Granular powder

Psyllium Hydrophilic Mucciloid. Metamucil, or psyllium hydrophilic mucciloid, is a white-to-cream colored, slightly granular powder having Htde or no odor and a slightly acidic taste. It is made from the mucilagiaous portion, ie, outer epidermis, of blond psylHum seeds (Plantago ovatd).

Note Powder is a generic term for subdivided solid material, comprising pellets, granules and dust. Pellets have a diameter greater than 2 mm (U.S. No. 10 Standard Sieve) and typically above 3 mm. Granules have a diameter between 0.42 and 2 mm, although granular powders typically contain dust. Dusts have a diameter less than 0.42 mm and as low as I pm. Suspensions of particles smaller than I pm are known as fumes. 

The activated carbon materials are produced by either thermal or chemical activation as granular, powdered, or shaped products. In addition to the form of the activated carbon, the final product can differ in both particle size and pore structure. The properties of the activated carbon will determine the type of application for which the carbon will be used.

The brown oxide is a heavy granular powder which settles to the bottom of the solution in the bottle in which the reduction is carried out (p. 10). It must be reduced to platinum black before it becomes a catalyst for the reduction. When the hydrogen is admitted and the bottle shaken the brown oxide becomes black and whips up into a fine suspension. The time necessary for the change of the oxide to platinum black is called the lag. The time of lag varies usually from several seconds to two or three minutes, depending upon the conditions under which...

The feasibility of carbon-supported nickel-based catalysts as the alternative to the platinum catalyst is studied in this chapter. Carbon-supported nickel (Ni/C, 10 wt-metal% [12]), ruthenium (Ru/C, 10 wt-metal% [12]), and nickel-ruthenium composite (Ni-Ru/C, 10 wt-metal%, mixed molar ratio of Ni/Ru 0.25,1,4, 8, and 16 [12]) catalysts were prepared similarly by the impregnation method. Granular powders of the activated carbon without the base pretreatment were stirred with the NiCl2, RuC13, and NiCl2-RuCl3 aqueous solutions at room temperature for 24 h, respectively. Reduction and washing were carried out in the same way as done for the Pt/C catalyst. Finally, these nickel-based catalysts were evacuated at 70°C for 10 h. 

When the test substance is in flake, granular, powder, or other particulate form, the amount that has a volume of 0.01 ml (after gently compacting the particles by tapping the measuring container in a way that will not alter their individual form) is used whenever this volume weighs less than 10 mg.

Dichloro-dihydroxylamino-palladium, [Pd(NH2QH)2Cl2], is one of the products isolated when hydroxylamine hydrochloride, sodium carbonate, and palladous chloride interact. It appears to exist in two forms, and separates in long, slender, yellow needles or as a yellow granular powder. Owing to its instability the investigation of the series to which it belongs is difficult.1...
