...Nitroglycerin alone was too dangerous, so Nobel invented diatomaceous earth dynamite and gelatin dynamite to make it safer, and established nitroglycerin's position as an explosive material. In 1886, he also invented ballistite, a double-base smokeless powder made by mixing nitroglycerin with a large amount of nitrocellulose to make it gelatinous and insensitive to shock. Nitroglycerin is a colorless, transparent liquid with a sweet taste and a specific gravity of 1.60. From [Smokeless Powder]…B powder is the beginning of today's single-base smokeless powder. In 1888, A. Nobel of Sweden mixed nitrocellulose with about 12% nitrogen and nitroglycerin, kneaded and molded it to create a smokeless powder, which he called Ballistite. In 1889, F. Abel of England kneaded a mixture of nitrocellulose with more than 13% nitrogen and nitroglycerin with acetone, molded it, and evaporated the solvent to create a smokeless powder, which he named Cordite. … *Some of the terminology that mentions "ballistite" is listed below.

…またニトログリセリン単独では危険すぎるので,ノーベルはそれを安全にして使えるケイ藻土ダイナマイト,ゼラチンダイナマイトを発明して,ニトログリセリンの爆薬原料としての地位を確立した。さらに1886年にはニトログリセリンを多量のニトロセルロースと混ぜてゼラチン状とし,衝撃に対して鈍感にしたダブルベース無煙火薬(バリスタイトballistite)を発明している。 ニトログリセリンは無色透明の液体で,甘味を有し,比重1.60。… 【無煙火薬】より…B火薬は今日のシングルベース無煙火薬のはしりである。88年スウェーデンのA.ノーベルは窒素量約12%のニトロセルロースとニトログリセリンを混ぜて練って成形し無煙火薬をつくりバリスタイトBallistiteと呼んだ。89年イギリスのアーベルF.Abelは窒素量13%以上のニトロセルロースとニトログリセリンの混合物をアセトンで練って成形し,溶剤を飛ばして無煙火薬をつくり,これをコルダイトCorditeと命名した。… ※「ballistite」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
