Abstract
게르마니움(Ge)은 일반에게 잘 알려져 있지 않은 희귀식품으로써 원자번호는 32, 원자량 72.6, 융점 936±1℃, 비중 5.325의 구조와 성질을 갖는 금속으로서 알려져 있다. 이러한 게르마니움 금속은 용도에 따라서 일정한 모양으로 성형하고 사용상 지장이 없을 정도의 강도를 유지하기 위한 수단으로서 열처리를 해야 하는데 게르마니움 자체로서 열처리 할 적에 700℃ 이상에서는 산화되어 그 자체의 성질을 잃어버리는 경향이 있고, 700℃이하에서는 강도가 발현되지 않는 문제점이 있었고, 쎄라믹 계통에서 사용하는 결합제인 점토나 기타 점결제로서 사용할 경우 열처리 온도에 맞지 않거나 게르마니움의 성질과 맞지 않다는 결점 때문에 게르마니움의 제조에 어려움이 있었다. 상기 본 발명은 게르마니움의 100중량부의 결합제로서 탄산은, 불화은, 산화은, 인산은, 유화은, 황산은, 요소은, 시안화은, 질화은, 염화은을 금속으로서는 알루미니움, 아연을 1종 또는 2종 이상을 5-70중량부를 혼합하여 성형하고 산화 분위기중 700℃이하에서 또는 진공부위중 930℃이하에서 열처리한 것을 특징으로 하는 게르마니움의 제조방법이다.Germanium (Ge) is a rare food that is not well known to the general public. It is known as a metal having the structure and properties of atomic number 32, atomic weight 72.6, melting point 936 ± 1 ° C, specific gravity 5.325. These germanium metals are shaped to a certain shape according to the purpose of use and must be heat treated as a means to maintain the strength to the extent that they do not interfere with use. Germanium itself is oxidized at 700 ° C or higher when it is heat treated, There is a problem in that the strength is not exhibited at 700 DEG C or less, and when it is used as a binder for clay or other binder used in the ceramic system, it is not suitable for the heat treatment temperature or is incompatible with the properties of germanium, There was difficulty in manufacturing manium. The present invention relates to a process for the production of germanium, which comprises mixing 100 parts by weight of at least one metal selected from the group consisting of silver carbonate, fluoride, silver oxide, phosphoric acid, emulsion silver, sulfuric acid, urea silver, silver cyanide, silver nitrate, Treated at a temperature of 700 ° C or lower in an oxidizing atmosphere or at 930 ° C or lower in a vacuum region.
