Product Description Product DescriptionSilane is a colorless, reacting with air and can cause choking gas. The gas is usually caused by contact with air, it will burn and emit a very strong white amorphous silica smoke. The primary health hazards it is its spontaneous combustion flame can cause severe thermal burns, severe or even fatal if. If the flame or high temperature in a portion of the silane cylinder before the cylinder valve will start to explode. If the discharge pressure is too high or too fast silane can cause lag explosion. If there is no spontaneous combustion of silane leaks can be very dangerous, do not close. Staff dealing with emergency situations and personal protective equipment must be adapted to the circumstances of the fire protection. Do not try to cut off gas supply before extinguishing. Silane gas is colorless, toxic, flammable gas with a garlic flavor annoying.Physical propertieProjectAttributeCharacterColorless and smells disgusting garlicGas density(g/mL,25°C)1.44Relative density of steam(g/mL,air=1)1.1Melting point(oC)-185Boiling point(oC, atmospheric pressure)-111.9Boiling point(oC,760mmHg)-112Heat of evaporation(KJ/mol)12.5Heat of fusion(KJ/mol)0.67Generate heat(KJ/mol)32.6Specific heat capacity(KJ/(kg·K),25oC)1.335Critical temperature(oC)-3.5Critical pressure(MPa)4.864Typical technical data ItemImpurities(ppm)SiH4 purity(%) ≥99.9999 Ar≤0.05Chlorosilane≤0.15Si2H6≤0.5He≤1CO≤0.05O2≤0.05N2≤1H2≤20CO2≤0.05CH4≤0.05C≤0.2SiH2Cl2≤0.5CH3Si≤0.5Metals≤0.03Our high quality SiH4 gas can be use in electronics industry a variety of material making and widely used in solar cells etc.ApplicationSeveral industrial and medical applications exist for silane and functionalized silanes. For instance, silanes are used as coupling agents to adhere fibers such as glass fibers and carbon fibers to certain polymer matrices, stabilizing the composite material. In other words, silane coats the glass fibers to create better adhesion to the polymer matrix. They can also be used to couple a bio-inert layer on a titanium implant. Other applications include water repellents, masonry protection, control of graffiti, applying polycrystalline silicon layers on silicon wafers when manufacturing semiconductors, and sealants. The semiconductor industry used about 300 metric tons per year of silane in the late 1990s. More recently, a growth in low-cost solar photovoltaic module manufacturing has led to substantial consumption of silane for depositing hydrogenated amorphous silicon (a-Si:H) on glass and other substrates like metal and plastic. The PECVD process is relatively inefficient at materials utilization with approximately 85% of the silane being wasted. To reduce that waste and the ecological footprint of a-Si:H-based solar cells further several recycling efforts have been developed.Silane is also used in supersonic combustion ramjets to initiate combustion in the compressed air stream. As it can burn using carbon dioxide as an oxidizer it is a candidate fuel for engines operating on Mars. Since this reaction has some byproducts which are solid (silicon dioxide and carbon) it is applicable only to liquid-fuel rockets (with liquid carbon dioxide), ramjets, or other reaction engines.Related ProductsMain products:1.
