  • Fused quartz tubing for pharmaceutical packaging
    Patent number: 9399000
    Abstract: A high silica glass composition comprising about 92 to about 99.9999 wt. % SiO2 and from about 0.0001 to about 8 wt. % of at least one dopant selected from Al2O3, CeO2, TiO2, La2O3, Y2O3, Nd2O3, other rare earth oxides, and mixtures of two or more thereof. The glass composition has a working point temperature ranging from 600 to 2,000° C. These compositions exhibit stability similar to pure fused quartz, but have a moderate working temperature to enable cost effective fabrication of pharmaceutical packages. The glass is particularly useful as a packaging material for pharmaceutical applications, such as, for example pre-filled syringes, ampoules and vials.

  • Method for making high purity metal oxide particles and materials made thereof
    Patent number: 9249028
    Abstract: The present invention is directed to a method of making metal oxide and mixed metal oxide particles. The method includes treating a mixture formed from a metal source, such as metal alkoxide, a surfactant, and a first alcohol in an aqueous media at a very high metal oxide yield. The mixture is reacted using a catalyst to form metal oxide particles having a desired particle size in said mixture. By washing the particles with an aprotic solvent, the residual carbon content of the particles can be significantly reduced. The method is particularly suitable for forming silica particles. The metal oxide particles can then be heat treated to form synthetic fused metal oxides such as, for example, synthetic fused silica.
