Synthesis of silver bromide ultra fine-crystalline suspensions

Synthesis of silver bromide ultra fine-crystalline suspensions Agnieszka DYONIZY, Piotr NOWAK, Agnieszka KRÓL-GRACZ, Ewa MICHALAK ? Institute of Physical and Theoretical Chemistry, Wrocław University of Technology, Wrocław Please cited as: CHEMIK 2010, 64, 1, 33-44 This work present the results of research in ultra-fine crystals suspension of silver bromide crystals, which were received as high concentration sols stabilized by excess of bromide ions and gelatin. Relation between dosing rate of reactants to dispersion system and size of obtained silver bromide crystals was investigated. Alterations of...

Shaped charge and numerical modeling of their detonation

Shaped charge and numerical modeling of their detonation Andrzej WOJEWÓDKA, Janusz BEŁZOWSKI, Tomasz WITKOWSKI ? Faculty of Chemistry, Silesian University of Technology, Gliwice Please cited as: CHEMIK 2010, 64, 1, 25-32 The shaped charges are applied wide both in army, industry, how and the mining. They allow to become spoiled the elements of the enemy armament, and also make possible the perforation of drilling openings in the trade of gas and petroleum. Numerical modeling the process of the detonation of shaped charges, projecting allows to...

Coordination explosives

Coordination explosives Janusz BEŁZOWSKI, Andrzej WOJEWÓDKA ? Faculty of Chemistry, Silesian University of Technology, Gliwice, Marcin ROMANOWSKI ? Institute of Heavy Organic Synthesis ?Blachownia?, Kędzierzyn-Koźle Please cited as: CHEMIK 2010, 64, 1, 21-24 The history and evolution of explosives reach about two millennia backwards. Starting form the black powder, thought nitro-compounds and nitro-esthers, current directions of researches concern coordination transition metal compounds, called compounded salt. This researches leads to a number of new chemical structures which posses explosive parameters, just like blasting or primary explosives and propellants. Keywords:...

Modern high-energetic polymers

Modern high-energetic polymers Karol KOŻUCH, Andrzej WOJEWÓDKA ? Faculty of Chemistry, Silesian University of Technology, Gliwice Please cited as: CHEMIK 2010, 64, 1, 15-20 The article is about new high-energetic polymers. This article comprises two main sections. The first section outlines historical background of using high energetic polymers, gives basics theory of explosives and chemistry of high energetic materials. The second part contain description of high energetic polymers which seems to be the most prospective. Attention, in this part of article, is focused on several...

Polyolefin composites for special applications

Polyolefin composites for special applications Marcin ROMANOWSKI ? Institute of Heavy Organic Synthesis ?Blachownia? Kędzierzyn-Koźle, Janusz BEŁZOWSKI ? Faculty of Chemistry, Silesian University of Technology, Gliwice, Bartłomiej KRAMARCZYK - Nitroerg S.A., Bieruń, Aneta BULSKA - Nitroerg S.A., Bieruń Please cited as: CHEMIK 2010, 64, 1, 7-13 The article presents wide spectra of applications of polyolefin composites as materials for special purposes. These polymers are used as binders in plastic bonded explosives, in rocket propellants, in safe optical priming charges as well as in...
