1900 Molybdenum Disilicide (Mosi2) Heating Element

Why does the color of zirconia turn yellow after sintering?

1900 Molybdenum Disilicide (Mosi2) Heating Element

The primary reason of zirconia yellowing and how did we avoid it?

The purity of the heating element is low and heater’s protective film falls off on zirconia. Zirconia is polluted.Sunshine high quality dedicated Mois2 heating elment for zirconia sintering.We can help you get white and pure zirconia.Sunshine high quality dedicated Mois2 heating elment for zirconia sintering.We can help you get white and pure zirconia.

Another reason of zirconia yellowing and our advantage.

Sunshine Mois2 heating element’s protective layer features a densely compacted yet ultrathin structure that effectively resists detachment during operation.Other manufacturer’s protective layer exhibits a porous and relatively thick configuration that they are easily to fall off.

Product use and maintenance

1. Molybdenum DiSilicide (MoSi2) is a special material that has the best properties of both ceramic and metallic materials. However they are hard, crisp and low impact strength at room temperature. Therefore to be careful to avoid damage during transport and installation.

2. When MoSi2 elements continuously operate in an oxidation atmosphere, the surface temperature of 1700 type should not exceed 1700 ℃(3092℉), 1800-type should not over 1800 ℃(3272℉) and for intermittent use, 1700 type-element should not over 1650 ℃(3002℉), 1800 type element can not exceed 1750 ℃(3182℉), 1900 type-element cannot exceed 1850 ℃(3362℉).

Furnace dryness

New or old furnace which don’t be used for a long time need to be dry before it is used, the drying temperature is 100 ℃(212℉) to 200 ℃(392℉).

However, if the element is used for a long time under the low temperature, it will cause the low-temperature oxidation.

For little furnace, the drying time is short, the influence of several drying hours is little, but for large furnace, which need to be dried for a long time, you had better open the furnace door to ventilate well. You can open the furnace door ajar with the temperature increment and completely close until the temperature reach 1000 ℃(1832℉) above.

If the furnace dry out has been completed or does not need drying, it has to rise its temperature. In order to avoid the oversized electric current impact and cause the electrical equipment overload;

Please go up the furnace temperature according to the following table.
