烧结制度对BeO陶瓷性能的影响

本文分别采用一次烧成与二次烧成两种烧成方式,利用现有的氧化铍造粒料,制作标准的测试件在不同的烧成温度下烧结成瓷。对不同烧结方式、烧结温度的陶瓷产品的热导率（25,100℃）、体积密度、平均晶粒度进行检测,研究不同烧结制度对氧化铍陶瓷热导率、体积密度、平均晶粒度的影响。     

Factors affecting phenol adsorption on clay-solidified grouting curtain

Batch experiments were conducted to study the adsorption of phenol on clay-solidified grouting curtain (CSGC) and the effects of contact time,pH and adsorbent concentration on the adsorption were investigated.Under the experimental conditions used,2 d was adequate to determine the equilibrium of phenol adsorption onto CSGC.The amount of phenol adsorbed by CSGC from an initial concentration of 100mg/L was found to be 8.4mg/g.The adsorption process includes particle diffusion and liquid film diffusion,and the...
