How to Replace MoSi2 Heating Elements in Zirkonzahn Zirkonofen 600
Introduction
This step-by-step guide will show you how to safely replace MoSi2 heating elements in your Zirkonzahn Zirkonofen 600 dental sintering furnace. At Walla BC, we provide high-quality replacement elements and want to ensure you can install them correctly and safely.
⚠️ Important Safety Warning
CAUTION: All spare parts must be handled carefully since they are fragile.
MoSi2 heating elements are ceramic-based and extremely brittle. Handle them like fine glassware. Never bend, twist, or drop them.

Before you begin:
- Disconnect all power to the furnace
-
Allow furnace to cool completely (minimum 6-8 hours)
Tools You'll Need
- 4mm Allen key (hex wrench)
- Phillips head screwdriver
- Safety gloves
- Digital calipers (for verification)
Step-by-Step Replacement Process
Removing the Old MoSi2 Heating Element


Installing the New MoSi2 Heating Element



After Installation - Testing
Before Powering On:
✓ All screws are installed and tightened ✓ No tools left inside the furnace
✓ Cover plate is properly seated ✓ Element is properly positioned
Test Cycle:
- Restore power to the furnace
- Monitor for any unusual sounds, smells, or arcing
- If all is normal, proceed with a full sintering cycle (empty)
Common Mistakes to Avoid
❌ Over-tightening the ceramic terminal block - This is the #1 mistake. The ceramic will crack.
❌ Bending or twisting the element - MoSi2 is extremely brittle and will break.
❌ Wrong terminal block position - Must be exactly 3.6-3.7 cm from element end.
❌ Forcing the element into insulation - If it doesn't slide in smoothly, check alignment.
❌ Skipping the test cycle - Always test at low temperature first.
