Abstract. The potential of a microwave heating technique for the sintering of 3Y-TZP ceramics is demonstrated. High density samples were obtained by short duration firing in a domestic microwave oven. The ultrafine and monomodal size distribution of grains resulting from the process has important implications in terms of mechanical properties.
sintering, and from 7.31% to 9.17% for microwave sintering. The microwave-sintered specimen demonstrated a smoother surface and a more uniform grain structure compared to the conventionally-sintered specimen. CONCLUSION. With reduced processing time, microwave-sintered pre-colored dental monolithic zirconia
Its heating rate is 10-100 times faster than that of the traditional furnace. As a kind of lifting microwave fast heating high temperature furnace, microwave zirconia teeth sintering furnace is particularly suitable for the sintering of zirconia teeth, which can save energy greatly and improve productivity.

It features a molybdenum disilicide heater that provides clean, reliable, and consistent results. Quick Firing Program
The sintering assembly was constructed by modifying a domestic 1.5 kW, 2.45 GHz microwave oven (BPL India). Green samples were placed inside a casket made of zirconia fibre board. This was covered with alumina wool for heat containment.
Features of zirconia sintering furnace : (1).Upgrading control system with touch screen for easy operating. (2).Cylinder heating chamber deisgn with six pieces heating element. (3).Auto lifting and downing tray for convenient products loading and picking. (4).High purity heating elements and chamber materials to keep zirconia translucent.
High-Temperature Furnaces up to 1650 °C for Sintering Translucent Zirconia. The special heating elements made of molybdenum disilicide promise the best possible protection against chemical interaction between the charge and the furnace components. The bridges and crowns are loaded in ceramic saggars.
Applying microwave technology to sintering dental zirconia. In a standard conventional furnace, heat is applied to the external surface of the restoration and reaches the core by thermal conduction, producing high temperature gradients and stresses within the material. It is not a uniform heating process.
