Product Description

This Atmosphere Controlled Muffle Furnace is an economic atmosphere-controlled muffle furnace that is designed for sintering materials under inert gas or vacuum up to 1700oC. The furnace consists of high-quality alumina fiber bricks and MoSi2 heating elements with a heating chamber of 16″x 16″ x 20″.

This controlled atmosphere furnaces feature a chamber with high quality alumina fiber insulation and MoSi2 heating elements. A double walled steel internal housing helps minimize heat loss to exterior surface. Furnace operation is controlled by 24-segment digital controller with built-in RS485 digital communications port and USB adaptor, allowing the user to connect to a PC for remote control and monitoring of the furnace. You can also save or export test results.

Applications

Heat treatment of metals for enhanced hardness and durability.

Sintering of ceramics to achieve desired shapes and properties.

Annealing to relieve internal stresses and improve ductility.

Oxidation and reduction processes for specific material modifications.

Calcination of various substances for purification and chemical changes.
