Anatase Thin Films on Glass from the Chemical Vapor .

Thin (50−500 nm) films of TiO2 may be deposited on glass substrates by the atmospheric pressure chemical vapor deposition (APCVD) reaction of TiCl4 with ethyl acetate at 400−600 °C. The TiO2 films are exclusively in the form of anatase, as established by Raman microscopy and glancing angle X-ray diffraction. X-ray photoelectron spectroscopy gave a 1:2 Ti:O ratio with Ti 2p3/2 at 458.6 eV .

How It Works: Vapor Deposition Process | Pure Glass .

OVD-formed glass allows very tight control of the chemicals that go into the vapor and, in turn, the glass. The result is some of the purest glass imaginable. Pure silica glass, either with or without intentionally small amounts of dopants, is also able to withstand vast temperature changes with virtually no expansion or contraction.

Shop Rotary Evaporators & Rotovaps [Price Matched]

What are rotary evaporators? A rotary evaporator (or rotavap or rotovap) uses precise engineering to effectively remove solvents from a sample using evaporation. Most rotovaps make use of a vacuum and pressure control monitor to precisely control pressure within your system, increasing evaporation efficiency.. In many commercial labs, these machines need to be running around-the-clock without .

Chemical vapor deposition - Wikipedia

Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.. In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit.
