  • Method of preparing a multimodal cubic boron nitride powder
    Patent number: 10196314
    Abstract: Multi-step milling processes to prepare cBN composite powder forms a first powder mixture by adding a binder and a first cBN component, mills the first powder mixture for a first time period, combines a second cBN component with the milled first powder mixture to form a second powder mixture, and mills the second powder mixture for a second time period (less than the first time period) to form the cBN composite powder. A ratio of the D50 value of the second cBN component to the D50 value of the first cBN component is at least 3.0. Two-step milling with different milling times for the two cBN component fractions controls the amount of mill debris in the cBN composite powder mixture. Further processing of the cBN composite powder under HPHT conditions forms a cBN-based ceramic with an average value of a cBN particle free diameter of less than 2.0 microns.

  • Photochromic glass with sharp cutoff
    Patent number: 10150692
    Abstract: A photochromic glass that includes a base glass and a photochromic agent is described. The base glass is a modified boroaluminosilicate glass and the photochromic agent is a nanocrystalline cuprous halide phase. The photochromic glass exhibits a sharp cutoff in the UV or short wavelength visible portion of the spectrum along with an absorption band at longer wavelengths in the visible. The nanocrystalline cuprous halide phase includes Cu2+, which provides states within the bandgap of the cuprous halide that permit the glass to absorb visible light. Absorption of visible light drives a photochromic transition without compromising the sharp cutoff. The nanocrystalline cuprous halide phase may optionally include Ag.
