June 25 Hydrofluoric acid Commodity Index was 59.44, unchanged from yesterday, the highest point in the cycle compared with 100.00 points (2011-09-01) decreased by 40.56%, compared with January 19, 2016 the lowest point of 54.10 points, up 9.87 percent. (Note: refers to the period since 2011-09-01).

A market overview: Hydrofluoric acid market as a whole is stable, but the market is slightly less, although manufacturers offer a whole stable, but the market turnover declined slightly. Operating rate is still around Liucheng, the national market, this weekend the price 6550 yuan / ton, down 1.54%. 

The market analysis: Product: This week anhydrous hydrofluoric acid market downward trend, especially in the South-end market price decline, the current situation in the case of downstream yet to recover, and started to increase, adequate supply, MERCOSUR is a serious bid, the price decline; In contrast, Early North MERCOSUR better than the market upward, so now the market remains stable north, the downstream refrigeration industry started relatively stable. Shandong region offer range of 6500-7700 yuan / ton factory, the main area to the price of 6500-6900 yuan / ton, the mainstream offer East interval 6400-6900 yuan / ton factory, in central China offer range of 6450-6800 yuan / ton factory.

Chain: upstream fluorite powder market was less than the month, the price is more than a correction, such as Jiangxi province transaction price down 30 yuan / ton; downstream refrigeration industry into the off-season, but by the impact of the G20 summit, a serious shortage of supply, rose sharply this week situation, but later prices will enter callback operating rate of decline.

The market outlook forecast: Currently hydrofluoric acid market is relatively stable, the overall more bearish, market confidence was also inadequate, while the downstream refrigeration industry into the off-season, analysts believe that the business community hydrofluoric acid hydrofluoric acid under short-term market or competitive pressures MERCOSUR downturn is likely to continue, Northern markets affected by the overall impact of the decline was smaller.

Some study report that on the influence of particle size, time and temperature on the kinetics – quantified by X-ray diffraction – of the selective extraction of Al from the ternary layered transition metal carbide, Ti3AlC2, when powders of the latter are immersed in hydrofluoric acid. Transmission and scanning electron microscopy, energy-dispersive X-ray spectroscopy and thermogravimetric analysis were also used to characterize the resulting powders. Increasing the temperature and immersion times, and decreasing the Ti3AlC2 particle size, led to faster conversion of Ti3AlC2 to its 2-D Ti3C2 counterpart. Arch-shaped edges at the ends of some Ti3C2 layers resembled graphene, corroborating the single-sheet structure of exfoliated Ti3C2. The removal of water and/or OH surface groups from Ti3C2 using drying in vacuum was also attempted.
