Silicon Carbide

Silicon carbide is a compound of silicon and carbon. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics which are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light emitting diodes and detectors in early radios were first demonstrated around 1907, and nowadays silicon carbide is widely used in high-temperature/high-voltage semiconductor electronics.

Silicon Dioxide

Silicon dioxide (Silica) is an oxide of silicon. It is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. It is used primarily in the production of glass for windows, drinking glasses, beverage bottles, and many other uses. The majority of optical fibers for telecommunications are also made from silica. It is a primary raw material for many whiteware ceramics such as earthenware, stoneware, porcelain, as well as industrial Portland cement. It is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications. It is the primary component of diatomaceous earth which has many uses ranging from filtration to insect control. It is also the primary component of rice husk ash which is used, for example, in filtration and cement manufacturing. Thin films of silica grown on silicon wafers via thermal oxidation methods can be quite beneficial in microelectronics, where they act as electric insulators with high chemical stability. In electrical applications, it can protect the silicon, store charge, block current, and act as a controlled pathway to limit current flow. A silica-based aerogel was used in the Stardust spacecraft to collect extraterrestrial particles. It is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. In cosmetics, it is useful for its light-diffusing properties and natural absorbency. Colloidal silica is used as a wine and juice fining agent. In pharmaceutical products, silica aids powder flow when tablets are formed.

Silicone Spray Lubricant

Silicone Spray Lubricant provides superior lubrication on metal to non-metal contact surfaces. It creates a slippery, non-sticky, dry, and long lasting corrosion resistant film. It repels water, ink, grease and rust and displaces water. It helps to prevent rubber from cracking and drying. May be used on all surfaces except in areas to be painted.

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.

Silver Carbonate

Silver carbonate is a chemical compound. It is used as a reagent in organic synthesis such as the Koenigs-Knorr reaction. It is also employed to convert alkyl bromides into alcohols. It can be easily prepared by combining aqueous solutions of sodium carbonate and silver nitrate.

Properties Suppliers
Silver Chloride

Silver chloride is used to make photographic paper since it reacts with photons to form latent image and via photoreduction. The silver chloride electrode is a common reference electrode in electrochemistry. It has been used as an antidote for mercury poisoning, assisting in the elimination of mercury. It is used to create yellow, amber, and brown shades in stained glass manufacture. It is also used in bandages and wound healing products.
