Silicon Nitride Ceramics:
The output of Silicon Nitride Ceramic Standard Parts hit the highest level in history. From January to June 2013, the country’s cumulative production of crude steel was 390 million tons, a year-on-year increase of 7.4%, and the growth rate was 5.6 percentage points higher than the same period in 2012. In the first six months, the average daily crude steel output was 2.154 million tons, equivalent to an annual crude steel output of 786 million tons. Among them, it reached a record high of 2.208 million tons in February. Although it dropped from March to June, it still remained at a relatively high level of more than 2.1 million tons. In terms of provinces and regions, from January to June, the crude steel output of Hebei and Jiangsu increased by 6.8% and 13.2% respectively year-on-year. The combined output of the two provinces accounted for 42.4% of the national increase of 26.94 million tons. In addition, Shanxi, Liaoning, Provinces such as Henan and Yunnan have also increased production by more than 1 million tons. In terms of enterprise types, from January to June, the crude steel output of key large and medium-sized iron and steel enterprises increased by 5.5% year-on-year, 2 percentage points lower than the national average increase, but 60% of the increase in production still came from key large and medium-sized iron and steel enterprises. Steel prices are running low. From January to June 2013, the overall performance of the domestic steel market was sluggish. With the large release of crude steel production capacity, market supply and demand have fallen into a state of imbalance, and steel prices have entered a downward channel and have been weakly down for more than four months. As of July 26, 2013, the steel price index fell to 100.48 points, which was lower than 6.6 points at the beginning of the year. The prices of the eight steel products under the key statistics of the Iron and Steel Association have all declined to varying degrees from the beginning of the year, with an average drop of 5.7%. In terms of varieties, the prices of construction wire rod and rebar, which account for a large proportion of my country's steel output, fell 4.9% and 6.7%, respectively, and the prices of medium and heavy plates and hot-rolled coils fell 5.7% and 9.7%, respectively.
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.
