Nano Silver Hydrogen Peroxide (Ag2H2O2, Purity: 99.9%, Diameter: <100nm) Quick inquiry Where to buy Suppliers range | Silver oxide is a three-dimensional covalent polymer that is insoluble in most solvents. It is slightly soluble in water to form hydrolysis products. It is soluble in the acid that generates soluble silver salt, and it can also be dissolved in coordination with ammonia water, ammonium carbonate, potassium cyanide and potassium cyanide solution. Silver oxide reacts with alkali metal chloride solution to precipitate silver chloride and generate alkali metal hydroxide solution. After its ammonia solution is placed for a long time, sometimes strong explosive black crystals will be precipitated, which may be silver nitride (Ag3N) or silver nitrite (Ag2NH). Like many silver compounds, silver oxide is sensitive to light and will decompose above 280°C. Uses: ·Electrode material ·Used as a weak oxidant in organic synthesis ·Converts organic bromides and chlorides into alcohols at low temperature and in the presence of water vapor, and is used in combination with methyl iodide as a methylation reagent for sugar methylation analysis and Hoffmann elimination reactions.

Rhodium nanoparticles entrapped in aluminum hydroxide matrix preparation Quick inquiry Where to buy Suppliers range | Rhodium nanoparticles entrapped in aluminum hydroxide matrix preparation. Uses: At ordinary temperatures rhodium is stable in air. When heated above 600°C, it oxidizes to Rh2O3, forming a dark oxide coating on its surface. The gray crystalline sesquioxide has a corundom-like crystal structure. The sesquioxide, Rh2O3 , decomposes back to its elements when heated above 1,100°C. However, on further heating the metal starts to lose its weight similar to platinum, probably due to loss of its volatile oxide RhO2 dissolved in the metal. The molten metal readily absorbs gaseous oxygen. The metal in powder form absorbs hydrogen when heated. When heated with carbon monoxide under pressure rhodium forms carbonyl, Rh4(CO)12. The metal combines with halogens at elevated temperatures. When heated with fluorine at 500 to 600°C, it forms a trifluoride, RhF3, a red rhombohedral crystalline powder insoluble in water, dilute acids, or alkalis. Also, a blue tetrafluoride, RhF4, is formed as a minor product. When heated with chlorine gas above 250°C, the brown-red trichloride, RhCl3, forms. It is hygroscopic, decomposing at 450°C. Rhodium is attacked by fused caustic soda or caustic potash. Also, fused sodium or potassium cyanide and sodium bisulfate attack the metal. Molecular formula: Rh/AlO(OH). | |

Tin Quick inquiry Where to buy Suppliers range | Tin. Uses: At ordinary temperatures tin is stable in air. It actually forms a very thin protective oxide film. In powder form, and especially in the presence of moisture, it oxidizes. When heated with oxygen it forms tin(IV) oxide, SnO2.Tin reacts with all halogens forming their halides. Reaction with fluorine is slow at ordinary temperatures; however, chlorine, bromine and iodine readily react with the metal. Tin is attacked by concentrated acids. With dilute acids the reaction may be slow or very slow. The metal readily reacts with hot concentrated hydrochloric acid and aqua regia but slowly with cold dilute hydrochloric acid. The reaction also is slow with hot dilute sulfuric acid, which dissolves the metal, particularly in the presence of an oxidizing agent. The reaction with nitric acid is generally slow. Hot concentrated acid converts the metal to an insoluble hydrated tin(IV) oxide. The reaction is rapid with moist sulfur dioxide or sulfurous acid, chlorosulfonic, and pyrosulfuric acids. Organic acids such as, acetic, oxalic, and citric acids react slowly with the metal, particularly in the presence of air or an oxidizing agent. Strong alkaline solutions of caustic soda or caustic potash dissolve tin forming the stannate, Na2SnO3, or K2SnO3. The metal is stable in dilute solutions of ammonia or sodium carbonate. Tin dissolves in solutions of oxidizing salts such as potassium chlorate or potassium persulfate. The metal does not react with neutral salts in aqueous solutions. In air, tin reacts slowly with neutral salts. The metal does not combine directly with hydrogen, nitrogen or ammonia gas. Group: Nanoparticles & Nanopowders.
