South Hamgyong Province
South Hamgyong Province (, ''Hamgyŏngnamdo''; ) is a province of North Korea. The province was formed in 1896 from the southern half of the former Hamgyong Province, remained a province of Korea until 1945, then became a province of North Korea. Its capital is Hamhung. Geography The province is bordered by Ryanggang to the north, North Hamgyong to the northeast, Kangwon to the south, and South Pyongan to the west. On the east of the province is the Sea of Japan. Administrative divisions South Hamgyong is divided into three cities ("si"), two districts (one "gu" and one "chigu"), and 15 counties ("gun"). These are further divided into villages ('' ri'' and '' dong'', with dong also denoting neighborhoods in cities), with each county additionally having one town ('' up'') which acts as its administrative center.

Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...
