Silicon Nitride Ceramic:
After long-term struggle and openness to the world, China’s plastics industry has formed a relatively complete industrial system and has become a basic material industry that goes hand in hand with steel, cement, and wood. As a new type of material, its application fields have far exceeded the above three. Since these materials entered the 21st century, China’s plastics industry has made remarkable achievements and achieved a historic leap. As one of the pillar industries of the light industry, the plastic industry has maintained a growth rate of more than 10% in recent years. While maintaining a relatively fast development rate, its economic benefits have also been improved. The total output value of enterprises above designated size in the plastic products industry ranks third among the 19 main industries of light industry, with a product sales rate of 97.8%, which is higher than the average level of the light industry. Judging from the production of synthetic resin, plastic machinery and plastic products, they all show the strong development momentum of China's plastics industry.From January to December 2007, China's plastic products enterprises achieved a total industrial output value of RMB 80,181,565,700, an increase of 27.06% over the same period of the previous year; from January to October 2008, China's plastic products enterprises achieved a total industrial output value of RMB 788,006,448 thousand, which was more than A year-on-year increase of 22.16%.China is a major producer of plastic raw materials, and it is also a huge consumer of plastic products. According to industry authoritative statistics, as of 2013, there were 13,699 domestic plastic products enterprises of a certain size. The national output of plastic products was 61,886,600 tons, a year-on-year increase of 8.02%. Among them, the output of plastic film products was 10.893 million tons; the output of plastic daily necessities was 4.716 million tons; the output of plastic artificial leather and synthetic leather products was 3.47 million tons; the output of fiber reinforced plastic products was 2.5986 million tons; the output of foam plastic products was 1.465 million tons.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
