	British Pharmaceutical Codex 1911: KIESELGUHR. (Site not responding. Last check: 2007-10-20)
		Kieselguhr is a siliceous deposit, formed chiefly of the frustules and fragmentary debris of diatoms—minute unicellular plants—which have accumulated in the depths of lacustrine districts.
		Kieselguhr occurs as a whitish, or slightly buff-coloured, fine, gritty powder, which is odourless, tasteless, and unaffected by all ordinary solvents.
		Kieselguhr is also used as a filtering medium, to clarify syrups and other liquids; for this purpose the powder should be triturated in a mortar with a little of the liquid before being added to the bulk of liquid to be filtered.

		This kieselguhr dynamite is generally made by incorporating three parts of nitroglycerin with one part of the dry earth, the paste being then formed into cylindrical cartridges.
		Generally a small percentage of the kieselguhr is replaced by a mixture containing sodium and ammonium carbonates, talc and ochre.
		Disabilities attaching to kieselguhr dynamite are that when place~d in water the nitroglycerin is liable to be exuded or displaced, also that, like nitroglycerin itself, it freezes fairly easily and thawing the frozen cartridges is a dangerous operation.

	Kieselguhr
		Kieselguhr, a diatomaceous earth (diatomite) is a form of silica composed of the siliceous shells of unicellular aquatic plants of microscopic size.
		Kieselguhr is heat resistant and has been used as an insulator, as a component in toothpaste and as an abrasive in metal polishes.
		In the chemical industry, it is also used as a filter to clarify syrups and sugar and as a filling material in paper, paints, ceramics, soap and detergents.

	Palladium/kieselguhr composition and method - Patent 5248649
		The hydrogen-absorbing composition in its preferred embodiment comprises palladium, a metal hydride, uniformly distributed throughout the interior of a kieselguhr substrate, preferably in the form of granular (30-40 mesh) kieselguhr particles.
		In addition to using kieselguhr particles as the preferable substrate for palladium, other support materials such as substrates made of glass frit, quartz frit, and sintered aluminum may be used.
		If the palladium deposited within the kieselguhr substrate does not comprise the desired percent by weight of the composition, the process steps are repeated until the desired amount of palladium is deposited within the kieselguhr.

		The role of the filter sheet is to capture the kieselguhr filter medium and help establish the build up of the filter cake within the filter.
		In most breweries it is impractical to add kieselguhr powder in bulk to the beer prior to filtration.
		Consequently this is usually achieved with automatic dosing equipment, which injects metered quantities of kieselguhr in slurry form into the beer flow line.

	PLK Chromatography
		The DNA molecules in the broken cell mixture bind exclusively to the poly-lysine, which is in turn bound to the white kieselguhr powder, making an insoluble compound substance.
		This removes all the other cell-contents and leaves the DNA bound to the poly-lysine, which is in turn bound to the solid kieselguhr.
		The DNA molecules are released from their complex with the poly-lysine kieselguhr (PLK) by passing stronger and stronger solutions of salt through the column of PLK and DNA.

		Perlite and kieselguhr are used as filter media and filter aids for filtration of suspensions of different nature.
		Simultaneously, kieselguhr filter aids, represented by highly irregular particles, may represent an excellent experimental model for the investigation of the behaviour of mixtures of irregular particles with regular (granular) material.
		The curve ABCD may be due to the fact that kieselgel and kieselguhr-G fill the void between large particles; in turn the curve ABD may be explained by intrusion of fine particles in the skeleton of the large particles.

		1,000 grams of brewers' yeast,[1] purified for the preparation of pressed yeast but still not treated with potato starch, is carefully mixed and then rubbed with an equal weight of quartz sand[2] and 250 grams of kieselguhr, until the mass becomes moist and plastic.
		The paste is then treated with 100 grams of water and, wrapped in a press cloth, is placed gradually under a pressure of 4 to 500 atmospheres: 300 cubic centimeters of press juice result.
		To remove traces of cloudiness, the press juice is finally shaken with 4 grams of kieselguhr and filtered through a paper filter with repeated refiltrations for the first portions.

		The process is based upon Cross flow microfil-tration, which in the past has been tried and tested many times, but has never been able to become a technically and economically feasi-ble alternative to conventional kieselguhr filtration.
		This was mainly due to high fouling rates of the membranes, short run times and inad-equate cleaning procedures.
		Preliminary results show that this technology will be able to replace kieselguhr filtration in breweries from a technical as well as an economical point of view.

		He coined the name from the Greek dynamis, “power.” The basis for the invention was his discovery that kieselguhr, a porous siliceous earth, would absorb large quantities of nitroglycerin, giving a product that was much safer to handle and easier to use than nitroglycerin alone.
