Suppliers
Lead Nitrate

Lead Nitrate is a granular white crystal powder with the chemical formula Pb (NO3)2. It is produced by dissolving metallic lead in aqueous nitric acid. Lead nitrate is the raw material for the pigments for lead paints, lead compounds, nylon fiber stabilizer, textile mordant, and leather tanning agent.

Suppliers
Ascorbic Acid

Ascorbic acid is a naturally occurring organic compound with antioxidant properties. Ascorbic acid and its sodium, potassium, and calcium salts are commonly used as antioxidant food additives. In plastic manufacturing, ascorbic acid can be used to assemble molecular chains more quickly and with less waste than traditional synthesis methods. It is a cofactor in tyrosine oxidation. It is easily oxidized and so is used as a reductant in photographic developer solutions and as a preservative. In fluorescence microscopy and related fluorescence-based techniques, ascorbic acid can be used as an antioxidant to increase fluorescent signal and chemically retard dye photobleaching. It is also commonly used to remove dissolved metal stains, such as iron, from fiberglass swimming pool surfaces.

Suppliers
Sodium Nitrite

Sodium Nitrite is a water-soluble, hygroscopic white or slightly yellowish solid. The chemical formula of sodium nitrite is NaNO2 with molecular weight 68.9953 g/mol. The major sodium nitrite uses are as a food additive, precursor to pharmaceuticals, diazo dyes and pesticides.

Suppliers
Ammonium Dichromate

Ammonium Dichromate is an inorganic compound. It is a salt consisting of ammonium ions and dichromate ions. It has been used in pyrotechnics and in the early days of photography as well as in lithography, as a source of pure nitrogen in the laboratory, and as a catalyst. Ammonium Dichromate is also used as a mordant for dyeing pigments, in the manufacturing of alizarin, chrome alum, leather tanning and oil purification. Photosensitive films containing PVA, ammonium dichromate, and a phosphor are spin-coated as aqueous slurries in the production of the phosphor raster of television screens and other devices. The ammonium dichromate acts as the photoactive site.

Metol

Metol is a developing agent used in black & white photographic developers. In its pure form, it is a solid rather light-sensitive chemical which is the half sulfate (hemisulfate) salt of N-methyl-p-aminophenol. It is also used as hair dye intermediate.

Erbium

Erbium is a rare earth element which is associated with several other rare elements in the mineral gadolinite from Ytterby in Sweden. It is commonly used as a photographic filter, and because of its resilience it is useful as a metallurgical additive. It is also used in nuclear technology in neutron-absorbing control rods. When added to vanadium as an alloy, erbium lowers hardness and improves work ability. Erbium oxide has a pink color, and is sometimes used as a colorant for glass, cubic zirconia and porcelain. The glass is then often used in sunglasses and cheap jewelry. Erbium-doped optical silica-glass fibers are the active element in erbium-doped fiber amplifiers, which are widely used in optical communications. A large variety of medical applications utilize erbium ion's 2940 nm emission, which is highly absorbed in water. Such shallow tissue deposition of laser energy is necessary for laser surgery, and the efficient production of steam for laser enamel ablation in dentistry.

Silver

Silver is a transition metal. It has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. The metal occurs naturally in its pure, free form, as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. It has long been valued as a precious metal, and it is used to make ornaments, jewelry, high-value tableware, utensils, and currency coins. Today, silver metal is also used in electrical contacts and conductors, in mirrors and in catalysis of chemical reactions. Its compounds are used in photographic film, and dilute silver nitrate solutions and other silver compounds are used as disinfectants and microbiocides. While many medical antimicrobial uses of silver have been supplanted by antibiotics, further research into clinical potential continues.
