Under the conditions of depressed manufacturing industry, tungsten market also enters normalization ordinary. Tungsten raw material capacity stays in the constant high level. With the application of tungsten waste, end market lowers its dependency on tungsten raw material. Cost of heavy mining is increasing, it results in the irreconcilable conflicts of tungsten market.

Ammonium metatungstate price affecting factors is mainly related to raw material price, below are the analysis of those factors:

1.Tungsten raw material producing capacity is relatively at high level, supply of tungsten concentrate and APT overdue actually demanding which results in the unbalance of supply-demand relationship, it affects tungsten raw material price directly.

2.Tungsten mine cost directly affects price, heavy mining based on state-owned enterprise has high cost; medium and small mine is of lower cost. So tungsten concentrate of low price is sometimes active in the market.

3.Enterprise property of tungsten mine has effects on price as well. More than 50% tungsten concentrate originated from state enterprise tungsten mine. State-owned enterprise actively supports market place. When the price is too low, they will refuse to sell the product to protect rare metal source.

4.Capacity of tungsten concentrate is relatively centralized, more than 55% is from eight major tungsten enterprises. Since last year, three conference of the enterprises also save the market in a certain degree.

5.Through out a year, tungsten market will go through the spring supply and summer break. After spring festival, there is once confused of market, most tungsten raw material companies are reluctant to sell and hold on to see the trend of market. It results in the market’s short supply and increases of price. Summer break is often in July and August, most European countries takes summer break and stops production. The demanding is rare during this period.

6.China Tungsten Industry Association and Ganzhou Tungsten Industry Association has effects on tungsten market as well. When the market is unstable, they will preserve interests of members.

7.Market guidance price of Ganzhou Tungsten Industry Association and China Minmetals Group publicized every month have effect on market price.

8.State Reserve Bureau purchasing and storage of tungsten concentrate directly affects price. Since 2013, purchasing and storage for 5 times of tungsten concentrate, 3 of them have succeeded and affects tungsten raw material price.

9.Fanya Metal Exchange purchased a lot of APT since 2014, over 30000 tons of APT is purchased in 2014. But the price keeps sliding due to the increase of capacity. The stop of purchasing and returned of goods in the market in the beginning of 2015 causes tungsten price slumps in 2015. There is still 29651 tons of APT is stocked in Fanya, the potential effect can not be ignored.

10.Tungsten concentrate trade situation. When price difference is more than profit, capita flows into tungsten concentrate market. The trade operation will also affect market. When price of tungsten concentrate is less than manufacturing cost, traders purchase a lot as inventory then sell it at high price. The sliding of price in June,2016 is the classical operation method of traders.

Besides the above factors, environmental protecting policy, resource tax reform, weather condition in main factory, main stream big enterprises shut down, etc. are all the reasons that will affect price.

It said that China Aerospace Science and Technology Corporation (CASTC) will begin to develop a high-tech aircraft, which is more efficient than the retired space shuttle. It uses a variety of power to take off from the general airport and fly straight into orbit. This power-combination space shuttle will use the combined cycle engine turbojet or turbofan engines allow the aircraft to take off from runway level. As the speed increased, it has been adjusted as the supersonic combustion ramjet. During the combustion ramjet engine set-up phase, the supersonic space shuttle will enter a hypersonic flight in "near space" office, which located at 20~100 km above sea level. Finally, the supersonic space shuttle will fly to the "near space" by using its rocket engine, then fly into the orbit. This space shuttle will not allow trained personnel easier access to space, as compared with the space launch vehicles, space shuttle accelerate its flatness, which will reduce the astronauts when it is subjected to be taken off to physical strain. This means that a version of the space shuttle can be used in space travel. At such a high temperature environment requires very high temperatures resistant metals like tungsten alloy, tungsten, copper, titanium and other materials, it is apparent the rapid progress of tungsten alloy, tungsten, copper, titanium and other materials technology will enable China to have the ability to support research and development in the field of materials technology such as ultra-high performance supersonic space shuttle.

At present, China has already had a variety of advanced solid and liquid fuels in space rockets. Even China disadvantaged in the history of the turbine engine technology, that won’t be a problem. For CASTC, the biggest challenge may lie in the integration of all relevant components into a propulsion package, so as to build a strong structure to withstand various tests such as re-entry.
