Is a pure silver ring classified as an element, a compound, a homogeneous mixture, or a heterogeneous mixture? Explain. Is milk classified as a pure substance, a pure element, a homogenous mixture, or a heterogeneous mixture? A substance that can't be...
FIELD: diamond sintered materials and methods of their production. SUBSTANCE: diamond sintered material contains, vol.%: diamond, 50-99; binding phase, the balance. The latter consists of single or mixed phase from compound or mixture of at least one element selected from group including rare-...
A heater unit containing the reaction mixture, consisting of graphite (or some other carbon-containing substance) and a metal which promotes diamond synthesis, is placed in the compressible medium. After the necessary pressure has been generated, the mixture is heated by electric current to the ...
15(a): in the sp2, or graphitic, configuration, three of the four valence electrons lie in a plane, to which the final bond, now much weaker, is normal, Fig. 15(b). The so-called amorphous carbons, conventionally designated a-C, contain a mixture of sp2 and sp3 phases. Deposition ...
The present invention provides a diamond coated sintered body characterized by having a diamond film formed by a gas phase synthesis method on the surface of a sintered body obtained from a mixture of tungsten carbide and at least one compound selected from the group consisting of carbide and nit...
A method of forming a diamond film on a substrate wherein hydrogen, a hydrocarbon series gas, an inert gas, an organic compound series gas or a mixture of such gases is introduced into a vacuum vessel to contact a substrate and carbon is... Okamoto Koji c/o NISSIN ELECTRIC CO. LTD.,...
This mixture was heated to (T≈130∘C) for 4 hours under reflux. After cooling to room temperature, the acids were decanted and the diamonds were washed intensively with distilled water. In order to determine the presence of impurities in the investigated samples, particle induced X-ray ...
The benefit is twofold: A moth, which is inactive during the day, can significantly reduce eye glare and consequently become less visible to predators, while at the same time the moth’s corneal nipples can act as an optically matched layer between the facets of its compound eye and the sur...
2A or 2B, the compound containing the pre-determined impurity element is dissolved in the liquid diamond material 2a to prepare the mixture 2n, which is contained in the vessel 1n. FIG. 2A shows a case wherein the compound to be dissolved comprises powder, and FIG. 2B shows a case where...
1-301864 describes the formation of thin film having maximum surface roughness of 200 Å or less composed of a mixture of diamond crystals, graphite crystals and amorphous carbon under the formation conditions of an organic gas concentration of 3 mol % or higher, and use thereof for a ...
