erosion resistant
4.Phytolith plays an important role in the study of paleobotany and paleo-environment because of its small, high yield, and its ability of anti-erosion and high-temperature resistant.
6.The erosion resistances of 5 kinds refractories:electric cast quartz bricks,natural white afrodite, sintered pure alumina, AZS bricks and zircon bricks, in molten glass have been tested by the way of static immersion method, the results obtained show that alumina bricks are suitable to be used as furnace lining for irradiation - resistant insulation glass fiber production.
7.The following conclusions were dlawn: as compared with the concretemade of Portland cement, the concrete made ofslag cement was more resistant to acid rainl thecoordinate erosion of H+ and SO:-- reduced thestrength of concrete, and the reduction was asecondary linear function of both CaO loses andthe ratio of SO, content to CaO content;
