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

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

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

• Remove the wooden block from between the shanks.

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

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

• Fill any gaps with alumina fiber.

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

• 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.
