Magnesium Sulfide LAB GRADE 99%

Magnesium sulfide is colorless to brown crystal powder, which is sulfide of magnesium. It is of sodium chloride type structure and the chemical property is similar to other  ionic type sulfide compounds as sodium sulfide, barium sulfide and calcium sulfide. Magnesium metal and pure sulfur are the raw materials.  It dissolve in diluted hydrochloric acid, however MgS crystal react with water slowly.

Manganese Carbide Industrial Grade 99%

Manganese carbide is black crystal powder, which is metal carbide.  It is soft crystal solid or bright needle-like crystal. Mn3C is insoluble in concentrated sulfuric acid and nitric acid, how it can be decomposed by water or dilute acid to form manganese hydroxide, hydrogen and hydrocarbon. It burns in oxygen quickly. Mn3C tend to react with fluorine and chlorine. Manganese powder is the raw material.

Mercuric Chloride

Mercuric chloride is a laboratory reagent and a molecular compound. It is no longer used for medicinal purposes because it is highly toxic and superior treatments have become available. The main application of mercuric chloride is as a catalyst for the conversion of acetylene to vinyl chloride, the precursor to polyvinylchloride. It was used as a photographic intensifier to produce positive pictures in the collodion process.

Properties Suppliers
Mercuric Nitrate

Mercuric nitrate is a toxic colorless or white soluble crystalline mercury(II) salt of nitric acid. It was used to treat fur to make felt in a process called 'carroting'. It is an oxidizing agent. It is also used as an analytical reagent, in bronzing, as a nitrating agent, and in organic synthesis. It has antiseptic and miticidal properties; once used topically in the treatment of demodectic mange in dogs, but replaced by safer and more effective agents.

Melting Point:236℃ Boiling Point:322℃ Density: 6.109 UN 1634 6.1/PG 2

Applications

HgBr2 is for analytical reagent that test arsenic by Gutzeit method. It is also for medical industry.

Properties Suppliers
Mercury Chloride Industrial Grade 99%

Mercury chloride is white crystalline powder, which slightly volatilize at room temperature. It is a common mercury reagent. White liquid mercury is the raw material. It is soluble in water, ethyl alcohol, diethyl ether, methyl alcohol, acetone and ethyl acetate, however not in carbon disulfide and pyridine. Mercury(II) chloride is high toxic. It should refer to MSDS when handling.

Mercury Chloride

CAS No.:7487-94-7 EINECS No.: 231-299-8 Molecular Formula:HgCl2 Molecular Formula:271.50
Melting Point:277℃ Boiling Point:302℃ Density:5.44 UN 1624 6.1/PG 2

Applications

Mercury dichloride is raw material for producing mercury(I) chloride and other mercury salts. It is a kind of battery depolarizer. It uses as catalyst for producing polyvinyl chloride. However it uses as preservative in medicine and wood.

Mercury(II) chloride is mordant in pesticide, coating and dyeing. Amalgamation process before silver plating need it to improve binding force of silver coating and base metal.

Mercury bichloride is important reagent for analytical chemical. It is catalyst  for organic synthesis.

HgCl2 is raw material for metallic amalgam. For example when processing aluminum amalgam, dipping aluminum into mercury chloride solutions would compound with mercury on the surface to amalgam. The formed amalgam remove the oxide layer protection and activate aluminum.

Mercury Oxide Industrial Grade 99.9%

Mercury oxide is orange color powder, however it is red powder when compounding with trimercury dinitride. There is another name for red powder, Hydrargyri Oxydum Rubrum. HgO orange powder rarely dissolve in water, alcohol and acetone, however dissolve in dilute nitric acid or hydrochloric acid. Mercuric oxide uses mercury(I) nitrate, mercury or mercury mercury as raw material. But the red one needs mercury, potassium nitrate, alumen and so on.

Mercury Oxide

CAS No.:21908-53-2 EC No.:244-654-7 Molecular Formula:HgO Molecular Weight:216.59
