The main raw material of graphite crucible is crystalline natural graphite. Because it retains all kinds of physical and chemical properties of natural graphite. It has good thermal conductivity and high temperature resistance, in the process of high-temperature use, the coefficient of thermal expansion is small, and it has a certain strain-resisting function for hot

Graphite has the following special properties because of its special structure: 1. High temperature resistance: Graphite Melting point is 3850±50℃, boiling point is 4,250 ℃, even after the ultra-high temperature arc burning, the loss of weight is very small, the coefficient of thermal expansion is also very small. The graphite strength increased with the increase

Because of the unique properties of carbon-graphite materials, it has a strong vitality when applied in mechanical industry. In particular, running at high temperatures (or ultra-low temperature), mechanical equipment in strong corrosive medium, because of the use of carbon graphite mechanical parts, so that lubrication and corrosion-resistant problems have been satisfactorily resolved, Minchi development speed,

Adsorption of expanded graphite on water pollution control, has a large number of research results, in terms of controlling oil, organic pollution of water body, far more effectively than current conventional activated carbon expanded graphite and economic. Expanded graphite inconvenient transport, application site preparation needs. Expanded graphite preparation of environmental protection, use, recovery, recycling a

In this artical, Raygroup graphite and carbon electrode will talk about the features of molten copper graphite crucible. 1. Density is between 2.2-2.3, the density is the density of the crucible of the world’s largest, high density making the crucible with the best thermal performance. Its thermal conductivity is better than the other brand crucible. 2. the

International Children’s Day is scheduled for June 1 every year. In commemoration of the leditzer massacre on June 10, 1942 and all the children who died in the war all over the world, we oppose the maltreatment and poisoning of children, and safeguard the rights of children. In November 1949, the International Federation of democratic
