Overview of Boron Phosphide BP Powder
Boron phosphide is a dark blue or black solid powder with BP's chemical formula. It has a hexagonal crystal structure with high thermal conductivity and good chemical stability. Boron phosphide is insoluble in water and dilute acid but soluble in concentrated acid and alkali at room temperature. It has high hardness, brittleness, high melting point, and a small thermal expansion coefficient, making it a good thermal conductive material.
Boron phosphide (BP) is an inorganic compound composed of boron element and phosphorus element, which belongs to a semiconductor material. As early as 1891, French chemist Henri Moisan synthesized crystals of boron phosphate. Boron phosphide does not react with boiling concentrated acid or base solutions but may react with molten bases (e.g., sodium hydroxide) after preheating. Boron phosphide is resistant to oxidation up to 1000°C when exposed to air and reacts with chlorine gas around 500°C. The stability of the compound can be maintained under high pressure at 2500°C, while partial phosphorus will be lost by vacuum heating above 1100°C, resulting in B12p1 1.8, whose crystal structure is similar to that of boron carbide.
Due to the different production methods, boron phosphide has a red transparent, dark red transparent, black crystal or soft, brown amorphous material and so on. Chemically stable. Pure boron phosphide is almost transparent, with N-type crystals being orange-red, whereas P-type crystals are dark red.
Product Performance of Boron Phosphide BP Powder
Our Boron Phosphide BP Powder has high purity, narrow size distribution, high-temperature strength, high fracture strength, good chemical
resistance, good thermal shock resistance, low density and high hardness.
Boron phosphide does not react with boiling concentrated acid or alkali solution but can react with molten alkali (such as sodium hydroxide)
after preheating. Boron phosphide is resistant to oxidation below 1000 ° C when exposed to air, and can react with chlorine at about 500 ° C.
The compound can still be stable at 2500 ° C under high pressure, and some phosphorus will be lost by vacuum heating above 1100 ° C to
obtain B12P1.8, whose crystal structure is similar to boron carbide.
