Sapphire, do you know it? In regularly, it always shines, has blue color, edges and corners covered on its surface. But what we referred here is not the sapphire in the jewelry. It is ….in the following:

Yesterday, we received an inquiry of sapphire growth furnace parts which were made of pure molybdenum, tungsten and steel. It had so many parts and I got 73 drawings from my customer, it just made me crazy. Today, I send out the quotation table and drawings which were drew by me and my chinatungsten colleagues with CAD. Ahha~ CAD, just let me get the chance to practice this skill.

Mentioned sapphire growth furnace, may be you have no idea about it. Ok, let me have an instruction about it.

Sapphire

Sapphire growth furnace is a production proven system that produces high quality boules of exceptional crystal for the industry of LED. This furnace has been a increasing demand system for the high volume sapphire producers. One of the main reasons are the fast increasing requirement of LED. In the system of sapphire growth furnace, tungsten and molybdenum products are the most choice for the sapphire growth, or crystal growth.

Products made of tungsten and molybdenum is the main material for sapphire growth furnace. The products of tungsten and molybdenum are made of the material of tungsten and molybdenum whose purity are over 99.95%. They include tungsten crucible, tungsten plate, tungsten sheet, tungsten wire, tungsten electrode screen and molybdenum crucible, molybdenum plate, molybdenum sheet, molybdenum heater, molybdenum holder and molybdenum electrode screen etc. Besides the pure tungsten and molybdenum products, tungsten rhenium wire is also a main product for the application of sapphire growth furnace.

Tungsten crucible and molybdenum crucible are main products for sapphire growth. Tungsten and molybdenum crucible are used as heating element in the process of sapphire crystal growth. For the property of high melting point of tungsten crucible and molybdenum crucible, tungsten and molybdenum are better choice for the sapphire growth for they will not melt with the crystal and can assure the purity and high quality of the crystal, which can be produced high quality LED material.
