Laser chemical vapor fine ceramic membrane was prepared

Of SiO. Only film resistivity and dielectric strength lower than plasma CVD deposition of sisNt film corrosion resistance than the plasma CVD is poor. With ArF laser photo 'shoot B: H. / NH. Mixture successfully stoichiometric BN film good, but only by thermal CVD method are rich B film. LCVD also obtained the TiN film with a metallic luster. LCVD obtained under low temperature and pressure in the diamond film with super-hard, insulation, wear resistance and high thermal conductivity and other characteristics, the above-mentioned dielectric film can have good wear resistance, can be widely used in various industrial sectors. Moreover, the Ta (OCHs) s / O: has prepared high dielectric strength of the TaO film. Table 4 LCVD synthesis of inorganic thin films. In the international arena in recent years LCVD developing very rapidly. But there are still many important issues unclear. If, LCVD a large number of chemical reaction and chemical equilibrium relationships, accurate determination of the reaction constants, molecular internal energy state of the incentive mechanism of the reaction process and other issues. LCVD suitable for industrial production and operation of automated, high temperature at low temperatures in the chemistry, is an excellent preparation of inorganic membrane technology. High efficiency, long life light source development, all kinds of special source of gas development,[link widoczny dla zalogowanych], process improvement means producers, experts and scholars to be actively involved in various fields, LCVD currently mainly used in the preparation of electronic devices, the application of other reported little, LCVD advantages , who has attracted researchers in many countries attached great importance to Greece as soon as possible the use of technology to develop a variety of fine LCVD ceramic membrane. �� 4 Chun Li Mao} gas cartridges should be scraped withdrawal photochemical preparation of a fine plug fall. --- _ Two to three references 1A. �� Johnsonetc, L �� CommlledchemicalProcessingofSurface,[link widoczny dla zalogowanych], 1984North - Holled19-35; 2Tanw13oetC, LaserPzoce ~ singofThinYdmsMkr0struct, Jr ~ 1987NewYo blood t 231 ~ 2493 Surface treatment Takai (Japan) 1990 �� vo1.41t? 8 ~ B04 Meguro and so on.

Sumitomo Metal Chun style clubs come up with a Ni C0 Taiwan-made powder beam Fortunately I J Arts. It is the cobalt ion acid aqueous solution into leather, at ~ 40'C temperature reaction of cobalt oxalate suspension, then add the nickel ion solution, while maintaining the temperature, can generate columnar crystals precipitate. wash, dry bath sediments, in non-oxidizing atmosphere at 400 ~ 700 �� thermal decomposition temperature of the sediments get together 30 to 95 Ni is a Ni alloy powder Feng C0. For example,[link widoczny dla zalogowanych], 23.6 liters CoCI {solution (Co170g / t) mA. leather to 100 liters of acid solution, the concentration of enzyme solution reform should meet all of C0 Shen ek a Ni ion, the prepared suspension, then add 3.1 liters NiCI2 solution (14gNi / t),[link widoczny dla zalogowanych], to fully precipitate . and then filter the precipitate, washing, drying, obtained the co-Ni leather 10.5kg salt. the oxalate heated to 620 ��, 2 hours in the decomposition of hydrogen can be obtained 3.8kgCo--NI units stacked powder. The tone of gold powder with Co88.9, Nil0.5%, and is the product of columnar crystals,[link widoczny dla zalogowanych], the long axis 5 ~ 1Opm, short axis is 0.5 ~ 1m. Liuguang Jun From
