I-Shaped MoSi₂ Heating Element for High-Temperature Furnaces

ZYLAB I-Shaped MoSi₂ Heating Element

Introduction

The I-Shaped MoSi₂ Heating Element from ZYLAB is a high-performance, single-rod heating solution designed for use in electric furnaces operating up to 1800°C. Made from molybdenum disilicide (MoSi₂), this element provides excellent oxidation resistance and stable electrical properties, making it ideal for both laboratory and industrial heat treatment applications.

With its simple, straight design, the I-shaped element is particularly suitable for vertical or custom furnace layouts requiring compact, direct heating.

  Ideal for integration into custom furnace designs requiring high-efficiency and high-durability elements.

Features & Benefits

• Straight Single-Rod Design
  Ideal for limited-space installations or vertically mounted furnace chambers.

• High Temperature Resistance
  Maximum operating temperature up to 1800°C in oxidizing atmospheres.

• Excellent Oxidation Performance
  Forms a protective SiO₂ layer in air, significantly extending service life.

• Stable Electrical Conductivity
  Consistent performance across a wide temperature range with low resistance drift.

• Customizable Dimensions
  Tailored length, diameter, and resistance available to match your furnace specifications.

• Fast Heating Response
  Low thermal mass ensures quick ramp-up and temperature stability.

Physical & Chemical Properties

Oxidation Resistance:
At high temperatures, a dense quartz (SiO₂) layer forms on the surface, preventing further oxidation. If the temperature exceeds 1700°C, the SiO₂ layer melts (m.p. ≈1710°C), but reforms once cooled, maintaining protection.

Avoid prolonged use between 400–700°C, as severe low-temperature oxidation may cause element degradation.
