Essential oil of mentha asiatica boriss. From Uzbekistan
(1997)
Water-distilled essential oil of Mentha asiatica was analyzed by GC/MS. Thirty seven compounds were characterized representing 97% of the total components detected. The major constituents of the oil were trans-piperitone ...

Electrocoagulation for oil-water emulsion treatment
(Taylor & Francis Inc, 1997)
An attempt has been made to remove oil from synthetic and actual oily wastes by an electrochemical method using either iron or aluminum reactors. The effects of applied potential i.e direct current, reactor material and ...
The effect of heat-treatment on the performance of sub-micron SiCp-reinforced alpha-beta sialon composites .1. Preparation of agglomerate-free starting powders
(Elsevier Sci LTD, 1997)
In order to prepare good-quality, dense, SiCp-reinforced alpha-beta sialon composites by hot-pressing, a technique was developed to prevent agglomeration of the SiC grains during powder processing. For this purpose, the ...
The driving force for ??ß transformation in rare earth ? sialon ceramics
(1997)
In-situ ??ß sialon transformation in rare earth sialon systems, which occurs when dense ?- and ?/ß-sialon samples are heat-treated at temperatures in the range 1300-1600°C was first observed five years ago, and has generated ...
The effect of heat-treatment on the performance of sub-micron SiCp-reinforced alpha-beta sialon composites .2. Heat-treatment studies
(Elsevier Sci LTD, 1997)
The effects of heat-treatment on alpha --> beta sialon transformation in dense, agglomerate-free Ln-sialon/SiCp(Ln=Nd,Yb) composites are reported. The stability of the alpha-sialon phase is not only dependent on the ...
Interphase boundaries between hexagonal boron nitride and beta silicon nitride in silicon nitride-silicon carbide particulate composites
(1997)
Inter phase boundaries between hexagonal boron nitride and Q-Si3N4 in hot isostatically pressed Si3N4-SiC particulate composites, in which boron nitride appears as a trace contaminant, have been examined using high resolution ...
Optimization and improvement of sialon ceramics with new heat treatment techniques
(1997)
Sialons are of interest for use as engineering materials for high temperature (>1000°C) applications becuase they retain good mechanical properties at these temperatures, whereas competing metallic materials are weak and ...
