4、根据下面内容，回答题：
人类使用玻璃已有4500多年的历史了，而且早在公元100年前就用它吹制瓶子和其他器皿。如今，玻璃的功能和用途越来越多，新的“家族”也在不断扩大。
玻璃是一种非结晶、无机透明的物质。常规的玻璃一般用天然氧化物如钠或硼硅酸盐制作。它具有坚硬、耐化学侵蚀、有强度、能导光和透视性强等特点。更有发展前途的是它还能同不同的元素相熔合，在处理过程中改变化学结构，从而产生新的功能和特性。为了扩大玻璃的应用范围和功能，近年来，研究者们一直在努力开发利用玻璃的这种特性，采用非常规技术来加工成新型玻璃，使其具备金属、塑料和陶瓷都没有的功能。其中有一个令人振奋的开发成果就是结晶玻璃。这项发明打破了玻璃是非结晶结构的传统定义。
结晶玻璃的应用在于制作人造骨。日本电气硝子株式会社新开发研制出的一种名为CERABONEA—W的人造骨，就是采用这种材料。常规的人造骨头是用金属、陶瓷，或者一种非常类似天然骨头的材料磷灰石(钙磷酸盐)制成。可惜这些材料都不够理想。金属和陶瓷产品有强度，但与天然骨头不能较好地嫁植。磷灰石嫁植效果好，但强度不够。结晶玻璃解决了这些难题。这种材料由30％的玻璃和70％含有磷灰石及硅灰石(钙硅酸盐)的水晶所组成。植入人体后，它所渗出的钙与磷酸能促进新的骨组织在真骨与人造骨之间生长。同时硅灰石晶体发挥了比真的骨头还结实的强度作用。目前日本厂家已将这种产品投放市场，并开始了新的开发和医疗试验，以使这种材料用于加固脊椎骨或替代失去的骨头。
