Zeolite - Wikipedia

2019-5-7 · Zeolites are microporous, aluminosilie minerals commonly used as commercial adsorbents and alysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.

Barium chlorate | Ba(ClO3)2 - PubChem

A solution of barium chloride was injected intramuscularly into five children and intravenously into two adults, all with normal skeletal metabolism. Three of the children and one adult also received calcium chloride in the same injection. Following injection, the concentration of barium in the serum fell rapidly for about 0.6 day and then more slowly; even so, the amount detected on day 6 was
