When observed from the graph shows a comparison of the sample, it was found that, the thermal annealing furnace at a temperature of 500 ° C. The amount of titanium at higher sample Spark, then blowing hot air for 10 minutes, possibly due to the oven with a volume control. Oxygen causes oxide less than blowing hot air. In normal weather conditions, which do not have a closed system like the heating oven. It has a high percentage of oxygen and results in a lower percentage of titanium heating stove.
