Trichlorosilane, also known as trichlorosilane or chloroform, is a colorless liquid that is easily volatile and deliquescent. In the air, trichlorosilane reacts to produce hydrogen chloride gas. It is an important raw material for the synthesis of organic silane and alkyl, aryl, and organic functional group chlorosilane, as well as for the production of semiconductor silicon and monocrystalline silicon. When trichlorosilane reacts strongly with oxidants, it can ignite or explode when exposed to open flames, high temperatures, or water. Its specific gravity is 1.35, boiling point is 31.8 ℃, and flash point is -13.9 ℃. In production, trichlorosilane is mainly used for the production of polycrystalline silicon and is an important raw material for industries such as photovoltaic, semiconductor, and cermet. The downstream application field of polycrystalline silicon is mainly the photovoltaic industry. With the continuous development of photovoltaic technology, the application field of photovoltaic power generation is also more extensive, thus driving the growth of demand for trichlorosilane. At the same time, trichlorosilane is also the most basic monomer of organic silane coupling agents, which can be crosslinked with almost any material. Therefore, it plays an important role and occupies an indispensable position in various fields such as solar cells, glass fibers, reinforced resin fiber protection films, and so on. It should be noted that trichlorosilane has acute toxicity, with a half lethal dose of 1030 mg/kg for oral intake in rats and 1500 mg/m3/2 hours for inhalation in mice. At the same time, it is also a flammable and explosive substance that can ignite or explode when exposed to open flames, high temperatures, or water. When producing or using trichlorosilane, safety precautions should be taken and corresponding protective measures should be taken. Electronic grade trichlorosilane is mainly used in silicon epitaxial sheet and silicon carbide industry. In the semiconductor industry, electronic grade trichlorosilane is mainly used in the manufacture of polysilicon and silane coupling agents. Among them, the application fields of polysilicon are solar cells, semiconductors and cermet. Silane coupling agent is mainly used in the fields of surface treatment agent, inorganic filler plastic, tackifier, sealant, special rubber bonding accelerator and so on. In addition, electronic grade trichlorosilane is also used to make raw materials for optical fiber, which is an essential basic material in information technology and optical fiber communication technology.
Storage precautions:
Store in a cool, dry, and well ventilated warehouse. Keep away from sparks and heat sources. The temperature of the warehouse should not exceed 25 ℃. The packaging must be sealed and protected from moisture. It should be stored separately from oxidants, acids, alkalis, etc. 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 and suitable storage materials.

Transportation precautions:
During transportation, transportation vehicles should be equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency response equipment. The exhaust pipe of the vehicle transporting this product must have a flame retardant device. During transportation, it is necessary to ensure that the container does not leak, collapse, fall, or be damaged. It is strictly prohibited to mix and transport oxidants, acids, alkalis, edible chemicals, etc. During transportation, it is necessary to prevent exposure to sunlight, rain, and high temperatures. During a stopover, stay away from sparks and heat sources. Transport vehicles and ships must be dry and have good rainproof facilities. The vehicle should be thoroughly cleaned after transportation. It is prohibited to slide during railway transportation.
