Nano silicon boride takes us into the tiny world Nano silicon boride has specific optical, electrical, magnetic, thermal, acoustic, mechanical, chemical and biological properties, and are widely used in industrial and civilian fields. The continuous development of Nano silicon boride preparation technology will definitely have a significant impact on the traditional chemical industry and other industries. The impact will bring huge changes to people lives and bring human development into a new stage. Preparation method of Nano silicon boride: Gas-phase method: The gas-phase method refers to the method of directly using gas or through various means to transform substances into gas, causing them to undergo physical or chemical reactions in the gas state. And finally it condense and grow to form nanoparticles in the cooling process.
