Which property does boron phosphide have?
Due to different preparation methods,
red, red transparent or dark red transparent crystals. It is stable chemically and does not disintegrate in hydrochloric or sulfuric acids, hydrofluoric and other mixed acids.
Boronphosphide shares many properties with refractory substances. Boron phosphide is hardier than silicon carbide, but it also has a higher energy gap. The anti-oxidation properties of boron phosphide can be seen even at temperatures up to 800 degrees Fahrenheit. If boronphosphide heated at high temperatures it loses the phosphorous and leaves a dark gray residue. Bromine and chlorine are the coldest places for boron phosphide to ignite. It is brightly visible in oxygen at 200°C, and it can be broken down by all metals using red heat.
What’s the purpose of boronphosphide in everyday life?
A boron-phosphide film can transmit light in wide wavelengths and is resistant to rain erosion. It also has the fastest damage threshold speed (DTV). Boron phosphide films have better mechanical properties than germanium carbide. A thin layer of boronphosphide can adhere well to many base materials. It is also easier to apply an internal stress to other bases. Boron phosphide could be used as an anti-reflection protection film in high-speed flying infrared window windows.
Scholars are now increasingly interested in the protection of boronphosphide films on parts in harsh environments. Boronphosphide is a good choice for corrosion-resistant films of infrared windows on submarine telescopes. When the submarine’s telescope window is out at sea, it must be immersed into the ocean water. To maintain the wavelength and resolution of the camera’s photoelectric system, the window should be high-transmitting. It also must resist corrosion in seawater. To preserve the original optical performance, the boron-phosphide window can be protected against seawater erosion by using a boron phosphide folio.
