L-Shaped MoSi₂ Heating Element for Laboratory High-Temperature Furnaces

ZYLAB L-Shaped MoSi₂ Heating Element

Introduction

The L-Shaped MoSi₂ Heating Element by ZYLAB is specially designed for high-temperature laboratory and research furnaces that demand accuracy, efficiency, and durability. Made from high-purity molybdenum disilicide (MoSi₂), this element supports temperatures up to 1800°C, delivering stable performance in controlled experimental conditions.

Ideal for horizontal or inclined heating zones, L-shaped elements are widely used in material testing, ceramic sintering, and small-batch thermal experiments where space efficiency and temperature uniformity are critical.

Engineered with stability and longevity in mind, ZYLAB MoSi₂ elements exhibit:

• Stable electrical resistance even after long-term use

• Compatibility between old and new elements in series

• Fast thermal cycling with no performance degradation

• Self-healing SiO₂ protective layer in oxidizing atmospheres

• Custom dimensions for optimized fit and efficiency

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.

MoSi₂ Heating Element Installation Guidelines

Because MoSi₂ elements are brittle at room temperature and ductile at high temperature, careful handling is required:

General Recommendations:

• Install with the L-bend supported to avoid breakage.

• The cone ends must extend into the furnace chamber.

• Do not overtighten the power connectors initially. Tighten again when heated to avoid breakage.

• Use matching ceramic spacers to separate the shanks.

Installation Steps:

1. Remove the wooden block from between the shanks.

2. Insert the element through the ceramic spacer into the mounting hole.

3. Push the element in until it touches the wooden block inside the furnace.

4. Fill any gaps with alumina fiber.

5. Install the ceramic fixture, aligning all screws in one direction.

6. Once all elements are in place, install the power tracks, ensuring they do not contact the fixture to prevent short circuits.

Note: MoSi₂ rods are fragile and should be handled with caution at all times.
