**5. Conclusion**

The characteristics of synthesis nanomaterials using HVPG has been described and reported in the present study. The details aspect of the synthesis and the sample of the results of the synthesis nanomaterial also presented. It is shown that the HVPG can be used to synthesis various type of nanomaterials with the following advantages: excellent pureness ratio, free of external impurity during synthesis process, simple procedure and setup, environmentally friendly, and used recycle material (quartz tube) that previously used as the heating components. Since the application of nanomaterials can be found in very wide aspects, the synthesis process of nanomaterials using HVPG can be an alternative method. The future trend as shown in the present study ensure the sustainability of the synthesis nanomaterial without compromising with the environment and related to human healthy aspect.
