AAA Molybdenum Products Molybdenum Trioxide, 99.90% is a fine yellow crystalline powder that develops a bluish coloration as a result of superficial surface reduction. The product is also known as Molybdenum Trioxide, Molybdic Acid Anhydride, and Molybdenum (VI) Oxide. It is very slightly soluble in water and very soluble in excess alkali with the formation of molybdates. It is a high purity compound.

AAA Molybdenum Products Ammonium Heptamolybdate, ACS Reagent Grade is a white, crystalline powder, soluble in water. It is a high purity compound and can be used in gravimetric precipitation analysis, particularly Phosphate, Silicate, Arsenate, and Lead; therefore, ACS Reagent specifications are particularly stringent in respect to these trace anions. When heated, Ammonium Heptamolybdate will begin to release its waters-of-hydration (above 90°C) and decompose (above 190°C) into Ammonia and other Molybdate derivatives. Ammonium Heptamolybdate is distinguished by a very low trace impurity concentration and by the highest water solubility of any ammonium molybdate: 63.5 g/100 cm3 at 25°C.

AAA Molybdenum Products Lead Molybdate is a very fine white to light violet, photosensitive crystalline powder. It is a high purity compound. The mineral Lead Molybdate is known as Wulfenite. The product is also known as Lead Molybdenum Oxide. It has a melting point of 1065°C (1949°F) and it begins to volatilize, without decomposition, above 1050°C. Lead Molybdate is insoluble in water and decomposed by sulfuric acid. It is highly soluble in nitric acid, and soluble in hydrochloric acid and sodium hydroxide solutions.

AAA Molybdenum Products Molybdenum Trioxide, 99.95% is a fine yellow crystalline powder that develops a bluish coloration as a result of superficial surface reduction. The product is also known as Molybdenum Trioxide, Molybdic Acid Anhydride, and Molybdenum (VI) Oxide. It is very slightly soluble in water and very soluble in excess alkali with the formation of molybdates. It is a high purity compound.

AAA Molybdenum Products Molybdenum Disulfide is a shiny silver-gray, fine powder commonly described as slippery. It is insoluble in water. It is a high purity compound. The most common form of Molybdenum on Earth is Molybdenum Disulfide, also known as Molybdenite. Molybdenum Disulfide is used as a solid lubricant where conventional lubricants would normally decompose or burn off. It is ideal for high temperature environments.

AAA Molybdenum Products Sodium Perrhenate is a white crystalline powder having a high solubility in water. It is rather deliquescent and can be melted at about 400°C. The specific gravity is 5.24-5.39. It is a high purity compound.

AAA Molybdenum Products Ammonium Perrhenate is a white crystalline powder soluble in water and aqueous alkalis. The specific gravity is 7.53 gm/cc. It decomposes beginning at about 300°C, and completely above 400°C.

AAA Molybdenum Products Molybdenum Trioxide, ACS Reagent Grade is a fine yellow crystalline powder that develops a bluish coloration as a result of superficial surface reduction. The product is also known as Molybdenum Trioxide, Molybdic Acid Anhydride, and Molybdenum (VI) Oxide. It is very slightly soluble in water and very soluble in excess alkali with the formation of molybdates. It is a high purity compound.

AAA Molybdenum Products Molybdenum Disilicide is a dark gray powder.It is also referred to as Molybdenum Disilicide. The theoretical content is 36.9% Si and 63.1% Mo. It has a particle density of 5.7-6.0 g/cc, and an apparent density (Scott Volometer) of 15-25 g/in3. The melting point is 1870°C. However, it begins to decompose before melting. Molybdenum Silicide is best known for it's outstanding oxidation resistance at high temperatures up to about 1700°C. At temperatures above 1700°C, rapid oxidation occurs. It is also resistant to most inorganic acids, including aqua regia, and aqueous solutions of alkalies. It is easily soluble in molten alkalies.

AAA Molybdenum Products Molybdenum Metal Powder has a silvery-gray appearance. The melting point is about 2626°C. It is a high purity compound.

AAA Molybdenum Products Molybdenum Trioxide, Pure Grade (POC) is a fine yellow crystalline powder that develops a bluish coloration as a result of superficial surface reduction. The product is also known as Molybdenum Trioxide, Molybdic Acid Anhydride, and Molybdenum (VI) Oxide. The Pure Grade is also known as Pure Oxide Calcined (POC). It is very slightly soluble in water and very soluble in excess alkali with the formation of molybdates. It is a high purity compound.

AAA Molybdenum Products Perrhenic Acid Solution (40 - 60% Re) is a colorless to a straw colored solution. Any concentration less than 60% Re is achievable, but typical Perrhenic Acid Solutions contain 40-60% Re (as Perrhenic Acid, HReO4). The specific gravity will usually range from 1.70-2.80 g/cc depending on the concentration of Re. Perrhenic Acid is a strong acid but it is very stable and shows little oxidizing power. On concentration to 45% Re and above, the solution becomes increasingly straw colored and more viscous.
