Title: Precipitation of nanocrystals in glasses by electron irradiation: An alternative path to form glass ceramics?

Abstract

This letter demonstrates an alternative method to form gallium silicate glass ceramics using high-energy electron irradiation. Compared with glass ceramics obtained from the conventional thermal treatment method, the distribution and crystal sizes of the precipitated Ga{sub 2}O{sub 3} nanoparticles are the same. An advantage of this method is that the spatial distribution of the precipitated nanoparticles can be easily controlled. However, optically active dopants Ni{sup 2+} ions do not participate in the precipitation during electron irradiation.

  • Synthesis of borophosphosilicate glasses and glass-ceramics was accomplished via a modified oxide sol-precipitation process (MOSP). Thermal properties of the dried precipitates were analyzed. Heat treatment of the precipitates crystallized the boron phosphate phase. The microstructure of sintered samples was characterized using electron microscopy, and the dielectric properties were measured. Dielectric measurements indicate that the sintered glass-ceramics possess dielectric constants less than 4.0 and dissipation factors less than 0.001 at a frequency of 1 MHz. 25 refs., 9 figs., 2 tabs.

  • The nanocrystallization behavior of 25K{sub 2}O-25Nb{sub 2}O{sub 5}-(50-x)GeO{sub 2}-xSiO{sub 2} glasses with x=0,25,and50 (i.e., KNb(Ge,Si)O{sub 5} glasses) and the chemical etching behavior of transparent nanocrystallized glass fibers have been examined. All glasses show nanocrystallization, and the degree of transparency of the glasses studied depends on the heat treatment temperature. Transparent nanocrystallized glasses can be obtained if the glasses are heat treated at the first crystallization peak temperature. Transparent nanocrystallized glass fibers with a diameter of about 100{mu}m in 25K{sub 2}O-25Nb{sub 2}O{sub 5}-50GeO{sub 2} are fabricated, and fibers with sharpened tips (e.g., the taper length is about 450{mu}m and the tipmore » angle is about 12{sup o}) are obtained using a meniscus chemical etching method, in which etching solutions of 10wt%-HF/hexane and 10M-NaOH/hexane are used. Although the tip (aperture size) has not a nanoscaled size, the present study suggests that KNb(Ge,Si)O{sub 5} nanocrystallized glass fibers have a potential for new near-field optical fiber probes with high refractive indices of around n=1.8 and high dielectric constants of around {epsilon}=58 (1kHz, room temperature)« less
  • The presence of BaCl2 nanocrystals and the crystallographic phase that they adopt controls the optical behavior of fluorochlorozirconate glass-ceramics. We have used in situ X-ray diffraction heating experiments and ex situ transmission electron microscopy to follow the BaCl2 nanocrystal nucleation and growth processes as a function of heating rate and isothermal hold temperature. The BaCl2 nanocrystals nucleate with the hexagonal crystal structure and grow as spherical particles to a size of similar to 10 to 20nm. They then undergo a structural transformation to the orthorhombic phase and their shape changes to rounded disks, with diameters ranging from 150 to 250nm,more » and thicknesses ranging from 80 to 120nm. The change in size results from Ostwald ripening of the hexagonal BaCl2 nanocrystals to form the orthorhombic BaCl2 nanocrystals.« less
