    摘要: A glass ceramic precursor glass and a glass ceramic having low levels of rhodium and a method of controlling the amount of rhodium in such glasses and glass ceramics. The precursor glass and glass ceramic contain from about 1 ppm to about 10 ppm and, in certain embodiments, from about 1 ppm to about 6 ppm rhodium. The method of controlling of reducing rhodium dissolution from a rhodium-containing material such as, for example, an alloy into a glass melt comprises controlling and/or lowering the partial pressure of oxygen at the rhodium-containing vessel/glass interface by imposing a high humidity condition around the external (non-glass-contact) surface of the rhodium-containing material. The lower concentration of rhodium minimizes its coloring effect on the white color of the glass ceramic.

    摘要: Apparatus for cleaning contaminated aggregate comprising: at least one channel arranged in use to receive a liquid containing contaminated aggregate; and first and second banks or groups of at least one jet.The first bank or group of jets is arranged to direct pressurised fluid at the contaminated aggregate in order to agitate the contaminated aggregate against a surface thereby promoting separation of cleaned aggregate from contaminated aggregate. The second bank or group of jets is arranged to direct and/or urge the cleaned aggregate to a drainage outlet.

    摘要: A process for making silica-based glass includes: (a) forming a glass precursor melt that includes glass network formers and glass network modifiers, the glass precursor melt having a viscosity of not more than 30 Pa·s at 1300 C., and (b) refining the glass precursor melt. Either or both steps (a) and (b) can include stirring and/or be carried out under reduced pressure to enhance refining. The refined glass precursor melt preferably is mixed with additional materials including silica (SiO2) to form a silica-based glass melt.
