Refractory titanium dioxide

Refractory titanium dioxide ■ basic outline in order to improve the performance of sintered refractory products, lower sintering temperatures often drop 入纳米 titanium dioxide in refractories, TiO2 and corundum have similar lattice constants, is also a variable price oxides in a reducing atmosphere in, Ti4 + is reduced to Ti3 +, thus dissolved in the corundum, and in part a reducing atmosphere, Al2O3 and TiO2 Al2O3-TiO2 can form solid container body. In the article the sintering process, due to price changes the role of the corundum crystals internally generated lattice defects, lattice activation, promote sintering. 1600 degrees, titanium dioxide in the solid alumina capacity (by mass) up to 1%, so 0.5% was added titanium dioxide, can reduce the sintering temperature 150-200 degrees, but little effect on the fire resistance products. ■ Technical indicators Project quality standards Model VK-T25N Appearance loose white powder crystal Rutile content% ≥ 99.9% * 15867120050 nm 30-50nm particle surface area (m2 / g) 40-60 ■ main purposes: refractory products. ■ Add capacity: 0.5-1% ■ Packing: 25kg / Bag Hangzhou Wan Jing New Material Co.: 0571-85351209,15867120050 QQ: 1980779123,1789379397 Website: http: //www.veking.cn
