In processing ceramic glaze, it boasts wide range of application,sound opalescence and fluidity as well as good wear resistance and whiteness and low radioactivity, thus cannot be affected by firing conditions while can prominently improve the combining property between clay and glaze and increase glaze surface's hardness, which also explain its popularity in ceramic production.

硅酸锆之所以在陶瓷生产中得以广泛应用，还应为其化学稳定性好，粒度细，分布合理，白度高，放射性低，因而不受陶瓷烧成气氛的影响，且能显著改善陶瓷的坯釉结合性能，提高陶瓷釉面硬度。

We are also indebted to Pierre Curie for basic research in the field of radioactivity, which has been carried out either alone, in collaboration with his pupils.

Results The choroid plexus, hypophysis, area postrema and pineal body, namely, circumventricular organs and ependyma as well as pia mater layers were stained by the HRP reaction products.The HRP reaction products were observed in the tissue space of membrane mucosa nasi, around the fila olfactoria and venules, and within the venules under the light microscopy and electron microscopy, also. Scintillation count showed that the radioactivity of the CVOs was higher than that of the background. The radioautography showed that the scattered grains of silver existed within the cells of neurocyte layer also.

结果 在脑室周围器官及脑室周围室管膜、软脑膜层有HRP反应产物的聚集，在鼻中隔的鼻粘膜下组织间隙、嗅丝周围间隙及静脉周围和管腔内也可见到HRP反应产物；液闪计数显示，大白鼠的脉络丛、脑垂体、最后区、松果体等脑室周围器官放射性活度明显高于本底；放射自显影显示大白鼠脑组织神经层细胞内有散在分布的银颗粒。
