Silicon carbide vacuum sintering furnace is a high temperature sintering equipment, mainly used for the preparation of high performance ceramic materials and composite materials. The principle is to use the chemical reaction and physical process at high temperature to sinter the powder material into a dense block material.

The main components of silicon carbide vacuum sintering furnace include furnace body, heating element, vacuum system, gas control system and temperature control system.

Among them, the furnace body is a closed container made of high-temperature refractory material, which can withstand high temperature and vacuum environment.

The heating element usually adopts resistance heater, which can provide high temperature heating energy.

During the sintering process, the vacuum system can pump out the gas inside the furnace body to form a high vacuum environment to avoid adverse effects such as oxidation and pollution.

The gas control system can control the atmosphere inside the furnace to meet the sintering requirements of different materials.

The temperature control system can monitor and control the temperature in the furnace in real time to ensure the stability and controllability of the sintering process.

In a silicon carbide vacuum sintering furnace, the powder material is firstly placed in the furnace body, and then gradually heated up by the high temperature energy provided by the heating element. When the temperature is recognised to a certain level, the powdered material starts to undergo chemical reactions and physical processes to form a dense lump of material. During the sintering process, a vacuum system extracts the gases from the furnace to create a high vacuum environment to avoid undesirable effects such as oxidation and contamination. The gas control system can control the atmosphere inside the furnace to meet the sintering requirements of different materials. The temperature control system can monitor and control the temperature inside the furnace in real time to ensure the stability and controllability of the sintering process.

The stability and controllability of the sintering process can be achieved through various technical means such as vacuum system, gas control system and temperature control system, so as to meet the sintering requirements of different materials.
