Carlit - Carlit (English spelling)

Japanese: カーリット - かーりっと(英語表記)Carlit
Carlit - Carlit (English spelling)

Invented by the Swedish Oscar Birger Carlson (1873-1928), this explosive is based on perchlorate and contains more than 10% perchlorate. It was particularly developed in Japan, and was exclusively manufactured by Japan Carlit Co., Ltd. Its ingredients are ammonium perchlorate, ferrous silicon, wood powder, and heavy oil. Although it is powerful, it has problems with the after-gas, so it was used in open-cut limestone mining, but the after-gas was improved and it was also used underground. Ammonium nitrate oil explosives and water-containing explosives have replaced Carlit, and it has not been manufactured since 1998.

スウェーデンのカールソンOscar Birger Carlson(1873―1928)の発明した、過塩素酸塩を基剤とし、その含有量が10%を超える爆薬。とくに日本で発達し、日本カーリット株式会社で独占的に製造された。成分は過塩素酸アンモニウム、ケイ素鉄、木粉、重油などである。威力は強いものの、あとガス(後ガス)に問題があるので、石灰石の露天掘りなどに使われたが、後ガスを改良して坑内用にも使われた。硝安油剤爆薬や含水爆薬がカーリットにかわって用いられており、1998年(平成10)以降は製造されていない。
