/C2H2 ratio for diamond synthesis in oxyacetylene flames can be theoretically predicted. When the substrate temperature is between 1000 K and 1250 K, the corresponding O2/C2H2 ratio range is about between 0.8 and 1.1. The suitable range of substrate temperature is widest for O2/C2H2 ratio close to unity and is narrowed rapidly when the flow ratio deviates from unity.
