Carbon and graphite products

（1） Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials, and coal tar pitch as a binder. They are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are conductors that release electrical energy in the form of an arc in an electric arc furnace to heat and melt the furnace material. According to their quality indicators, they can be divided into ordinary power, high power, and ultra-high power. Graphite electrodes include:(1) Ordinary power graphite electrode. Allowing the use of graphite electrodes with a current density below 17A/cm2, mainly used for ordinary power electric furnaces such as steelmaking, silicon smelting, and yellow phosphorus smelting.(2) Anti oxidation coated graphite electrode. A graphite electrode coated with an antioxidant protective layer on the surface forms a protective layer that is both conductive and resistant to high-temperature oxidation, reducing electrode consumption duri

The adaptability of the scale graphite to temperature

Scales graphite is a natural graphite. It is usually a thin piece or scale form. It has a strong adaptability to high temperature and has a strong heat shock resistance. The scale of the scale is added to the production of many products, which enhances the product's ability to work at high temperature. Today, the editor will explain the adaptability of the scale graphite to temperature:Scales graphite has very good high temperature resistance and is one of the high -temperature resistance materials. When higher than 2000 degrees, the general material will appear in a melting state, or it has become a gas, and even some difficult melting metals will lose strength at about 2500 degrees. 3600 degrees, but the scale graphite will not melt at this temperature. The melting point is 3850 degrees.If several high -temperature -resistant materials are placed at 7000 degrees of ultra -high temperature arc for 10 seconds, the losses of scales graphite are extremely small. According to the weight

Factors affecting the quality of silicon carbide grinding powder

Silicon carbide is widely used in industry and plays an important role. Silicon carbide can also be used as an abrasive, so the quality of silicon carbide particles is particularly important. We want to test its quality, so how to test its quality?Before proceeding to the analysis, the first thing we need to understand is that the abrasive is not only composed of particles of one shape, but only depends on the percentage of that shape. When analyzing the shape of abrasive grains, it can also be seen that the edges of the abrasive grain surface have characteristics such as smoothness, sharpness, rounded corners, straight lines, serrations, and cracks.Impurities are often mixed into the grinding powder. One is the components contained in the abrasive grains themselves, which are mainly formed during the smelting of raw materials, such as iron oxide, silicon dioxide, chromium oxide, and sodium oxide. Another kind of impurity is dissociated between particles, mainly iron filings and dust

Will room temperature superconductivity become the next graphene

On July 22nd, a South Korean research team published a paper on the preprint website arXiv, claiming to have synthesized the world's first room temperature and atmospheric pressure superconductor, named LK-99.Superconductivity refers to superconductivity. Under normal temperature and pressure, almost all conductors have resistance, resulting in thermal energy loss during current conduction. Superconductors are materials that can conduct current with zero loss due to the disappearance of resistance, and have complete diamagnetism (internal magnetic induction strength is zero), with advantages such as stability, low loss, and fast transmission.Previously, superconducting materials needed to enter the superconducting state at lower temperatures. The keyword "room temperature superconductivity" mentioned by the Korean team in this paper refers to the phenomenon of superconductivity achieved under room temperature conditions. According to the standards of condensed matter physics
