A nonmetalic element analogous to carbon. It always occurs combined in nature, and is artificially obtained in the free state, usually as a dark brown amorphous powder, or as a dark crystalline substance with a meetallic luster. Its oxide is silica, or common quartz, and in this form, or as silicates, it is, next to oxygen, the most abundant element of the earth's crust. Silicon is characteristically the element of the mineral kingdom, as carbon is of the organic world. Symbol Si. Atomic weight 28. Called also silicium.
a mineral and element necessary for bodily functions and growth. Helps build strong bones, teeth and nails, and stimulates calcium absorption. No RDA for silicon has been established. The compound of silicon and oxygen is silica -- see silica. No RDA has been established. This nutrient is essential for some higher animals but has not been proven to be necessary for humans. You can find more information and obtain silicon in our BioArmor(tm) and Bone Essence(tm).
A grey-black non-metallic semiconducting element that occurs in nature as silica and silicates, present in whole grains and in organ meats.
A chemical element, atomic number 14, semimetallic in nature, dark gray, an excellent semiconductor material. A common constituent of sand and quartz (as the oxide). Crystallizes in face-centered cubic lattice like a diamond. The most common semiconductor material used in making photovoltaic devices.
Silicon is a common mineral that is required, along with calcium, for the development and maintenance of strong bones. It also plays an important role in the formation of collagen and connective tissues, as well as the hair, skin and nails.
A trace mineral found naturally in soil and present in skeletal structures such as bones and teeth.
A non-essential mineral. Tissues such as arteries, tendons, skin, connective tissue, cornea and sclera (white of the eye) contain relatively large amounts of silicon. Collagen, the protein glue that holds us together, contains silicon in silanolate form. While vitamin C functions only as a catalyst in the formation of collagen, silicon is actually a structural part of collagen. Silicon containing substances are found in all cartilage and in the material binding cells together. Silicon may be needed for proper bone structure and growth.
This nutrient is necessary for collagen formation in cartilage, bones, and other connective tissues.
Silicon is one of the principal deoxidizers with the amount used dependent on the deoxidization practice. It slightly increases the strength of ferrite without a serious loss of ductility. In larger quantities, it aids the resistance to scaling up to 500°F in air and decreases magnetic hysteresis loss.
Silicon serves as a principal deoxidizer in steel. Its content in the steel is dependent upon the steel type. Killed steel has the highest percentage of silicon, upwards of 0.60 percent.
Used as a deoxidiser in steelmaking, and also as a strengthening agent. An alloy addition in spring steels (~1.5%), in heat resisting steel (1.5 - 3.5%) and in steel sheet for transformer cores (3%). It is important to be aware silicon can influence the control of post-galvanising, especially in combination with phosphorous.
A material that is added most often to Caulking to aid in durability
A caulk that you cannot paint. A caulk with plenty of substitutes. A caulk with limited applications. A caulk that's tough to remove. A caulk that never hardens completely.
Tubing material used in rig making
