Mica By Vishnu Mineral Industries

P { margin-bottom: 0.21cm; } Enriched with a keen understanding of demands of our valuable customers, we are engaged in offering Mica Powder. This mineral is a group of a complex aluminosilicate minerals having a plate or sheet like structure with different physical properties and chemical compositions. Widely used in transistor and semi-conductors, communication devices, radio & television tubes and many other products, our offered Mica Powder is packed in moisture proof packaging so as to ensure their effectiveness for longer time. Features: Uniform dielectric constant low temperature coefficient Heat resistant Incombustible Other Details:It is mined in the form of "blocks" or rocks, which are then rifted to arrive at thin flexible natural mica splittings. Mica is a complex hydrous silicate of aluminium, containing potassium, magnesium, iron, sodium fluorine and/or lithium and also traces of several other elements. It is stable and completely inert to the action of water, acids (except hydro-fluoric and concentrated sulphuric) alkalies, conventional solvents, oils and is virtually unaffected by atmospheric action. It is transparent, optically flat, easily splittable into thin films along its cleavage, colourless in thin sheets, resilient and incompressible.Mica has a high dielectric strength to prevent current from flowing across it at moderate voltages. Properties: Mica has the unique combination of great dielectric strength, uniform dielectric constant and capacitance stability, low power loss (high Q factor), high electrical resistivity and low temperature coefficient and capacitance. It is fire proof, infusable, incombustible and non-flammable and can resist temperatures of 600oC to 900oC (1112oF to 1652oF) depending on the type of mica. It has low heat conductivity, excellent thermal stability and may be exposed to high temperatures without noticeable effect. Mica is relatively soft and can be hand cut, machined or die-punched. It is flexible, elastic and tough, having high tensile strength. Uses Mica is invaluable in the electrical industry because of its unique combination of physical, chemical and thermal properties. * Cut Mica    Plates for    Mica    Capacitors * Radiation    Insulation * Transistor and    Semi-Conductors * Electrical    Heating    Appliances * Silvered    Mica Plates * Radiation    Pyrometers      and Thermal    Regulators * Communication    Devices * Flat irons * Mica    Capacitors * Resistance and    Potentiometers    Cards * Accoustics    Aparatus,    Detonators,    Radiophone,    Gramophone,    Sound Boxes,    Head Phones,    LoudSpeakers * Kettle * Radio &    Television    Tubes * Primary and    Secondary    Insulation * Steam Boilers * Toasters * Guided * Bushing and    Tubes * Quarter Wave    Plates for Optical    Instruments * Band   Heaters * Microwave    Tube    Windows * Televisions * Marker Dials for    Navigation    compasses * Strip and    Finned    Heaters * Target and    Mosaic    Mica for    Telecasting    Industry * Geiger Counter    for Radio * Goggles * Soldering    Irons *  High Speed    Aircraft    Randoms    and    Canopies * High Tension    Coil of Radars * Diaphragms for    Oxygen Breathing    Equipment * Incandescent    Lamps,    Fuse    Plugs,    Fuse Boxes,    Electric      Lamp    Sockets,    Lighting    Apparatus,    Induction    Coils, Grid    Rheostats * Jet Engines * Telephone * Windows for    Anthracite Gas or    Petromax Lamps    and Kerosene    Stoves, Isinglass,    Furnace, Peepholes,    Heat Screens,    Metalurgical    Furnaces and Kilns,    Canopies, Shields,    smoke Helmets,    Diver Helmets, Gas    Masks, etc. * Neon-Lights * Interlayer    Insulation    for    Transformer    Coils * High Voltage    Lamps     Pressed mica sheets are often used in place of glass in greenhouses. Mica is often found in mineral cosmetics. Some brands of toothpaste include powdered white mica. This acts as a mild abrasive to aid polishing of the tooth surface, and also adds a cosmetically-pleasing glittery shimmer to the paste. The shimmer from mica is also used in makeup, as it gives a translucent "glow" to the skin or helps to mask imperfections. Mica is used in the production of pearlescent pigments. Many metallic looking pigments are composed of a substrate of mica coated with another mineral, usually TiO2. The resultant pigment produces a reflective color depending on the thickness of the coating. These products are used to produce automobile paint, shimmery plastic containers, high quality inks used in advertising and security applications. Another use of mica is in the production of ultraflat thin film surfaces (e.g. gold surfaces) using mica as substrate. Muscovite mica is the most common substrate for sample preparation for the atomic force microscope.
