Microwave sintering furnace for ceramic sintering

Product Description

1.Introduction

1. It’s suitable for technological research in the condition of various atmospheres, such as synthesis,

roasting, heat treatment, sintering, etc and it’s also suitable for technological research in the condition

of high vacuum, such as synthesis, roasting, heat treatment, sintering, etc.

2. It adopts pre-vacuum method to save the time of replacement atmosphere.

3. Rapid heating increases lab efficiency.

4. Large sintering area, good uniformity and small output capacity available.

2.Features of Microwave Heating

Fast heating; Mircowave traveling the speed of light couples heating material and transfers microwave energy to internal energy of material, reducing heat transfer time greatly compared conventional heating, which reduces heat loss and saves energy. Instantaneous adjustment during control process has a good controllability of reaction and sintering out thermal inertia of conventional heating.
Uniform heating; Microwave heats through materials gradientlessly, entirely, synchronously and uniformly, which makes materails organization uniform and inhibits deforming and cracking during heating process.
Grain refinement; With microwave’ s concentrated heating on materials, materials get a rapid temperature rising speed and uniform heating, which reduces holding time, lowers sintering temperature, refines grain and improves material sintering density during sintering process.

Fast heating;

Mircowave traveling the speed of light couples heating

material and transfers microwave energy to internal energy of

material, reducing heat transfer time greatly compared

conventional heating, which reduces heat loss and saves energy.

Instantaneous adjustment during control process has a good

controllability of reaction and sintering out thermal inertia of

conventional heating.

Uniform heating;

Microwave heats through materials gradientlessly, entirely,

synchronously and uniformly, which makes materails organization

uniform and inhibits deforming and cracking during heating

process.

Grain refinement;

With microwave’ s concentrated heating on materials, materials

get a rapid temperature rising speed and uniform heating, which

reduces holding time, lowers sintering temperature, refines grain

and improves material sintering density during sintering process.
