Preparation equipment: 1800 ℃ small vacuum tube furnace

Main parameters

·Long term working temperature: 800-175

·Recommended heating rate: below 1400: ≤ 10 ℃/min; 1400 ℃ to 1600 ℃: ≤ 5 ℃/min; After 1600 ℃: ≤ 2 ℃/min

·Heating zone length: 295mm

·Maximum power: 5.2KW

·Voltage: single-phase AC220V 50Hz

Furnace structure

·The furnace insulation material adopts high-purity alumina fiber, and is embedded with lining zirconia plate (thickness 10mm, fire resistance 2300 ℃) inside

炉管

·(Standard) OD: 60mm x 1000mm L

·In order to ensure the uniformity of the temperature field and the sealing of the flange, aluminum oxide tubes need to be inserted at both ends of the furnace tube to prevent heat loss before the instrument is used for heating up

vacuum sealing

·Comes standard with a pair of stainless steel vacuum flanges and high-temperature silicone sealing rings

·Optional: To achieve higher vacuum levels faster, it is recommended to use KF25 stainless steel flanges, stainless steel bellows, and digital vacuum display gauges

flange interface

·In order to achieve a better vacuum state, the KF25 adapter can be selected to connect the outlet flange to the corrugated pipe

·Multiple types of connectors are available, please inquire with our sales department for details

真空度

·The vacuum degree of the double rotary vane mechanical pump can reach 10-3 torr

·If you want to achieve a higher vacuum degree (<10-5 torr or better), you can choose domestic or imported high vacuum units

optional

·The anti-corrosion digital vacuum display meter imported by our company has a measurement range of 3.8x105 to 1125 Torr. No coefficient conversion is required due to different types of gases being measured

Temperature Control System

·Includes a YD858P temperature controller

·PID automatic temperature control system

·Intelligent 50 segment programmable control

·Temperature control accuracy: ± 1 ℃

·Default DB9 PC communication connection port

·Optional computer temperature control software (for YD858P series controllers) can be used to control the heating curve and export data.

heating element

·Kathal 1900 grade silicon molybdenum rod, manufactured in Sweden

warranty period

One year warranty, lifetime technical support.

Special reminder: Consumables such as heating elements, quartz tubes, sample crucibles, corundum tubes, thermocouples, etc. are not included.

2. Damage caused by the use of corrosive and acidic gases is not covered by the warranty.

Application precautions

·The pressure inside the furnace tube cannot exceed 0.02MPa

·Due to the high internal pressure of the gas cylinder, a pressure reducing valve must be installed on the cylinder when introducing gas into the furnace tube. It is recommended to purchase a pressure reducing valve from our company, which has a range of 0.01MPa-0.1MPa and can be used more accurately and safely

·For the experiment of sample heating, it is not recommended to close the exhaust valve and inlet valve at the flange end of the furnace tube. If it is necessary to close the gas valve to heat the sample, it is necessary to constantly pay attention to the reading on the pressure gauge. If the pressure reading is greater than 0.02 MPa, the vent valve must be opened immediately to prevent accidents (such as furnace tube rupture, flange flying out, etc.)

·The gas flow rate should be limited to<200 SCCM (or 200ml/min)
