In recent years, silicon carbide product quality has achieved rapid development and improvement of production equipment, technology, research and innovation as well as regeneration waste silicon carbide are making a valuable contribution to the quality of domestic products of international quality to follow its example, so as to make the domestic products on the international market has powerful, but due to price competition anti - dumping, due to the lack of independent intellectual property rights of refusal to show embarrassment, is hindered by the domestic products on the international market, the competitiveness of the high end of the lift is also difficult.
