What is Graphite boat?
The graphite boat is a kind of graphite mold, using as a carrier, which can put the raw materials and parts that we need to position or shape together in the graphite mold for high-temperature sintering. The graphite mold is made of artificial graphite blocks by mechanical processing. Graphite boats are also called graphite boxes, graphite saggers, and graphite molds.
1. Good conductivity (second only to copper and aluminum)
Good thermal conductivity (approximately 1/3 of copper, 1/2 of aluminum, and 2 times of steel at room temperature)
2. The coefficient of thermal expansion is particularly low
The strength increases at high temperatures and approximately doubles at 2500°C. (Compressive strength ≈ 2 times the compressive strength).
Instructions for use of graphite boat / graphite box
Our company produces and processes graphite boxes according to customer drawings, and uses wooden box packaging to ensure the safety of the goods. The timeliness and transportation safety of the cooperative logistics company are guaranteed, so that customers have no worries about after-sales.
Our company produces all kinds of fine-grained high-purity artificial graphite blocks suitable for processing graphite boxes throughout the year, and specializes in processing various specifications of graphite boxes and graphite trays. Using fine-grained high-density graphite as the raw material, the processed graphite box has the characteristics of high temperature resistance, oxidation resistance, high body density, etc., which can be used in a variety of harsh high temperature environments. It is the first product for customers in the high-end graphite industry at home and abroad.
