Future Prediction Of Tin Powder

wallpapers News 2020-12-24
Tin powder is gray-green powder with a melting point of 231.88°C. The boiling point is 2270°C. The relative density is 7.28. It is soluble in concentrated hydrochloric acid, sulfuric acid, aqua regia, concentrated nitric acid and hot caustic alkali solution, and slowly dissolves in cold dilute hydrochloric acid, dilute nitric acid and hot dilute sulfuric acid. Cold caustic alkali solution dissolves more slowly in acetic acid. It is stable in air, but tin powder is easier to oxidize, especially in moist air. Materials used in the electronics industry, used as high-purity reagents.
Global forecast
With the release of the growth rate of the semiconductor industry, electronic solder still dominates half of the downstream demand for tin. In the second quarter of 2011, due to the impact of the Japanese earthquake, the growth rate of the global electronics industry slowed down. However, considering the impact of the resumption cycle of electronic materials and equipment in Japan and the backward transmission of orders, we believe that the third quarter will start The global electronics manufacturing industry will see recovery growth at the same time, and will appear faster than expected.

According to our global PCB circuit board shipments, it is expected that in the next 5 years, it will maintain or exceed a 5% compound annual growth rate, reaching 690 million square meters. Our standard PCB circuit board size conversion is about 228 It can be calculated based on the 8-9.5 grams tin consumption per standard-size PCB circuit board. By 2015, the global demand for electronic solder to draw tin is about 206,000 tons, and the CAGR reaches 12.5%.
Driven by the photovoltaic industry
As the photovoltaic industry continues to explode in the future, photovoltaic ribbons have become the fastest growing downstream demand side in the soldering field. The world’s new photovoltaic installed capacity could exceed 30GW in 2012, 87GW in 2015, and 293GW in 2020. Based on this, it is estimated that the global new photovoltaic installed capacity from 2011 to 2015 is expected to maintain a compound growth rate of 40%. Demand will also increase simultaneously.
According to our calculations, every 100MW of photovoltaic cells requires about 50 tons of photovoltaic ribbons. Based on the tin content of 20-25%, it requires 10-12.5 tons of tin metal. The current demand for tin metal for photovoltaic ribbons is only 1550-1938 tons. However, with the rapid increase of newly installed photovoltaic capacity (assuming a compound annual growth rate of 30%), the demand for tin for photovoltaic ribbons will increase to 29312-36640 tons by 2020. Photovoltaic ribbons will undoubtedly be a sub-industry with fast downstream demand for tin.
