Zinc compounds are generally colorless unless the other component, eg, chromate, is colored. The lack of color of most zinc compounds in visible light is a great advantage in that they do not color paint films, plastics, mbber, cosmetics, etc. However, when excited by various types of radiation and at various temperatures, zinc oxide, sulfide, selenide [1315-09-9], and related compounds exhibit luminescence, ie, they emit colored light (see Luminescent materials). Zinc-based phosphors can be produced in many colors, depending upon the added dopants. They are used in television tubes, luminescent glasses, and various specialty products. 

Strontium carbonate occurs in nature as mineral strontianite. The compound is used in pyrotechnics and ceramic ferrites. It also is used in making iridescent glass for color television tubes. Other uses are in refining sugar and preparing other strontium salts. 

Unalloyed tungsten has several major applications. An important use is in the electric lamp filaments for light bulbs. Also, it is used as electrodes in arcwelding, in heating elements for high-temperature furnaces, in electron and television tubes, in glass-to- metal seals, and in solar energy devices. 

Compounds of lithium have a number of important uses. Two of the most significant applications are in the glass and ceramics field and in the production of aluminum. The addition of a small amount of lithium carbonate (Li2C03) to a glass or ceramic makes the material stronger. Examples of the use of lithium carbonate are shock-resistant cookware and black-and-white television tubes. 

Samarium looks and behaves like most other metals, but it has relatively few uses. One of the most important is in the manufacture of very powerful magnets. Compounds of samarium are also used to color glass and in television tubes.

Use Treatment of brines in chlorine-alkali cells to remove sulfates, rodenticide, production of barium salts, ceramic flux, optical glass, case-hardening baths, ferrites, in radiation-resistant glass for color television tubes. 

Use Catalyst, in radiation-resistant glass for color television tubes, ceramic ferrites, pyrotechnics. 

Now it is time to demonstrate air-free and matter-free spaces - the vacuum. If one demonstrates the mass of an air portion by weighing back an initially evacuated glass flask, then a central experiment has been carried out (see E3.13), i.e. one has experienced the practical evacuation of a flask. If one then conducts a discussion about the vacuum-packed food or evacuated television tubes , it becomes evident that matter-free space can be created by pumping out the air. One could also reflect upon the possibility of a real vacuum by calculating the steam pressure of water through the use of water jet pumps or the partial pressure of oil in oil pumps a remnant of steam of water or oil is always left after pumping out the air.

In the last chapter, we presented a synopsis of the technological advances made in CRT s, particularly those for the color TV tube up to about the mld-1960 s. Since that time, a number of innovations have been accomplished. This change has been in response to market demand for a less bulky display device as well as a larger display size, i.e.- the "flat" television tube. Major improvements have been created in the electron gun, deflection yoke and the glass faceplate. What we are addressing is the changes in t rpe of display which has resulted. In the ordinary CRT of the...
