Microsoft Corp. released its own tablet computer Surface in Los Angeles on the 18th. Microsoft's trial of the horizontal board computer market is considered to be a major strategic adjustment to increase competition with Apple and other rivals. On the same day, Microsoft CEO Steve Ballmer said at a press conference in Hollywood that Surface is a "tool that can make your passion appear on the surface." There are two Surface tablet computers released by Microsoft. One of them is similar to Apple's iPad, but it is thinner and more heavy. It is only 9.3 mm thick, weighs 676 grams, and has a screen size of 10.6 inches. The other is a "thick", 13.5 mm thick and weighs 903 grams, similar to the "Ultrabook" released by Intel. Both Surface tablets are equipped with Microsoft's own Windows operating system. Previously, Microsoft has been relying on hardware manufacturers to manufacture and sell products that are preinstalled with operating systems and charge fees. The industry commented that Microsoft has launched its own tablet computer with Windows operating system, and it is intended to compete for the market share of tablet PCs, thus further enhancing the market competitiveness. At present, the tablet PC market is not only the Apple iPad, but also many products using the Android operating system.

Zirconium silica ash is an amorphous, powdery, high-purity silica obtained through the oxidation of silica vapour discharged from the flue and collected by a specially designed dust collector during the smelting of desilicated zirconium in our company. The particle size is a few hundredths of the average particle size of cement. The specific surface area is 15 -27 m2/g, with strong surface activity.It is mainly used in cement or concrete admixture to improve the performance of cement or concrete, wear-resistant, scour-resistant, corrosion-resistant, penetration-resistant, frost-resistant, early-strength special concrete for dams, large reservoirs, hydropower, harbour wharves, railway bridges, highways, airfield runways, tunnels and ultra-high-rise buildings and other projects. At the same time, micro-silica powder can also be used in the production of refractory materials and ceramic products, to improve the strength and durability of the product; used in paints, coatings, resins, rubber and other polymer materials filler, can play a role in improving the comprehensive performance of the material.
