Main Differences Between Special And Traditional Ceramic Materials

Differences	Special Ceramic Materials	Traditional Ceramic Materials
Raw Materials	Synthetic "selected highly quality raw materials" (oxides and non-oxides).	Natural minerals,such as clay, quartz,feldspar,etc.
Shaping process	Pressing, hot pressure casting, injection, film rolling, isostatic pressing.	Grouting,mostly plastic molding
Firing process	Advanced methods such as vacuum sintering, protective atmosphere sintering, hot pressing and hot isostatic pressing are widely used in the temperature range of 1200 ~ 2200 ℃ . Mainly fueled by electricity, oil and gas.	Generally below 1350 ℃, Mainly fueled by coal, oil and gas.
Properties	Emphasis on inner quality, it has excellent physical and chemical properties, high-strength , high-hardness, wear resistance, corrosion resistance, high temperature resistance, thermal shock resistance,and excellent performance in heat, light, sound, electricity, magnetism, chemistry, biology, etc.	Emphasis on outward appearance
Additional processing	Generally, additional processing (cutting, drilling, grinding and polishing) is required.	Generally,no additiona processing required.
Purpose	Has wide range of valuable uses in petroleum, chemical, steel, electronics, textile and automobile industries. Also used in advanced technology industries, such as aerospace, nuclear and military.	Cooking utensils, tableware and handicrafts.
