  • Silica - Fused Silica (Silicon Dioxide)
    Article - 2 May 2002
    Fused silica is an amorphous grade of silica known for its low thermal expansion and thermal shock resistance. It is made by melting high purity silica sands and has uses in refractories, investment...
  • Silica - Colloidal Silica (Silicon Dioxide)
    Article - 2 May 2002
    Colloidal silica consists of a stable suspension of tiny silica particles. It has many applications such as refractories, investment casting, abrasives, surfactants, high temperature binders etc
  • Superalloys for Coal Fired Power Generation
    Article - 11 Mar 2002
    Superalloys are emerging as a viable alternative to ceramic filters for clean burning coal power generators. The possibility of creating thin filters with high surface area and limited susceptibility...
  • Tantalum - An Overview
    Article - 23 Jan 2002
    Tantalum is a rare metal with a grey-blue appearance. It is found in about 15% of the world’s pegmatites. Tantalum has several properties that currently make it a valuable commodity.
  • Mullite - An Introduction
    Article - 15 Oct 2001
    Mullites main uses are in refractories and ceramic bodies where it contributes properties such as thermal shock resistance, volume stability and hot strength. It is an aluminosilicate material rarely...
  • Kyanite
    Article - 15 Oct 2001
    Kyanite is an aluminosilicate used predmoninantly for refractories and ceramic bodies. It consists nominally of 60% Al2O3 and 40% SiO2. Al larger irreversible volume expansion makes it useful in...
  • Mullite - An Introduction
    Article - 3 Oct 2001
    Mullite is the mineralogical name for the only chemically stable intermediate phase in the SiO2–Al2O3 system. The mineral rarely occurs in its natural form, and can be found on the Isle of Mull off...
  • Nickel Chrome Alloys - Properties and Applications
    Article - 24 Sep 2001
    Nickel/chromium alloys have excellent oxidation resistance, wear-resistance and high-temperature properties. Typical applications include heating elements and thermocouples.
  • Ceramic Foams - An Alternative to RCFs
    Article - 24 Sep 2001
    Porous ceramic foams have emerged as a viable alternative to refractory ceramic fibres since they were classified as carcinogenic. Hi-Por is a ceramic foam that has similar properties to FCFs without...
  • Molybdenum (Mo) - Properties, Applications
    Article - 29 Jul 2001
    Molybdenum is silvery-white, very hard refractory metal, however, it is softer and more ductile than tungsten and is readily worked or drawn into very fine wire. Primary uses are as an alloying...

The Current State of the Global Semiconductor Market

The global semiconductor market has entered an exciting period. Demand for chip technology is both driving the industry as well as hindering it, with current chip shortages predicted to last for some time. Current trends will likely shape the future of the industry, which is set to continue to show

How are Graphene Batteries Made?

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
