1700°C CVD Tube Furnace

1700°C Tube Furnace Chemical Vapor Deposition (CVD) refers to the method of chemical gas or steam reacting on the surface of the substrate to synthesize coatings or
nanomaterials. It is the most widely used technology in the semiconductor industry to deposit a variety of materials, including a wide range of insulating materials,
most metallic materials and metal alloy materials.

Features

Furnace shell

1. The shell is made of metal Q235 low-carbon steel, and the surface is electrostatically resistant and resistant to corrosion.
2. The solid double-layer metal frame is combined with the heat-insulating fan structure, and the furnace surface temperature is low
3. Horizontal use mode, upper opening structure, easy to operate

Refractory material

Multi-layer insulation design, composed of lightweight alumina ceramic fiber and high-quality insulation board backing, does not contain asbestos components, low heat loss and low energy consumption

Heating system

1. High-quality MoSi2 spiral resistance wire heating element is safely and firmly embedded on the surface of the furnace, and is heated by free heat radiation in the furnace cavity, which is energy-saving and efficient, and has a long service life
2. Ring heating by resistance wire to achieve good uniformity in the furnace

Temperature Control Panel

1. PID and SSR control mode, precise temperature control
2. Internationally standardized B-type nickel-chromium-silicon thermocouple with a temperature measurement range of 0-1600℃ and a long service life
3. The furnace door is equipped with a door-opening power-off safety protection switch

Program Controller

1. Advanced controllers that meet complex process requirements
2. Simple and direct operation, flexible programming
3. Programmable 30 program segments for a single curve
4. Over temperature and fault alarm, automatic safety protection

Vacuum Atmosphere Function

1. With 304 stainless steel sealing flange to obtain vacuum or atmosphere in the furnace tube
2. High-quality quartz glass working tube, and metal or corundum working tube can also be selected to adapt to different working conditions
3. The high-performance bipolar rotary vane vacuum pump can obtain a vacuum degree of 5pa, and the digital vacuum gauge can display the vacuum degree
4. With air circuit control unit, the control unit can choose 1-3 way MFC automatic control system
