Lifting Method And Lifting Furnace:
　　The lifting method, also known as the Czochralski method or simply the CZ method, was invented by J.Czochralski in 1917 for the purpose of lifting and growing high-quality single crystals from a melt. The Czochralski method is a commonly used technique for single crystal growth, capable of producing a variety of crystals including lithium niobate, lithium tantalate, yttrium aluminum garnet doped with magnesium fluoride, sapphire, spinel, yttrium vanadate, and more. The furnace used for growing crystals by the Czochralski method, also known as the lifting furnace, typically includes components such as a heating device, a driving device, an atmosphere control device, and a control device, among others.

Guided Mode Method:
　　　Guided mode method was proposed by Soviet scholar Stepanov around 1960, also known as Stepanov method or EFG method. This method has evolved over time and has become an important method for crystal growth. The crystal growth method has the advantages of fast crystal growth, low cost, simple crystal processing and uniform composition. Guided mode method is applied in many fields such as single crystal fiber, sapphire fairing, sapphire pipe, bar and so on.

Descent Method:

The descent method was proposed by Bridgmen in 1925, so it is also called the Bridgmen method. The principle of this method is to load the crystal raw material into the crucible, and realize the crystal growth through the relative movement of the furnace body and the crucible. The descent method is often used to grow low-melting scintillation crystals, such as bismuth germanate crystals, cesium iodide crystals, lead tungstate crystals, etc. The descending furnace generally adopts tubular design and generally has three temperature zones, namely, high temperature zone, gradient zone and low temperature zone.
