		Caesium fluoride may be prepared by the action of hydrofluoric acid on caesium hydroxide or caesium carbonate, followed by removal of water.
		Caesium fluoride is a useful base in organic chemistry, due the fact that fluoride ion is largely unreactive as a nucleophile.

	Electron lithography mask manufacture - Patent 4608332
		The plate 6 coated with caesium iodide layer 9 is then transported along the barrel 2 to the area of the electron beam column chamber 4 which contains an electron beam column in the form of a so-called electron beam pattern generator which in its own right is well-known to those skilled in the art.
		Thus, in both cases a photocathode mask is formed by selectively exposing the layer 9 of caesium iodide on the transparent plate 6 to a focussed beam of electrons.
		The caesium iodide 9 can then be cleaned from the quartz plate 6 simply by rinsing in water and the quartz plate can be reused for another photocathode mask which may have the same or a different photoemissive pattern defined thereon in the same manner as already described.

		Caesium is a soft metal which is often liquid at room temperature due to its relatively low melting point (28.5°C).
		As with other alkaline group metals, caesium can be prepared by electrolysis of the fused halides but, in addition, it can also be prepared by heating the chloride with calcium and distilling out the molten metal.
		Caesium is also used in atomic clocks, a standard measure of time, based on the caesium ion resonance of 9,192,631,770 Hz.

		Sr, their half-lives of about 30 years, and the fact that caesium is chemically similar to potassium, and strontium is chemically similar to calcium, all combine to select these two radionuclides as potentially very significant to humans.
		Caesium is an alkali metal of Group I with properties similar to those of potassium and rubidium.
		Despite the chemical similarities between caesium and potassium, they are not metabolized identically, and although potassium is often used to model caesium environmental transport, there can be more similarities between calcium and caesium.

		Dysprosium and thallium iodides are the principal metal halide constituents, this chemistry causing the arc to become very constricted which leads to instability and a chance of flicker.
		Caesium iodide is therefore added to counter this effect and fatten the arc back to normal levels.
		The luminous efficacy is somewhat less than for lower colour temperature lamps, consequently the short arc in this lamp develops considerably more heat.
