Traditions of ancient writers attribute some discoveries in these lines to India or Persia, or other Asiatic countries, but as to whether any of these countries contributed in any important way to the development of Egyptian chemical knowledge, or whether at some time these countries learned their arts from Egypt, we cannot safely determine from such tradition. It is quite certain that both in China and in India the chemistry of the metals and alloys, methods of dyeing and the use of certain chemicals in medicine were practiced at ancient periods, but their chronology is diffi-...

For the purpose of making relative measurements of the bulk condutivity in paper, a pressure of 2000 psi (13.8 MPa) was chosen. At that pressure, most paper samples typically compres 5 /tm, from 70 (im to 65 /W16)- As can be concluded from the discussion below, the results of measurements at 2000 psi (13-8 MPa) are in good agreement with the Ga-In liquid alloy method. Samples were contacted on both sides with Ga-In over an area of 0.8 cm2 and were placed in the pressure conductivity cell. A nominal pressure of 3-2 psi (22 kPa) was applied to the electrodes. 

A1(NH3)6](BH4)3 have been reported. Those borohydrides might be useful for controlling the thermodynamic stabilities, similar to the conventional alloying method for hydrogen storage materials. ... 

In the 2- or 3-alloy method, the alloys are usually separately milled to their respective optimal particle sizes. They are then mixed in dry form using tumble blenders. Mixing coarse, individually pre-ground powders followed by a final hall-milling of the blend is also done.

The study of these materials started with the formation of nanometer-size grains with an agglomerated microstructure, by melt-spinning and mechanical alloying methods. In this section, we will initially discuss the development of both methods, and also explain recent studies of nanocomposite materials in the sense mentioned above. 

The consolidation of a SiC nanopowder synthesized by the mechanical alloying method was subsequently accomplished by SPS at 1700 °C for 10min under an applied pressure of 40 MPa, without using any sintering additives. The SiC sintered compact with a relative density of 98% consisted of nanosized particles smaller than 100 nm. The mechanical properties of sintered compacts were close to those of reference samples sintered with boron and carbon as the sintering additives [210].

Sodium fusion may be performed using either sodium metal or a commercially available sodium-lead alloy, which contains nine parts lead and one part sodium. For safety reasons, we recommend using the sodium-lead alloy method because the alloy is easier to handle than is sodium metal and poses less potential danger during hydrolysis. 

Historically, various investigators in Europe have used hydrochloric acid-px>tassium dichromate solutions for testing the exfoliation susceptibility of all types of aluminum alloys. An example is the Russian Stanchtid GOST 9.904-82, Aluminium Alloys Methods of Accelerated Exfohation Corrosion Testing [22]. It should be noted, however, that hexavalent chromium (Cr ) solutions are considered undesirable for health and environmental considerations and have been prohibited in some countries. 

The alloy method is used in the manufacture of tetramethyl- and tetraethyllead, antiknock additives to petrol (p. 100). Similarly bismuth aryls were first made by Michaelis in 1877 by the reaction of powdered bismuth-sodium alloy with aryl halides,...

The targets of our development are as follows. The first point is to maintain the advantages of PPS such as its thermal properties, mechanical properties, etc. The second point is to improve the brittleness of PPS using the polymer alloy method.
