Tantalum Boride powder is mainly prepared by thermal reduction of Tantalum penoxide powder and carbon black or graphite powder. The reaction equation is 2Ta205+B4C+15C+2B203 = 4TaB2+16C0. The above reaction processes belong to the solid-solid reaction type, and the reaction process is controlled by material diffusion. The disadvantages of this method are that the mixing of Tantalum pentoxide powder with carbon black or graphite powder is uneven and the activity of carbon black or graphite powder is low, which makes Tantalum pentoxide powder reduce incomplete and become impurities of the product. In addition, the carbon black or graphite powder remaining in Tantalum Boride powder has low activity, and a high temperature (> 600°C) is required during decarburization to generate carbon monoxide or carbon dioxide in the oxidizing atmosphere to eliminate C. The higher the temperature is, the higher the oxygen content of the powder will be, resulting in the quality decline of Tantalum Boride powder.
The pipe has the characteristics of high melting point, corrosion resistance and good cold working performance. Pipes are widely used in chemical industry, high temperature technical field and atomic energy industry, mainly used in the manufacture of chemical process reaction vessels and heat exchangers, pipes, condensers, bayonet heaters, spiral coils, U-shaped pipes, thermocouples and their protective pipes, liquid metal containers and pipes. Bar materials are widely used in aviation and aerospace industry, high temperature technology, atomic energy industry and chemical industry, mainly used for the production of supersonic aircraft, rocket engine, spacecraft combustion chamber parts, high temperature resistant furnace parts, nitric acid, sulfuric acid, hydrochloric acid corrosion resistant parts.
