Diborane(B2H6) is a colorless, unstable, highly toxic flammable gas with a sickly-sweet odor. In pure form, it must be cooled to below 0˚C for shipment. When diluted, however, stability is improved and it is therefore shipped as a mixture under high pressure in steel cylinders. Diborane(B2H6) can be diluted with argon, helium, hydrogen or nitrogen in order to provide concentrations less than 100%. Using diborane in this form can add an additional degree of control to the process, particularly when relatively small amounts of boron are to be deposited. Boron atom is a p-type dopant for epitaxial silicon. Boron is introduced to silicon wafer by diffusion implantation techniques. Mixtures are analyzed prior to shipment to ensure that the concentration is in the range requested. Diborane mixtures are prepared as ordered. Concentrations other than those listed below are available upon request.

1. What's your product price?
Because each gas price depends on your quantity and purity requirements, it is difficult to give a fixed price. If you are interested in some gases, please provide your details. I can offer you an offer.

2. What's the min order?
Different products with different MOQ, please do not hesitate to tell us your needs

3. What's your payment term?
50% T/T deposit, 50% T/T against B/L copy or 100% Irrevocable L/C at sight

4. All the cylinders can recycle?
 Usually seamless steel cylinder can recycle to use in 30 years. The disposable cylinder is only for use one time.when you ordered our cylinders, next time, you can send back the cylinders to fill gas again. You just need to tell us before you export. We will handle all the import customs clearance formalities.

5. Is there any cautions to use gas cylinders?
1) The use and testing of gas cylinder shall be subject to “Safety inspection regulations for gas cylinders” issued by State Bureau of Quality and Technical Supervision. 
2) The gas cylinder shall away from heat and sunlight exposure. The distance from fire should be no less than 10 meter. And it is prohibited to hit the cylinders. 
3) It is prohibited to use fire to heat the valve if it was frozen. 
4) The nozzle of the gas cylinder was strictly prohibited from oil contamination 
5) The gas in the cylinder cannot be entirely exhausted, it would be better to remain not less than 0.040 MPa residual pressure 
6) The filling pressure of gas cylinder cannot exceed the prescribed pressure.
