Lead

Lead is a main-group element. It is also counted as one of the heavy metals. It is used in building construction, lead-acid batteries, bullets and shots, weights, as part of solders, pewters, fusible alloys and as a radiation shield. It is also used as electrodes in the process of electrolysis. Lead compounds are used as a coloring element in ceramic glazes, notably in the colors red and yellow. It is frequently used in polyvinyl chloride plastic, which coats electrical cords. Lead, at certain exposure levels, is a poisonous substance to animals. It damages the nervous system and causes brain disorders. Excessive lead also causes blood disorders in mammals. It is restricted under the RoHS directive.

Lead Monoxide

Lead monoxide is an inorganic compound. It is produced on a large scale as an intermediate in the conversion of lead ores, mainly galena into metallic lead. The consumption of lead, and hence the processing of PbO, correlates with the number of automobiles because it remains the key component of automotive lead-acid batteries. It is used extensively in manufacturing of lead glasses and ceramic glazes as well as in fine dinnerware. Other less dominating applications include the vulcanization of rubber and the production of certain pigments and paints. It is used in cathode ray tube glass to block X-ray emission, but mainly in the neck and funnel because it can cause discoloration when used in the faceplate. Strontium oxide is preferred for the faceplate. PbO is used in certain condensation reactions in organic synthesis.

Lithium

Lithium is a metal that belongs to the alkali metal group of chemical elements. Under standard conditions it is the lightest metal and the least dense solid element. Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, high strength-to-weight alloys used in aircraft, lithium batteries and lithium-ion batteries. Lithium niobate is used extensively in telecommunication products such as mobile phones and optical modulators, for such components as resonant crystals. Lithium is also used in the pharmaceutical and fine-chemical industry in the manufacture of organolithium reagents, which are used both as strong bases and as reagents for the formation of carbon-carbon bonds. Organolithium compounds are also used in polymer synthesis as catalysts/initiators in anionic polymerization of unfunctionalized olefins. Lithium compounds continue to be the gold standard for the treatment of bipolar disorder and are helpful for related diagnoses, such as schizoaffective disorder and cyclic major depression.
