1. visible Test: The crucible should be visually inspected for signs of cracks, chips, or other signs of damage.
2. angle Test: The crucible should be weighed to insure that it meets the stated weight requirements.
3. thermic Shock Test: The crucible should be subjected to thermic shock testing to ensure that it can withstand fulminant changes in temperature without cracking or deforming.
4. energy Expansion Test: The crucible should be heated to a temperature above the thaw direct of the material and then cooled to control that it can withstand thermal stresses.
5. Impact Test: The crucible should be dropped from a predetermined tallness to verify that it can resist physical science impacts.
6. Corrosion underground Test: The crucible should be exposed to different undefined agents to insure that it is resistant to corrosion.
7. flex Test: The crucible should be bent to control that it is strong enough to withstand physics forces.

Use/Maintenance Methods                                                                                                                                                             

1.Do not use gasoline spraying gun, acetylene gun or alcohol burner for direct heating.
2.Before using the crucible for the first time, put it into an oven with a temperature of about 105 ℃ and bake it for 120 minutes to dry up.
3.The heating/cooling speed shall not be too fast, below 1200 ℃ 5 ℃/min; Above 1200 ℃ 4 ℃/min; It is recommended to use electric control for cooling. A too fast cooling speed in the early stage of furnace cooling at a high temperature after the power is turned off may result in a surface cracking of the crucible.
4.The distance between the crucible and the heating element (silicon carbon tube, silicon molybdenum rod, heating wire, etc.) should be greater than 2CM.
5.The bottom of the crucible shall not have a direct contact with the surface of the furnace. It is recommended to use temperature resistant materials such as corundum sheets to separate the equipment as well as to form air convection.
6.Feed within the capacity of the crucible. Do not squeeze too tightly to prevent the metal from thermal expansion and cracking of the crucible.
7.Taking out the molten metal with a spoon instead of with a caliper is recommended. If a caliper or other tools must be used, the shape of the tool should better be similar to that of the crucible to avoid shortening the life of the container due to an excessive local force upon the crucible.

1.Q: What are the advantages of using a zirconia crucible? 

A: Zirconia crucibles offer a number of advantages compared to other materials. They provide excellent thermal shock resistance and can be used in applications requiring high-temperature operation. They are also corrosion-resistant, making them well-suited for use with corrosive materials. Finally, zirconia crucibles are low-cost, making them ideal for many industrial and laboratory applications.

2.Q:What's the delivery time?

A: 1-7 working days for standard products 20-30 days for customized products.

3. Q:What is the maximum temperature that a zirconia ceramic crucible can withstand? 

A:The maximum temperature that a zirconia ceramic crucible can withstand is around 2,200°C (4,000°F).

4. Q:Are there any safety precautions that need to be taken when using a zirconia ceramic crucible?

A:Yes, it is important to wear protective gear when using a zirconia ceramic crucible. Additionally, it is important to make sure that the crucible is placed on a heat-resistant surface and away from any combustible materials. Lastly, it is important to be mindful of the temperature of the crucible and avoid overheating it as this can cause it to crack or shatter.
