What is Tetramethylsilane?
Tetramethylsilane is chemically represented as C4H12Si and is a colorless and transparent organic liquid. The main characteristic of this compound is its four methyl groups, which enable tetramethylsilane to exhibit unique properties in organic chemical reactions. In terms of physical properties, tetramethylsilane has a boiling point between 26 and 28 ℃ and a density of 0.648g/cm ³， The refractive index is 1.358 (20 ℃). The flash point of this compound is -27.2 ℃, indicating that it does not self ignite under standard conditions. Its saturated vapor pressure is 80.3kPa at 20 ℃, while the critical pressure is 2.81MPa. Tetramethylsilane exhibits good solubility and can dissolve in most organic solvents, such as ether. However, it is not soluble in water and cold concentrated sulfuric acid. The main uses of tetramethylsilane are as reagents, aviation fuels, solvents, and nuclear magnetic resonance reagents. In addition, it has important applications in semiconductor chip manufacturing. Due to its four methyl groups, it can be used in various organic chemical reactions and has a wide range of applications. It should be noted that tetramethylsilane can burn under certain conditions and may form explosive mixtures when mixed with air. Therefore, when operating and using tetramethylsilane, relevant safety regulations and operating procedures should be strictly followed to prevent danger from occurring Tetramethylsilane has a wide range of applications in the electronics industry, especially in the semiconductor manufacturing process. Tetramethylsilane is a high-purity electronic chemical that can be used in the semiconductor industry. As a precursor, chemical vapor deposition (CVD) is used to prepare thin films, which can be used in etching hard masks, deposition of carbon-doped silicon-containing films, deposition of silicon carbide films and other fields. These applications mainly involve processes such as cleaning, etching and deposition during semiconductor manufacturing.
Precautions for the use of tetramethylsilane include
Closed operation, local ventilation. Operators must undergo specialized training and strictly adhere to operating procedures.
It is recommended that operators wear a filtered gas mask (full face mask), self-contained breathing apparatus or ventilated breathing apparatus, chemical safety goggles, anti-static work clothes, and rubber oil resistant gloves.
Keep away from sparks and heat sources, and smoking is strictly prohibited in the workplace.
Use explosion-proof ventilation systems and equipment.
Prevent vapor leakage into the air of the workplace.
Avoid contact with oxidants, acids, and alkalis.
When transporting, it is necessary to load and unload gently to prevent damage to the packaging and containers.
Equip corresponding types and quantities of firefighting equipment and emergency response equipment for leaks.
Empty containers may have residual harmful substances.
When storing tetramethylsilane, the following precautions should also be taken:
Store in a cool, dry, and well ventilated warehouse.
Keep away from sparks and heat sources.
The temperature of the warehouse should not exceed 20 ℃.
The packaging must be sealed and protected from moisture.
It should be stored separately from oxidants, acids, and alkalis, and mixed storage should be avoided.
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.
