Problems solved by technology

The existing method for producing cubic zirconia single crystals is to use an electron tube high-frequency power supply to inductively heat and melt the zirconia raw materials in the water-cooled crucible, and then use the lifting and pulling crystal pulling process to produce cubic zirconia single crystals. The power efficiency of this production method is low. It can only reach about 40%, the working frequency is 300KHZ-1000KHZ, the harmonic components are complex, the power supply and electronic equipment are greatly disturbed, the working stability is poor, the working voltage is too high, reaching 13KV, the components are easily broken down by high voltage, which is not conducive to Safe production, high production cost, low yield, only 40-45%

Embodiment Construction

[0026] The new method for producing cubic zirconia single crystals of the present invention is further illustrated by the following two schemes.

[0027] The method for producing cubic zirconia single crystal in the first embodiment is to use the electric arc furnace power supply as the heating power supply, and the zirconia raw material in the water-cooled crucible is melted by the high-temperature electric arc generated by the electric arc furnace, and then combined with the lifting method to produce cubic zirconia. single crystal method.

[0028] The equipment used in the production method includes: A. AC or DC electric arc furnace heating power supply with a voltage of 10V-200V; B. Water-cooled crucible, which can be made of stainless steel or copper to be round or rectangular; C. Elevator.

[0029] The specific production method is:

[0030] 1. Put the water-cooled crucible on the elevator, and connect the water inlet and outlet pipes;

[0031] 2. Put a 50mm base materi...

Abstract

The invention discloses a new manufacturing method of cubic zirconia monocrystal, which comprises the following steps: adopting electric arc furnace power as heating source; or mating electric arc furnace power and middle-frequency power as heating power; fusing zirconium dioxide in the water-cooled copple; combining with lifting crystal pulling technology to obtain the product.

Description

1. Technical field [0001] The present invention relates to a new method for producing single crystals of cubic zirconia. 2. Background technology [0002] Cubic zirconia single crystal, due to its high refractive index and hardness similar to natural diamonds, is widely used in the gem industry to polish and make jewelry. The existing method for producing cubic zirconia single crystals is to use an electron tube high-frequency power supply to inductively heat and melt the zirconia raw materials in the water-cooled crucible, and then use the lifting and pulling crystal pulling process to produce cubic zirconia single crystals. The power efficiency of this production method is low. It can only reach about 40%, the working frequency is 300KHZ-1000KHZ, the harmonic components are complex, the power supply and electronic equipment are greatly disturbed, the working stability is poor, the working voltage is too high, reaching 13KV, the components are easily broken down by high vol...
