Synthesis of nano-sized Leucite Glass-ceramics
Abstract
Objectives: The objectives of the study were to synthesize nano-sized leucite glass-ceramics.Methods: An aluminosilicate glass was ball milled using Attritor (AM) and high speed milling (HM) methods. A starting glass powder was wet ground in an Attritor Mill (1-S Lab, Union Process, USA) at 400 rpm with 5mm YTZ grinding media for 120mins and 2mm YTZ media for 120mins (AM4). A second Attritor milling regimen was 0.65mm YTZ media (90mins) and 0.40mm YTZ media for 480mins (AM9.5). The starting glass was also wet milled (Pulverisette P7, Fritsch, Germany) at 1000 rpm with 1mm YTZ for 30(HM0.5), 60(HM1), 120(HM2) and 240mins (HM4). Powders were subjected to crystallization heat treatments and characterised using Scanning Electron Microscopy and X-ray Diffraction. Ceramco-3 glass-ceramic was used as a control. Photomicrographs (AM:x2200, HM:x15000 magnification) were scanned using a light pen and image analysis software. Groups within milling methods were compared for significant differences (p<0.05) in median crystal size using a One Way ANOVA.Results: The median leucite crystal sizes (25%,75% percentiles, µm2) and significant differences (p<0.001) between groups are listed below.Glass-ceramic groupMedian Crystalsize (µm2)25%,75% PercentilesCrystallite numberStarting0.836 a0.589,1.190558AM40.345 b0.251,0.4571434AM9.50.140 c0.102,0.1963378HM0.50.085 d0.055,0.127790HM10.055 e0.038,0.0861076HM20.055 e0.036,0.0811315HM40.048 f0.030,0.0701718Ceramco-3 had a median leucite crystal size (25%,75% percentile) of 2.50(0.52,6.71) µm2. The experimental groups had significantly smaller median leucite particle sizes than Ceramco-3 (p<0.001). Tetragonal leucite was found in all the test groups. Attritor and high speed milling of glasses increased the number of crystallites and reduced the crystal size following heat treatments.Conclusions: Attritor and high speed milling of aluminosilicate glasses produced fine and nano-scale tetragonal leucite glass-ceramics with minimal matrix microcracking following crystallization heat treatments.
