So here's what the article says. The last part is very scary.
" Yu-8 (鱼-8) torpedo is developed by China as the electrically powered counterpart of the Chinese Otto fuel II powered Yu-6 torpedo, with which it shares many components and technologies, with the exception of propulsion system.
Since Otto fuel II powered torpedo cost up to three times of the electrically powered torpedo, Yu-8 torpedo is developed as a cheaper alternative. Very little information is released regarding the torpedo and this new torpedo is shrouded in secrecy. From the very limited information circulating, it is revealed that Yu-8 (鱼-8) torpedo is capable of both ASuW and ASW like Yu-6 torpedo, and it can be launched from a variety of platforms including surface ships, submarines, shore battery, and aircraft. Like all other Chinese torpedoes, Yu-8 torpedo can also be used as part of CAPTOR mine type mine system. Yu-8 torpedo is reportedly the first Chinese torpedo to incorporate wire guidance with optical fiber.
In 2007, domestic Chinese sources have claimed that Yu-8 torpedo had become the test vehicle and subsequently the first torpedo to be armed with a new warhead that was developed by the Chinese naval research institute. The new warhead utilizes sodium hydride compounds / chemical reaction and once detonated, large amount of sodium powder is released. The chemical reaction of sodium powder and sea water produce huge amount of hydrogen at very high temperature within very short period of time and the within range of several dozen meters, the temperature instantly increased to over two thousand degrees (celsius) as the chemical reactions taken place with hydrogen and oxygen, destroying the target even if no direct hit is scored. During the test in East China Sea, a retired twelve thousand ton ship was hit by two Yu-8 torpedoes on one side, and the side that was hit was completely melted within fifteen minutes. "
