Chemical Properties of Real and Ideal Glass Surfaces These differences are due to high temperature surface chemical phenomena which occur during the formation and cooling of a melt glass surface, as well as to surface chemical reactions under ambient conditions. This is in contrast to an ‘ideal’ glass surface whose composition and structure are ident

The Relationships between Powder Properties, Sintered Microstructures and Optical Properties of Tranps of powder properties and several process parameters are described. The crucial features which lead to > 99.5% of the theoretical density in a highly translucent body have been identified as: (1) surface area, (2) agglomerate size, (3) a chemical composition free of multivalent and/or light-absorb

Polymers and Polymer Precursor Characterization limit defining the number of repeat units for a molecule to be regarded as polymeric. However polymers usually have molecular weights (MW) greater than about 5000 g/mol or an average of more than 100 repeat units per molecule; and unlike low MW compounds, polymers consist of a distribution of chain

An Advanced Technique for Characterization of Polymer Materials by Wide Angle X-Ray Scatteringng the requisite data at greatly enhanced speed, without sacrificing accuracy, and which allows immediate data analysis by a digital computer. The WAXS system combines a position-sensitive X-ray detector with a 65 kbyte microcomputer capable of operation as a multichannel analyzer. The data acquisit
