Quartz Glass: An Ideal Medium for Nuclear Waste Reprocessing

Nuclear waste reprocessing to remove irradiated graphite involves a catalytic treatment using specially designed quartz glass assemblies.                 Typical British graphite moderated high-temperature nuclear reactors each contain about 2,000 tonnes of graphite in large blocks that becomes irradiated with the carbon-14 isotope. The purpose of the graphite is…

Fused Silica in Millimetre Wave Technology

Fused silica in silicon-based technology is set to enable next-generation 5G gadgets. Smartphones and tablets are a product of 4G, otherwise known as wireless digital, networks. This has enabled users to download files containing full-length films in less than 10 minutes, even though the file size would average about one gigabyte. The electronics industry is…

Aluminum Nitride Replacing Beryllium Oxide in Substrates

Safety concerns have led to aluminum nitride being used as a substitute for beryllium oxide in high-power electronics. High-power microelectronic devices and applications have always needed materials with a high thermal conductivity. Beryllium oxide fitted this need for the last few decades and became the electronic sector’s most desirable material for use in substrates. Its…

Boron Nitride Ceramics Outperform Carbon Nanotubes

  Nanotube cylinders of boron nitride are nearly as strong as their carbon counterparts, but they also do more. Boron nitride in its hexagonal form has a structure that is similar to carbon graphite. And like carbon, a sheet of the boron material that has a thickness of just one atom can be rolled into…

Technical Ceramics Increase Jet Engine Thrust

TECHNICAL CERAMICS Composite materials made of technical ceramics are becoming a major ingredient in jet engine and power-generation technology components. Think of a material that is as tough as a metal, not as brittle as a ceramic and that can survive a temperature of 1316 degrees Celsius. The answer is silicon carbide – not the…

Alumina Removes Water Contaminants

Water treatment technology based on activated alumina can provide long-term safe water supplies in highly contaminated areas.  Is your tap water safe to drink? That was a difficult question to answer if you lived in the City of Andrews in West Texas. Alumina has made the city’s water supply safe to drink, but it took…

Fused Silica Fibres in Mid-Infrared Range Lasers

The use of hollow-core fused silica fibres has assisted the development of lasers in the mid-infrared spectral range.                 The mid-infrared part of the electromagnetic spectrum ranges between wavelengths of between 2 and 5 microns (micrometres). This is the wavelength range of radiation emitted by heart-seeking missiles, active…

The History of Scientific Glassware

Today’s scientific glassware is a product of over 6,000 years of glass-making.               Glass occurs naturally in the mouths of volcanoes. It’s a dark material called obsidian that early man used for the tops of spears. Archaeologists believe that glass made by man dates back to around 4,000 BC,…
