日前,国家“七五”扶贫项目、河北省硅线石厂选矿开发研究通过专家鉴定验收。硅线石是一种无水铝硅酸盐矿物,是新型高线耐火材料和生产高铝制品的重要材料。其制品广泛用于温度变化剧烈或使用条件比较苛刻的窑炉衬体部位,在国外已广泛用于钢铁、玻璃、陶瓷、机械、化工等行业。 Recently, the national “Seventh Five-Year” poverty alleviation project and the development of silicalite plant in Hebei Province have been examined and approved by experts. Sillimanite is an anhydrous aluminum silicate mineral and is an important material for new high-line refractories and high-alumina products. Its products are widely used in kiln linings where the temperature changes drastically or in harsh conditions of use. They have been widely used in steel, glass, ceramics, machinery, and chemical industries.
