Turbulent premixed oxygen‐acetylene flames have been used to synthesize polycrystalline diamond films on molybdenum substrates at temperatures ranging from 500 to 1300 °C and facetted single crystals on mm‐sized natural diamond substrates at tem

Turbulence in the flame of an oxyacetylene torch used for diamond growth was studied with mass spectrometry and dark‐field shadowgraphy. H2, CO, N2, and C2H2 were observed in both laminar and turbulent diamond growing flames, while O2, CO2, and H2O

OH radical desorption over a polycrystalline Pt foil exposed to mixtures of H{sub 2}, O{sub 2}, and H{sub 2}O for surface temperatures between 1000 and 1800 K was measured by laser-induced fluorescence (LIF) and used to determine the elementary steps

Diamond has been grown epitaxially on 1.5 mm diameter, natural diamond seed crystals at temperatures of 1200–1300 °C in a premixed, turbulent oxyacetylene flame. During a typical 1 h deposition, a polyhedral-shaped single crystal was observed to g

Raman scattering and photoluminescence spectroscopies have been used to characterize polycrystalline diamond films deposited on molybdenum substrates by laminar and turbulent premixed oxygen-acetylene flames in air. Samples deposited under laminar fl
