Boride for rocket construction
What products are boride used in?
Boride
has the characteristics of high conductivity, high melting point, high hardness and high stability: Boride has high thermal conductivity and strength, so its thermal stability is good, the oxidation resistance of Boride at high temperature is better than that of Group IV B Metal Boride. Boride is soluble in Molten Alkali, and Boride of rare earth and alkaline Earth metals is not corroded by wet air or dilute hydrochloric acid, but is soluble in nitric acid.
Almost all boride compounds have metallic appearance and properties, with high conductivity and positive resistance-temperature coefficient. The boride of Ti, Zr, HF has better conductivity than its metal. The creep resistance of Boride is very good, which is very important for gas turbine, rocket and so on, which requires the material to work long-term under high temperature and can keep strength, resist deformation, resist corrosion, resist heat shock. Any of various alloys or cermets based on boride, carbide, or nitride, it can be used in the manufacture of rocket structural components, aeronautical device components, turbine components, specimen clamps and instrument components of high-temperature material testing machines, bearings and cone heads for measuring high-temperature hardness, and certain structural components of nuclear energy devices, etc.
Are Boride ceramics fragile?
Boride ceramics have high conductivity, high melting point, high hardness and high thermal stability. Boride is usually produced by normal pressure sintering, hot pressing sintering or ISOSTATIC pressing sintering after conventional molding or injection molding.
What are boride compounds?
A binary compound of Boron with metals and certain nonmetals, such as carbon. MMBN can be expressed as a general formula. It is usually an interfilling compound and does not follow the valence rule. In addition to zinc (Zn) , cadmium (CD) , Mercury (Hg) , gallium (Ga) , indium (In) , thallium (Tl) , Germanium (GE) , tin (Sn) , lead (PB) , Bismuth (Bi) , other metals can form boride. They are crystals of high hardness and melting point, stable in chemical property, insoluble in hot concentrated nitric acid, and can be obtained by direct combination of elements or by reduction of oxides with active metals, used for fire resistance, grinding, and Superconductor classification.
The role of Boride in superalloys micronutrient ?
B is widely added to almost all commercial superalloys to improve high temperature serviceability. It is generally believed that B tends to segregate at grain boundaries, which helps to inhibit the migration of grain boundaries at high temperatures. B exists in two forms in superalloys, one in the form of solid solution and the other in the form of boride precipitates. The solid solubility of B in superalloy is very low, so a variety of boride, such as M2b, M3B2 and M5B3, will be precipitated during high temperature service. Although these boride compounds are ubiquitous in superalloys, people still know about them on the relative macro-scale such as morphology. The further understanding of the fine structure of precipitates is helpful to optimize the material design and elaborate the structure-performance relationship reasonably.
