ABSTRACT

The R2O–CaO–MgO–Al2O3–SiO2–Fe2O3 glass ceramics was prepared using granite wastes and Fe2O3. The effect of Fe2O3 on crystallisation and properties of glass ceramics was studied. Results show that the crystalline phases were Fe2TiO5 and K(NaCa)Mg5Si8O22F2 when the content of Fe2O3 was low. The main crystalline phase was Fe1.5Ti0.5O3 when the content of Fe2O3 was high. With the increase of Fe2O3, the crystal size of K(NaCa)Mg5Si8O22F2 reduced and the atomic ratio of Si to Mg increased. The colour of sample varied from greyish green to black with different additions of Fe2O3. The flexural strength with a maxim (101.02 MPa) when the content of Fe2O3 was 4.7 mol-%. Given the low cost of granite wastes and Fe2O3, this new type of black glass ceramics is expected to meet the increasing demand from the market of building decoration due to its excellent properties.

Fe2O3对R2O-CaO-MgO-Al2O3-SiO2-Fe2O3微晶玻璃结晶和性能的影响

摘要

R 2 O-CaO-MgO-Al 2 O 3 -SiO 2 -Fe 2 O 3玻璃陶瓷是用花岗岩废料和Fe 2 O 3制备的。研究了Fe 2 O 3对微晶玻璃结晶和性能的影响。结果表明,当Fe 2 O 3含量较低时,晶相为Fe 2 TiO 5和K(NaCa)Mg 5 Si 8 O 22 F 2。主晶相为 Fe 1.5 Ti 0.5ø 3当Fe的含量2 ö 3高。随着Fe 2 O 3的增加,K(NaCa)Mg 5 Si 8 O 22 F 2的晶体尺寸减小,Si与Mg的原子比增大。Fe 2 O 3 的添加量不同,样品的颜色从灰绿色到黑色不等。当Fe 2 O 3的含量为4.7 mol-%时,弯曲强度最大(101.02 MPa)。鉴于花岗岩废料和 Fe 2 O 3 的低成本,这种新型黑色微晶玻璃以其优异的性能有望满足建筑装饰市场日益增长的需求。
