Thermal Atomic Layer Etching of Aluminum Oxide (Al2O3 ...

Apr 09, 2021· Thermal atomic layer etching (ALEt) of amorphous Al2O3 was performed by alternate exposures of niobium pentafluoride (NbF5) and carbon tetrachloride (CCl4). The ALEt of Al2O3 is observed at temperatures from 380 to 460 °C. The etched thickness and the etch rate were determined using spectroscopic ellipsometry and verified by X-ray reflectivity. The maximum etch rate of about 1.4 …

Bentonite - Wikipedia

Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent swelling clay consisting mostly of montmorillonite usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. Bentonite beds are white or pale blue or green in fresh exposures, turning to a cream color and then yellow, red, or brown as the exposure is weathered ...

Feb 05, 2021· In a study by Kou et al., the adsorption of dodecylamine (DDA) on a quartz surface was measured as a function of DDA concentration at two different pH values using the QCM-D technique. The adsorbed mass obtained in such study was approximately 40 (at pH 6) to 100 ng/cm 2 (at pH 9.5) for a DDA concentration of 13 g/L.

Steel Glossary | Glossary of Terms | Platts

The usual measure is a dry metric tonne unit (excluding moisture content), although dry long ton units are sometimes used. A unit of iron is 1% of iron, and a typical current price is 75 cents per dry metric tonne unit (see Dry metric tonne unit). So, at this price for ore assaying 63% iron, a tonne sells for $0.75x63 = US$47.25 (excluding ...

Gyratory Crusher - an overview | ScienceDirect Topics

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are ...
