Do you know the difference between carbon felt purification and graphite felt?

Carbon felt is a felt made of carbon fiber, which has a wide absorption spectrum and a large capacity. Graphite felt can be made by high temperature graphitization. Graphite felt is mainly used as thermal insulation material for monocrystalline silicon smelting furnace.Carbon felt purification can be used as adsorption purification material, as insulation material for vacuum furnace and inert gas furnace. In addition, carbon fiber materials have advantages in fields that have strict requirements on strength, stiffness, weight, fatigue characteristics, etc., and in occasions that require high temperature and high chemical stability. The carbon content is about 90%, and the service temperature is about 1000 degrees Celsius.The main use of graphite felt is as insulation material for monocrystalline silicon smelting furnace. It can be used as a filter material for high-purity corrosive chemicals in the chemical industry. Under the condition of non-oxidizing atmosphere, the service tempera

What are the characteristics of graphite bearings?

Graphite bearings are important high-temperature bearings that utilize the self-lubricating, high-temperature resistance, and chemical inertness of graphite materials to operate under high temperature and strong corrosion conditions that ordinary bearings cannot withstand. The main functions of graphite bearings are:

Silicon based anode battery capacity

Although graphite has been used as an anode material for power batteries for decades, its large volume, high weight, and physical and chemical limitations make it difficult to meet the high energy density requirements of electric vehicles. Therefore, silicon-based anode materials are gradually replacing graphite and becoming a new direction in the development of power batt

What are the reasons for the low initial efficiency of lithium carbide graphite negative electrodes

1. Low specific surface area: As you mentioned, the specific surface area of waste graphite is usually low, which leads to a decrease in the contact area between the electrolyte and graphite, affecting ion insertion and extraction during the initial charge and discharge process, thereby reducing the initial Coulombic efficiency. Compaction and coating treatment can increas

Graphite heater

There are weak van der Waals forces between layers in the structure of graphite, and these interactions are disrupted under high temperature conditions, leading to interlayer detachment of graphite.

The main factors affecting the price of graphite molds are as follows

Raw material cost: The price of graphite molds is influenced by the cost of raw materials. The main raw material for graphite molds is graphite material, and its price fluctuations will directly affect the price of graphite molds. The rise or fall in raw material prices can lead to fluctuations in graphite mold prices.
