By heating and pressing the raw materials at high temperature to form them, the density of the materials is enhanced, the microstructure is optimized, the strength and toughness are improved, and due to the high-quality corrosion resistance, high temperature resistance, aesthetics, hygiene, and good ductility of the materials, they are widely used in many fields such as construction, decoration, food processing, medical equipment, chemicals, automotive industry, energy, electronic equipment, etc.
