Application of Quartz Glass in High-tech Field

Application of Quartz Glass in High-tech Field Quartz glass has excellent mechanical, thermal, optical and chemical properties, and is widely used in semiconductors, optics, optical fibers, photovoltaics, electric light sources, aerospace and other fields. Quartz glass is an industrial technical glass composed of a single component of silicon dioxide. Since silicon dioxide is an atomic crystal and there is a covalent bond between Si-O, quartz glass has strong temperature resistance and stable chemical properties; The chemical bond energy between Si-O is [...]

Magnetic Ceramics – Ferrite

Magnetic Ceramics – Ferrite Ferrite is a composite oxide mainly composed of iron oxide and other iron or rare earth oxides. It are mostly semiconductors, and their resistivity is much higher than that of general metal magnetic materials, and they have the advantage of small eddy current loss. In the field of high frequency and microwave technology, such as radar technology, communication technology, space technology, electronic computer and so on, it has been widely used. Classification of ferrites Cutting of Ferrite At present, [...]

Quartz crucible: an indispensable container for photovoltaic, semiconductor and other industries

Quartz crucible: an indispensable container for photovoltaic, semiconductor and other industries 1. Understanding the Quartz Crucible Quartz crucibles have the advantages of high purity, strong temperature resistance, large size, high precision, and good heat preservation. Especially in the process of silicon crystal growth, the quartz crucible has become an irreplaceable key component! Quartz crucibles can be used below 1450°C and are divided into two types: transparent and opaque. The earliest quartz crucibles were all transparent. This transparent structure easily led to uneven [...]

The super “power” of 5G – gallium nitride(GaN)

The super “power” of 5G – gallium nitride(GaN) The world is excited about 5G technology. 5G will deliver lightning-fast speeds 20 times faster than 4G LTE and open up a host of innovative applications and opportunities beyond our imaginations.But it also requires overhauling existing network infrastructure—especially RF power applications. GaN technology is the key to driving this new type of infrastructure. Gallium nitride (GaN) is a relatively new semiconductor for commercial applications. Its power efficiency, power density, and ability to handle [...]

Porous Metal Industry Overview

Porous Metal Industry Overview Porous metal refers to the metal body is made of tiny spherical bodies (commonly known as powder) sintered at high temperature, and the inside of the metal is covered with extremely tiny pores in all directions, hence the name porous metal, also called breathable metal. A large number of directional or random holes are dispersed inside the metal, and the diameter of these holes is between 2um and 3mm. Due to the different design requirements for [...]

How NdFeB magnets work, function and application range

How NdFeB magnets work, function and application range NdFeB magnets were invented in the early 1980s, and as of 2009, are the strongest permanent magnets available. Their strength, small size, and low cost have enabled many advancements in personal audio, electric motors, and other fields. NdFeB magnets are made from an alloy called NIB – neodymium, iron and boron. They belong to rare earth magnets, that is, metal magnets made of rare earth elements. The arrangement of electrons in rare earth [...]

Reasons for the popularity of SiC compared to traditional silicon wafers

Reasons for the popularity of SiC compared to traditional silicon wafers Silicon carbide (SiC) is an unfamiliar term to most people, but it has exploded in popularity in recent years and has become a key third type of semiconductor material in 5G and electric vehicles in the future. With the “Tesla effect” driven by the SiC car boom is just the beginning, with the further increase in the global market penetration of new energy vehicles, the future of the SiC [...]

Refractory insulation bricks multi-wire cutting

Refractory insulation bricks multi-wire cutting Refractory insulation bricks are refractory raw materials fired from refractory raw materials. They can be used as high-temperature building materials and structural materials for building kilns and various thermal processing equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures. When using refractory bricks, they are generally cut into bricks of different sizes. In terms of cutting, it is necessary to choose a suitable cutting method. Some manufacturers use a band [...]

Introduction of hardness, classification and cutting of alumina industrial ceramics

Introduction of hardness, classification and cutting of alumina industrial ceramics 1.Introduction to the hardness of alumina industrial ceramic The hardness of alumina industrial ceramic is extremely high. Whether it is polycrystalline alumina industrial ceramics or single crystal alumina industrial ceramics, it has a high hardness of stainless steel. Due to the hardness of ceramic brackets, it can reach more than nine times that of stainless steel and enamel. So when our teeth are in contact with ceramic brackets, the enamel will be [...]

The “high fever” of silicon material prices will not recede, and the photovoltaic industry is “loaded forward”

The “high fever” of silicon material prices will not recede, and the photovoltaic industry is “loaded forward” “The price of silicon material has reached 310,000 yuan/ton, and it will only be 80,000 yuan/ton at the beginning of 2021, and there is no possibility of price decline in a short period of time.” On July 26, a person in the photovoltaic industry told a reporter from Shanghai Securities News. The price of silicon material continued to rise, which eventually led to the rise [...]
