Chemical Explosion

The course and phenomena of oxygen cylinder explosion are introduced. Chemical composition analysis, mechanical properties, metallographic tests and spectrum analysis of the cylinder fragments have been carried out. Based on the fact that the explosion is concluded as a chemical explosion because of grease. Filling grease into oxygen cylinder was due to misuse. Violent oxidation exothermic reaction occurred when grease was exposed to pure high-pressure oxygen. The instantaneous releasing of heat produced extreme high temperature and extreme high pressure in the cylinder, which exceeded its limits and caused burst. During the process for risk, pressure gauge shows that cylinder explosion occurred while oxygen cylinder is charged to 13.5MPa. According to the GB 5099, the minimum explosion pressure of oxygen cylinder is 43.8MPa. Moreover, inverse calculation shows that minimum grease amount leading to burst of cylinder is between 79.6g to 95.5g. The experiences and lessons for the management and use of gas cylinder are discussed and emphasized.

Basic Characteristics

We designed and manufactured a prototype of a unique CMP machine, which can perform double-side CMP simultaneously in a sealed and pressure container as regarding effective action of the processing atmosphere around workpieces as important. Polishing experiments with single crystal silicon (Si) wafers (100) are performed by charging the container with various gases. As a result, the removal rates increased by up to 25% under high pressure oxygen gas atmosphere.
