Boron Carbide Overview

Boron Carbide Overview Boron carbide is an important special ceramic with many excellent properties. It was first discovered in 1858, and its hardness is second only to diamond and cubic boron nitride in nature. In particular, the near-constant high temperature hardness (>30GPa) is unmatched by other materials, so it has become an important member of the superhard material family. It is an important wear-resistant and high-hardness structural ceramic material among new ceramics and has been widely used in civil, aerospace and military [...]

Ultrathin Glass Overview

Ultrathin Glass Overview Ultrathin glass is also called ultra-thin electronic touch glass, with a thickness of 0.1-1.1 mm. Liquid crystal displays in the electronic information industry generally use 0.55-1.1 mm of float ultra-thin glass. Ultra-thin glass not only has the basic characteristics of glass such as high transparency, electrical insulation, heat resistance, chemical stability and gas resistance, but also has unique characteristics such as light weight, high temperature resistance, impact resistance, flexibility, etc. Therefore, it has broad application prospects in display panels, [...]

Introduction of graphite paper

What is graphite paper Graphite paper is made of high carbon flake graphite through chemical treatment and high temperature expansion rolling. Its appearance is smooth, without obvious bubbles, cracks, wrinkles, scratches, impurities and other defects. It is the base material for the manufacture of various graphite seals. It is widely used in dynamic and static sealing of machines, pipes, pumps and valves in electric power, petroleum, chemical, instrumentation, machinery, diamond and other industries. It is an ideal new sealing material to [...]

Meteorite, the source of the earth

Meteorite, the source of the earth Meteorites are solid fragments that originate from an object in outer space and fall to the ground. Such as comets, asteroids or meteoroids, which are left after passing through the atmosphere to the surface of a solid planet or moon. In this process, if it disintegrates or even becomes dust due to atmospheric friction and combustion, it is a meteor. Very few actually fall on the earth without becoming dust, and among these meteorites, there [...]

Introduction of Zirconia Ceramics

Introduction of Zirconia Ceramics Zirconia ceramic is white, yellow or gray when it contains impurities, generally contains HfO2, and is not easy to separate. There are three crystalline states of pure ZrO2 under normal pressure. The production of zirconia ceramics requires the preparation of powders with high purity, good dispersion properties, ultra-fine particles and narrow particle size distribution. There are many preparation methods for zirconia ultra-fine powder. The purification of zirconia mainly includes chlorination and thermal decomposition, alkali metal oxidative decomposition method, [...]

What is Piezoelectric Ceramics

What is Piezoelectric Ceramics Piezoelectric ceramics refer to polycrystals formed by mixing oxides (zirconia, lead oxide, titanium oxide, etc.) after high-temperature sintering and solid-phase reaction, and making them have piezoelectric effect through DC high-voltage polarization treatment. A general term for ferroelectric ceramics, it is a functional ceramic material that can convert mechanical energy and electrical energy into each other. Piezoelectric ceramics are a class of electronic ceramic materials with piezoelectric properties. The main difference from typical piezoelectric quartz crystals that do [...]

What is sapphire

What is sapphire Sapphire is a precious gemstone, a variety of the mineral corundum, consisting of aluminium oxide (α-Al2O3) with trace amounts of elements such as iron, titanium, chromium, vanadium, or magnesium.The name sapphire is derived from the Latin “saphirus” and the Greek “sapheiros”, both of which mean blue. It is typically blue, but natural “fancy” sapphires also occur in yellow, purple, orange, and green colors; “parti sapphires” show two or more colors. Red corundum stones also occur, but are called [...]
