Description

Large diameter tube furnace:Large tube diameter, long thermostatic zone, precise temperature, suitable for multi-sample sintering or pilot experiments.
This model is widely used in the field of semiconductor, nanomaterial, carbon fiber, graphene, etc. It is a cost-effective equipment.

Features

The large-diameter tube furnace is composed of a heating system, a temperature control system, a working tube, a sealing kit and an automatic opening structure of the furnace cover. It can work under vacuum or atmosphere protection to meet various CVD process requirements. Multiple temperature zones can be set. Realize high uniformity temperature field conditions, and can also be applied to temperature field gradient experiments of materials. This product is widely used in pilot sintering and products in graphene materials, lithium battery positive and negative electrode materials, semiconductor materials, new energy and new material industries batch heat treatment
