基础玻璃配比对白云鄂博尾矿—粉煤灰微晶玻璃的影响研究
摘要
微晶玻璃具有优良的力学、热学、电学和化学性能。在国防、航空航天、电子、化学、生物、医学、机械工程和建筑等领域得到了广泛应用。
本课题以白云鄂博尾矿与粉煤灰为主要原料,添加少量化工原料。研究不同基础成分对微晶玻璃的性能的影响,研究基础成分含量变化对所制备的矿渣微晶玻璃熔制高温粘度、核化机理、晶化过程中的相组成的变化规律;研究基础成分含量变化对所制备的矿渣微晶玻璃力学性能及抗腐蚀性的影响规律及作用机理;探索矿渣微晶玻璃的相组成和微晶组织与基础成分含量之间的关系。
本课题主要研究CaO/MgO 比、CaO/Al2O3比和SiO2/ CaO比变化对微晶玻璃各项性能的影响。通过对微晶玻璃试样的各项性能分析,最终确定合理的玻璃配方及制备工艺。

The ratio of the base glass tailings Baiyun Obo – fly ash glass
Abstract
The glass-ceramic with excellent mechanical, thermal, electrical and chemical properties. Has been widely applied in the field of defense, aerospace, electronics, chemistry, biology, medicine, mechanical engineering and construction.
This experiment take Baiyun Obo tailings and fly ash as main raw material, add a little of chemical raw materials. Researching the influence of different position of glass-ceramics on performance, and transform position of Slag glass ceramics to research the regular of melting temperature viscosity, nuclear mechanism and the altering position in crystallization process; Researching influential regular and mechanism of mechanical properties and corrosion resistance by changing basic ingredients of slag glass ceramics; explore the relationship between slag glass-ceramic position and crystalline microstructure and basic ingredients.
The subject mainly studies CaO / MgO ratio, CaO/Al2O3 ratio and SiO2 / CaO ratio on performance of the glass-ceramic. Analyze by the each performance of glass-ceramic sample, and ultimately make the glass formulation and preparation process.
Keywords: glass-ceramic; tailings; fly ash; position
