Chagang
Chagang Province (Chagangdo; ) is a province in North Korea; it is bordered by China's Jilin and Liaoning provinces to the north, Ryanggang and South Hamgyong to the east, South Pyongan to the south, and North Pyongan to the west. Chagang was formed in 1949, after being demarcated from North Pyongan. The provincial capital is Kanggye. Before 2019, Chagang was the only province of North Korea completely inaccessible to tourists, possibly due to weapons factories and nuclear weapon facilities located there. In 2019 the city of Manpo became accessible to tourists. In May 2018, the province became a "Special Songun (military first) Revolutionary Zone" in relations to concealing the nuclear weapon and weapon's factories within the province. Geography Chagang Province is located in the northwestern part of Korea. It is a mountainous province; with the mountainous area amounting to 98 per cent of its total area. The mean height above sea level is 750 meters and the slope of mos ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lead
Lead is a chemical element with the Symbol (chemistry), symbol Pb (from the Latin ) and atomic number 82. It is a heavy metals, heavy metal that is density, denser than most common materials. Lead is Mohs scale of mineral hardness#Intermediate hardness, soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable nuclide, stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and base (chemistry), bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighte ...

Fluorite
Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as fluorite. Pure fluorite is colourless and transparent, both in visible and ultraviolet light, but impurities usually make it a colorful mineral and the stone has ornamental and lapidary uses. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels. The purest grades of fluorite are a source of fluoride for hydrofluoric acid manufacture, which is the intermediate source of most fluorine-containing fine chemicals. Optically clear transparent fluorite lenses have low dispersion, so lenses made from it exhibit less chromatic aberration, making them valuable in microscopes and telescopes. Fluorite optics ar ...

Kanggye Line
The Kanggye Line is an electrified narrow-gauge line of the Korean State Railway in North Korea running from Kanggye on the Manp'o Line to Rangrim,Kokubu, Hayato, 将軍様の鉄道 (Shōgun-sama no Tetsudō), primarily hauling forest products. An interesting feature of the line is a significant switchback west of Rangrim. History The Kanggye Line was built by the Korean State Railway in the late 1940s to aid in the construction of a hydroelectric dam on the Changjin River in the Rangrim mountains; construction of the dam had been started by the Japanese in 1937. Following an order issued in September 1999 by Kim Jong-il, electrification of the line at 1500 V DC was completed on 5 October 2000. Route A yellow background in the "Distance" box indicates that section of the line is not electrified; a pink background indicates that section is narrow gauge A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard .

Graphite
Graphite () is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes. Under high pressures and temperatures it converts to diamond. It is a weak conductor of heat and electricity. Types and varieties Natural graphite The principal types of natural graphite, each occurring in different types of ore deposits, are * Crystalline small flakes of graphite (or flake graphite) occurs as isolated, flat, plate-like particles with hexagonal edges if unbroken. When broken the edges can be irregular or angular; * Amorphous graphite: very fine flake graphite is sometimes called amorphous; * Lump graphite (or vein graphite) occurs in fissure veins or fractures and appears as massive platy intergrowths of fibrous or acicular cry ...
