Our April issue features details on advanced materials such as ceramic matrix composites and piezoelectric ceramics, among many others. Be sure to check it out!
Three critical factors determine the success of any new material technology: material properties, design practices (i.e., how to properly use and apply the material) and a supply chain that can produce the material at specification.
Piezoelectricity is electric polarization produced by mechanical strain in certain crystals, the polarization being proportional to the amount of strain and changing sign with it.
Refractory minerals are used to improve the performance of refractories products by imparting properties such as strength, protection from chemical and physical attack, and slag resistance.
Silicon nitride (Si3N4) and silicon carbide (SiC) systems have been used in industry for many years, and both systems have a range of properties that make them excellent choices in a number of demanding environments.
Specialty ceramic cements are directly relevant to our lives, but we rarely notice their presence. The important physical characteristics of these cements include the capacity to deal with temperature changes varying from ambient temperature up to 3000°F (1650°C) and higher, depending on the specific case.
Advanced ceramics have found their place in a number of applications, largely due to their superior mechanical properties.
Carbon is one of the earliest known elements. It was used by the Egyptians and Sumerians in the form of charcoal around 3750 B.C. for the reduction of copper, zinc, and tin ores in the manufacture of bronze.
The country is promoting the development of high-quality, energy-efficient unshaped refractories.
“The preissuance submission provision in the America Invents Act aims to bring the most relevant prior art to the examiner’s attention as early as possible during prosecution to enhance examination effectiveness and efficiency,” says Undersecretary of Commerce for Intellectual Property and Director of the U.S. Patent and Trademark Office (USPTO) David Kappos.
