Pyridine The Hantzsch pyridine synthesis typically uses a 2:1:1 mixture of a β- keto acid (often acetoacetate), an aldehyde (often formaldehyde), and ammonia or its salt as the nitrogen donor. First, a double hydrogenated pyridine is obtained, which is then oxidized to the corresponding pyridine derivative.yridine is a basic heterocyclic organic compound with the chemical formula C5 H5 N. It is structurally related to benzene, with one methine group (=CH-) replaced by a nitrogen atom.

Nitride Because boron and nitrogen together contain the same number of valence electrons (eight) as two bonded carbon atoms, boron nitride is said to be isoelectronic with elemental carbon. Boron nitride exists in two structural forms, which are analogous to two forms of carbon—graphite and diamond.

What are The Uses of Tantalum Tantalum features a high degree of biocompatibility. For this reason, it is used in medical technology as a radiographic contrast agent and in the production of bone replacement material and implants. In the aerospace and energy industries, tantalum increases the corrosion resistance of alloys in turbine blades. Tantalum's chemical corrosion and high temperature resistance properties provide many benefits to the chemical process industry. For this reason, tantalum is used in the production of reactor coatings, heat exchangers and pipelines. Its ability to form an extremely thin oxide coating which provides a protection layer, makes tantalum the material of choice in the production of small, high quality capacitors.

Tantalum Tantalum is a chemical element with symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum.

Titanium The two most useful properties of the metal are corrosion resistance and the highest strength-to-density ratio of any metallic element. In its unalloyed condition, titanium is as strong as some steels, but less dense.itanium is one of the few elements that burns in pure nitrogen gas, reacting at 800 °C (1,470 °F) to form titanium nitride, which causes embrittlement. Because of its high reactivity toward oxygen, nitrogen and some other gases, titanium filaments are applied in titanium sublimation pumps as scavengers for these gases.
