摘要

硅铝系陶瓷纤维具有优良的性能，在冶金、石油化工等领域得到了广泛应用。但是传统的硅铝系陶瓷纤维矿物粉尘能与生物细胞产生较强的生物化学作用，这不但危害了人体健康，而且对环境也造成一定的污染。研究表明：传统纤维(持久性矿物纤维)对人体存在潜在的致癌危险，可溶性陶瓷纤维(非持久性纤维)则没有致癌性。

本文通过采用CaO-SiO2系统中添加P2O5来调节纤维的性能，使用感应炉对原料的熔融获得初步的样品。通过对样品的研究了解了热处理对纤维的析晶性能的影响等。还进一步研究了玻璃态纤维中存在晶相物质。

关键词：耐火纤维 生物可溶 析晶性能 应用前景 制备

ABSTRACT

The use of fiber materials can largely economize energy sources, because silicon-aluminium system fiber materials possess many good peorfmrnaces . It has extensive appliance in metallugry , atomic energy industry . But many traditional silicon-aluminium system ceramic fiber`s mineral power can produce bio-chemical actions with the cells in biological body , which not only can do harm to people`s

health , but also can do certain harm to natural environment . Studies show that durable mineral fiber has a potential danger to cause cancer to people , but not nondurable mineral fiber.

In this paper , the bio-soluble fibers were studied by adding P2O5 to the CaO-SiO2 system to adjust the performance of the fiber . And using the induction furnace melting of raw materials to obtain a preliminary sample . By studying the affect of heat treatment to the crystallization performance of the fiber . The crystalline phases present in the fiber were also been studied.

Key Words: Refractory fiber . Bio-soluble . Crystallization . Application prospects . Manufacture
