kidney, mental, and nervous disturbances. Dust irritates eyes and frequently causes allergic dermatitis; absorption through skin can cause systemic poisoning.?? ???, ?? ?? ?? ? ???
