CAS 7439-97-6 99%purity Mercury
Mercury, the chemical symbol Hg, also known as mercury, is a very special metal. It has an extremely low melting point of -38.87 °C, and is the only metal that is liquid at room temperature and flows easily, with a silver bead- like appearance and a specific gravity of 13.595. Due to its unique properties, the vapor specific gravity of mercury is also relatively high at 6.9. The name mercury comes from the Latin word meaning "liquid silver". In the chemical industry, mercury is used as a feedstock in the production of mercury compounds or as a catalyst in reactions such as the electrolysis of salt to chlorine and caustic soda. Mercury is also used to extract precious metals such as gold and silver, as well as in gold plating and distillation processes. In dentistry, amalgam is often used to fill caries. In the nuclear industry, mercury is even used as a coolant in plutonium reactors, reflecting its special use in high-tech fields. Mercury has a long history of use and is versatile. In the Middle AgesalchemyNeutral withbrimstone, salt is called alchemyThe Sacred Three Elements。 Application field The most common applications for mercury are in the manufacture of industrial chemicals and in electronic or electrical products. Mercury is also used in thermometers, especially in thermometers that measure high temperatures. More and more gaseous mercury is still used in the manufacture of fluorescent lamps, while many other applications have been phased out due to health and safety concerns and replaced by the less toxic but much more expensive Galinstan alloy. In addition to this, mercury is used for: 1. It can decompose gold from its minerals, so it is often used in gold mines. 2. It is used to make barometers and diffusion pumps and other instruments. 3. Gaseous mercury is used in mercury vapor lamps. 4. It is used to manufacture liquid mirror telescopes. A telescope that rotates the liquid into a parabolic shape and uses it as a primary mirror for astronomical observations is one-third of the price of an ordinary telescope. 5. Mercury switches, pesticides, processes for the production of chlorine and potassium hydroxide, preservatives, acting as electrodes, batteries and catalysts in some electrolysis equipment. Storage method 1. Store in a cool and ventilated warehouse. 2. Keep away from fire and heat sources. The storage temperature should not exceed 30°C. It should be stored separately from flammable (combustible) materials and acids, and should not be mixed. The storage area should be equipped with emergency response equipment for spills and suitable containment materials.

100G QSFP28 LR4
FiberHTT 100G QSFP28 LR4 integrates four transmitter and receivers into one module. In the transmitter side, the four lanes of optical data channels are optically multiplexed by the integrated optical multiplexer. In the receive side, the four lanes of optical data channels are optically de- multiplexed by the integrated optical de- multiplexer. Each data channels are recovered by a PIN photo- detector and trans-impedance amplifier, retimed. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA) and compliant to IEEE 802.3ba. It has to be noted that the operation in excess of any individual absolute maximum ratings might cause permanent damage to this module. Minimum Order: 1 bags Contact:
