Gold color

Potassium Graphite. Potassium, mbidium, and cesium react with graphite and activated charcoal to form intercalation compounds CgM, C24M, C gM, C gM, and C qM (61,62). Potassium graphite [12081 -88-8] 8 P gold-colored flakes, is prepared by mixing molten potassium with graphite at 120—150°C. 

Gold [7440-57-5] Au, is the principal constituent of gold-colored alloys. It contributes gold color kicreases the specific gravity raises the melting pokit, if that of the alloy is below that of gold and kicreases ductihty, maHeabiUty, corrosion, and stain resistance. Gold produces heat-treatable compositions with copper, platinum, and zkic. It is useful ki amounts of 25—100 wt %. 

Platinum [7440-06-4], Pt, detracts from the gold color, produckig an undeskable grayish-red color kicreased platinum produces a platinum-colored ahoy. Platinum kicreases strength, proportional limit, and solidification temperatures reduces grain size and produces a heat-treatable ahoy with gold. It has a useful range of 0—18 wt %. 

GoldJilloys, Wrought Type. Two types of wrought gold alloys were formerly recognized by the ADA specification no. 7 for the fabrication of orthodontic and prosthetic dental appHances, ie, type I, high-precious-metal alloys, and type II, low-precious-metal alloys (gold color). Alloys of this type are seldom used in the United States they have been replaced by stainless steels and nickel—titanium alloys. 

FIGURE 14.17 A diaphragm cell tor the electrolytic production of sodium hydroxide from brine (aqueous sodium chloride solution), represented by the blue color. The diaphragm (gold color) prevents the chlorine produced at the titanium anodes from mixing with the hydrogen and the sodium hydroxide formed at the steel cathodes. The liquid (cell liquor) is drawn off and the water is partly evaporated. The unconverted sodium chloride crystallizes, leaving the sodium hydroxide dissolved in the cell liquor.

The earliest use of gold complexes in medicine primarily involved gold thiolates, which being yellow or even gold-colored in solution, led to their designation as chrysotherapy (chrysos is Greek for gold). 

T Name from zargun (Arabic = gold color), a reference to the semiprecious stone zircon. 

React in the dark for 15-20 minutes at room temperature. If HRP is the enzyme being oxidized, a color change will be apparent as the reaction proceeds—changing the brown-ish/gold color of concentrated HRP to green. Limiting the time of oxidation will help to preserve enzyme activity.

ORIGIN OF NAME The name "zirconium" was derived from the Arabic word zargun, which means "gold color." Known in biblical times, zirconium mineral had several names (e.g., jargoon, jacith, and hyacinth). Later, the mineral was called "zirconia," and the element was later named "zirconium."... 

The polycrystalline 2H(a)-TaS2 should be free flowing and in the form of black platelets. Any gold-colored material indicates the presence of the IT phase and results from improper annealing. Further, the presence of a fibrous or needlelike material indicates incomplete reaction of the tantalum. This fibrous material is most likely TaS3, which decomposes above 650°.14... 

Orpiment of gold color, 20 drachmas powdered glass, 4 staters or white of egg, 2 staters white gum, 20 staters saf ran. . After writing, let it dry and polish with a tooth. (An animal s tooth used by jewelers for polishing.)... 

In other recipes, the yellow or gold color is obtained by sulphur mixed with gum the bile of the tortoise, or of the calf, very bitter, serves also for the color. These may be secret trade names for some substances of different character. 

The chrysolith according to Pliny is a yellow or gold-colored stone. The above recipe merely covers the clear crystal with a yellow varnish. 

A deep yellow was to be obtained by using gold-colored... 

Chelidony 3 drachmas, fresh and clear resin 3 drachmas, gum of gold color 3 drachmas, brilliant orpiment 3 drachmas, bile of the tortoise 3 drachmas, white of egg 5 drachmas. The whole makes 20 drachmas. Add 7 drachmas of safran of Cilicia. You can write with it not only upon parchment or paper but also on a glass vessel or on marble.
