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 is higher than an inflatable heat for 10 minutes, maybe because the oven is controlled amount of oxygen 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.
