RTP-CZ-2000 is designed for growing diamond fiber and crystal from liquid metal. It heats rapidly a graphite crucible via resistance up to 2000 °C in a high vacuum SS chamber, and pulls a crystal at a variable speed. This compact CZ grower can also grow various metallic crystal samples up to a 2000 °C melting point
