Nano sam-ples were grown under three different temperature conditions in CVD(Chemical Vapor Deposition) method.

This paper reviewed the recent development of the intermetallic compounds,focusing on the preparation techniques including self-propagating high-temperature synthesis(SHS),mechanical alloying(MA),melting and casting technology and vapor deposition.

In this paper several substrate surface activation methods for electroforming compos- ite material molds are briefly introduced,including traditional substrate surface activation,vapor deposition activation,DBD activation,photochemical activation and auto-catalytic activation,etc.

Employing the physical vapor deposition method,Bi2O3 powder was heated to 1050 ℃ at normal pressure in a horizontal tube furnace with the protection of argon gas and oxygen,and then cooled and deposited naturally.

Silica coating was prepared by atmospheric pressure chemical vapor deposition taking HP40 steel plate as substrate,tetraethyl orthosilicate as silica source,and air as carrier gas and diluent.

Single-walled carbon nanotubes have been prepared from coal gas by catalytic chemical vapor deposition technique with ferrocene as catalyst, and electrochemistry analysis was carried on supercapacitance using nanotubes as electrodes.

　Carbon nanotubes (CNTs) is prepared by means of chemical vapor deposition (CVD) method.

Well-aligned open-ended multi-walled carbon nanotube (MWCNT) arrays were prepared via chemical vapor deposition (CVD) method in porous anodic aluminum oxide (AAO) templates without depositing any transition metals as catalyst.

In recent year, the helical carbon fibers are preparation by chemical vapor deposition method(CVD), which commercial acetylene as the carbon source, a nickel as catalyst, a sulfur compound as impurity, reaction temperature at 700～850℃.

In the present work, different shaped carbon nanotubes were produced by the general CVD and the template method at different temperature (600 ℃,700 ℃) with the reaction gas of acetylene.
