EVALUATION OF THE MICROTRAC (SPA) FOR PARTICLE SIZE ANALYSIS OF SUPERFINE ^jfihT MATERIALS
نویسنده
چکیده
INTRODUCTION The solid propellant industry has until recently used the MSA particle size analyzer for the analysis of superfine materials. Since MSA equipment is no longer manufactured and MSA test time is fairly lengthy in the superfine region, other methods were investigated by Atlantic Research Corporation. After investigating several instruments, it was decided that the Microtrac small particle analyzer (SPA), manufactured by the Leeds and Northrup Company, Microtrac Division, would meet the requirements of accuracy, precision, simple operation and rapid analysis time in the superfine region. v .v .«. -

Preparation of micron and nano sized ammonium perchlorate (AP) particles in propellant formulation is required for access high burning rate propellants. The decomposition and burning rate of AP particles are mainly affected by decreasing the particle size, which can decrease the decomposition temperature, and increase burning rate. AP particles at the micro and nano-scales, have a great influe...

Background and purpose: Staphylococcus aureus is the most common causes of hospital and community acquired infections. Nasal carriage of S. aureus in staff provides a source for infection in hospitalized patients. The aim of this study was to evaluate the spa gene patterns of clinical and nasal carriage isolates of S. aureus using polymerase chain reaction. Materials and methods: Clinical spec...
متن کاملEffects of the pH of Initial Solution on Hydrothermally Synthesized TiO2 Nanoparticles
In this paper, we focused on the effects of initial solution’s pH on the composition, structure and morphology of hydrothermally synthesized titanium oxide nanoparticles. TiCl4 and NaOH were used as titanium source and precipitant, respectively. Phase and structure determination of samples were obtained by X-ray diffraction (XRD) analysis. Scanning electron microscopy (SEM) images were used for...
