Graphite boats — also called graphite molds or sintering carriers — hold raw materials and parts in position for high-temperature sintering. Machined from artificial graphite, they are widely used in powder-metallurgy and cemented-carbide sintering.
A graphite boat is a graphite mold. The mold itself acts as a carrier: the raw materials and parts that need to be positioned or shaped are placed together inside the graphite mold and sintered into form at high temperature. Because graphite molds are machined from artificial graphite, they are sometimes called graphite boats or graphite ships.
Graphite molds offer high-temperature resistance, do not contaminate the medium and have a low coefficient of thermal expansion. They also withstand rapid heating and cooling, which is why they are widely used in powder-metallurgy sintering processes such as cemented carbide (hard alloy).
