Mosi2 Heater

MoSi2 Heater

Introduction

A MoSi2 Heater, or molybdenum disilicide heating element, is a high-temperature resistance heating device primarily made from the ceramic material molybdenum disilicide (MoSi2). These elements are well-suited for applications that require extremely high temperatures and are commonly used in various industrial and laboratory settings.

Key Features:

High-Temperature Resistance:

Capable of operating at temperatures up to 1800°C (3272°F) in oxidizing atmospheres.

Oxidation Resistance:

When heated in an oxidizing atmosphere, MoSi₂ forms a protective layer of silicon dioxide (SiO₂) on its surface, which prevents further oxidation of the element.

Electrical Conductivity:

MoSi₂ is a good electrical conductor, which is crucial for its function as a heating element.

Durability:

These elements have a long service life due to their high resistance to oxidation and chemical attack.

Thermal Shock Resistance:

Able to withstand rapid temperature changes without cracking.

Common Shapes and Types:

I Shape:

Straight rod elements.

U Shape:

Commonly used, suitable for various industrial and laboratory furnaces.

M Shape:

Designed for specific heating configurations.

L Shape:

Used in specialized applications.

Specifications:

M1700 Type:

Available in diameters such as 3/6, 4/9, 6/12, 9/18, 12/24 mm.

M1800 Type:

Available in the same diameters as M1700 but can withstand higher temperatures.

Applications:

Industrial Furnaces:

Used in heat treatment processes, sintering, melting, and annealing.

Glass and Ceramic Manufacturing:

Employed in the production of glass and ceramics, which require high and consistent temperatures.

Laboratory Equipment:

Utilized in high-temperature laboratory furnaces for research and testing.

Semiconductor Industry:

Used in processes that demand precise temperature control, such as diffusion and oxidation.

Operational Guidelines:

Environment:

Best suited for use in air or inert gas environments. Active gases like hydrogen, chlorine, and sulfur dioxide can damage the element.

Temperature Range:

Avoid prolonged use in the 400-700°C range to prevent oxidation and damage.

Handling:

MoSi₂ elements are brittle at room temperature and should be handled carefully. Avoid rapid heating and cooling to prevent breakage.

Installation:

Typically installed vertically to avoid mechanical stress. Connection wires should allow for thermal expansion.
