Burning Rate and Grain Size of Component Materials of Pyrotechnic Mixtures
Dr Takeo Shimizu ABSTRACT: It has been generally believed that the finer the grain size, the faster the burning when we select the component materials of a pyrotechnic mixture. It is not always true because a small explosion occurred in the past when we tested a smoke mixture, although it contained a dye of very …

Stabilizing Firework Compositions – I. Minimum Solubility Law to Foresee the Degeneration, II. A New Chemical Method of Magnesium Coating
Dr Takeo Shimizu ABSTRACT: These studies concern two important problems at present: one is how to select the component materials of a mixture not to cause degeneration, and another is to find a more effective method of magnesium coating than those at present. A firework mixture generally consists of several solid materials which are closely …

The Surface Explosion of Pyrotechnic Mixtures
Dr Takeo Shimizu ABSTRACT: In the past we sometimes observed a fairly large burning star caused an explosion with a loud noise at the very moment when it fell onto the ground. The star did not explode totally, but only with the thin surface layer. The burning surface layer of the star may be very …

The Effect of Hot Spots on Burning Surface and Its Application to Strobe Light Formation with Mixtures Which Contain No Ammonium Perchlorate
Dr Takeo Shimizu ABSTRACT: The objective of this work was to make clear the effect of hot spots or hot spot materials on burning pyrotechnic compositions and to find practicable strobe light compositions without ammonium perchlorate which is not always popular in the firework field, using the effect of hot spot materials. As the hot …

An Example of Negative Explosives: Magnesium Sulfate/Magnesium Mixture
Dr Takeo Shimizu ABSTRACT: At the Eleventh International Pyrotechnics Seminar, 1986, in Vail, Colorado, I reported on a study of pyrotechnic mixtures with a theme, “A Concept and the Use of Negative Explosives”. A further study has been continued on the same subject as before. In the former report it was known that magnesium sulfate/magnesium …

Ballistics of Firework Shells
Dr Takeo Shimizu ABSTRACT: Heretofore we have had four important problems with calculations in this field, i.e., with the interior ballistics when using Black Powder as the propellant: (1) to obtain a suitable form function of the propellant which consists of irregular grains, (2) to obtain solutions when the burning rate ofthe propellant grains is …
