Diborane Mixtures Gas mixture B2H6 / H2, N2, Ar, He Mixing ratio 1000ppm-30% The application of diborane is mainly reflected in the following aspects: Used as a doping source: Diborane is a P-type doping source used as a silicon material in semiconductor manufacturing and can be used in semiconductor production. Epitaxial growth: Diborane is used for epitaxial growth of silicon and germanium, which can improve the performance of semiconductors. Passivation: Diborane can be used for the passivation of semiconductor surfaces to reduce surface states and fixed charges and improve the reliability and stability of semiconductor devices. Diffusion: Diborane can be used in the diffusion process in semiconductors to form p-n junctions or to adjust the conductive type of semiconductor materials. Ion implantation: Diborane can also be used in the ion implantation process in semiconductors to change the electrical properties of semiconductors. In short, diborane is commonly used as a raw material for high-purity boron single crystals and decaborohydride. It can also be used as a doping source in the semiconductor industry to manufacture electronic devices. In semiconductor production, diborane can be used for processes such as epitaxial growth, passivation, diffusion, and ion implantation of silicon and germanium. In addition, diborane can also be used as a high-energy fuel for rockets and missiles. It has a high energy density, can exist stably in an oxygen free atmosphere, and is easy to store and transport. Ethylborane has broad application prospects in the fields of aerospace and aviation. In addition to the aforementioned fields, diborane can also be used in fields such as pharmaceuticals, metal welding, and organic synthesis. In the pharmaceutical field, diborane can be used to synthesize some drugs with special therapeutic effects. In the field of metal welding, ethylene borane can be used for the welding of metal materials, improving welding quality and efficiency. In the field of organic synthesis, diborane can be used to synthesize some polymer materials and other organic compounds. It should be noted that diborane has high toxicity and flammability, therefore corresponding safety measures need to be taken during storage and use.
Storage method
Store in a cool and well ventilated dedicated warehouse, implementing a “two person receiving and receiving, two person storage” system. Keep away from sparks and heat sources. The temperature of the warehouse shall not exceed 25 ℃, and the relative humidity shall not exceed 75%. It should be stored separately from oxidants, alkalis, halogens, and edible chemicals, and should not be mixed for storage. Using explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency response equipment for leaks.

First aid measures
Inhalation: Quickly remove from the scene to a place with fresh air. Maintain unobstructed respiratory tract. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention.
Fire extinguishing method: Cut off the gas source. If the gas source cannot be immediately cut off, it is not allowed to extinguish the burning gas. Spray water to cool the container, and if possible, move the container from the fire site to an open area. Fire extinguishing agent: carbon dioxide. Disable the water column and foam.
