Silicon Nitride Ceramic:
The profitability of Silicon Nitride Ceramics has declined month by month. For example, demand for Silicon Nitride Ceramic Plunger used in high-pressure pumps has dropped significantly, resulting in lower sales and profitability for manufacturers in the industry. In the first half of 2013, the metallurgical industry achieved a profit of 73.69 billion yuan, a year-on-year increase of 13.7%, of which the ferrous metal smelting and rolling processing industry achieved a profit of 45.44 billion yuan, a year-on-year increase of 22.7%. From January to May, the profitability of key large and medium-sized steel companies was far worse than the overall level of the industry, and showed a monthly decline. Although the profit increased by 34%, it was only 2.8 billion yuan, and the sales profit rate was 0.19%. In the month of May, 86 key large and medium-sized iron and steel enterprises only realized profits of 150 million yuan, which was a decline for five consecutive months. Among them, 34 made losses, with losses as high as 40%. The growth rate of fixed asset investment in the silicon nitride ceramic industry has dropped significantly. From January to June 2013, the investment in fixed assets in the iron and steel industry was 303.5 billion yuan, an increase of 4.3% year-on-year, of which investment in ferrous metal smelting and rolling was 235.6 billion yuan, an increase of 3.3% year-on-year, and a decrease of 6.1 percentage points from the same period in 2012; The selected investment was 67.9 billion yuan, an increase of 7.8% year-on-year, and the growth rate dropped sharply by 15 percentage points.
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.
