The phase-separation glasses with composition of Na2 O(9. 0) B2 O3 (25.0)- SiO2 (66.0) ( in mole ratio ) were leached with hydrochloric acid, and porous glasses
The samples of the GeS2- Ga2 S3- CdS pseudo-ternary glassy system were prepared by conventional melt-quenching techniques. The microstructure of the GeS2- Ga2 S
The characteristic of autogenous shrinkage ( AS ) and its effect on high strength lightweight aggregate concrete (HSLAC) were studied. The experimental results
Needle-like hydroxyapatite crystals were synthesized by homogeneous precipitation method with water-soluble calcium salts and phosphates.The work focuses on the
By means of an inherent elevated-temperature of poured liquid steel, a Ti-G-30wt% Fe preform, which was pre-placed in a mould cavity, was directly ignited and a
