strontium in diatomaceous earth :

Strontium molybdate as a replacement for barium

In this work, replacement of barium chromate (BaCrO 4 ) in the traditional tungsten delay (W/BaCrO 4 /KClO 4 /Diatomaceous Earth (DE)) with strontium molybdate (SrMoO 4 ) is explored both mechanistically and as an environmentally friendly alternative to currently fielded time delays. Delay performance and aging characteristics are examined at similar diameters (4.7 mm) to common delay housings.

Effect of plaque of five toothpastes used in the treatment ...

1990-10-1  During the use of a diatomaceous earth/strontium chloride toothpaste, commercially available, plaque scores increased significantly, both from baseline and by comparison with the other four pastes. Nevertheless, plaque scores in this group returned to baseline levels after cessation of treatment and a return to use of a conventional non ...

2017-2-28  Modification of diatomaceous earth (DE) was performed using alkyltrimethoxysilanes of different chain lengths (C3, C8, C12, C16, and C18), and their resultant properties were determined. The thermal properties of these alkyltrimethoxysilane-treated DE powders were probed using thermogravimetric analysis and temperature-modulated differential scanning calorimetry, and the

Strontium Carbonate Toxicity Note - Digitalfire

Strontium Carbonate Toxicity Note. The greatest danger to humans is from artificial isotopes 89Sr and 90Sr produced in nuclear reactions; fallout of 90 Sr mainly from atmospheric nuclear explosions (and power-plant reactor accidents) has caused great concern. These isotopes are deposited in bones, acting as a source of internal radiation.

Results: In the XRD patterns, the film sputtered from a diatomaceous earth target under 5.0 Pa of Ar pressure showed aluminosilicate peaks (Na1.82(Al2Si3O10) and Al2SiO5) after 8 h of vapor-phase hydrothermal treatment. The film showed higher adsorption of Cs than Sr in Cs and Sr solutions, while the HA film adsorbed far more Sr than Cs.
