Zirconia Zirconium Crucibles
For the formation of semiconductor crystals, zirconia zirconium crucibles are the preferred option.
With a purity of 99.9, a density of 6.00, and a maximum operating temperature of 2200°C, Zirconia Zirconium Crucibles are mainly used in the melting of precious metals and have good resistance to heat.The primary use is for melting priceless and rare metals. Due to their high-temperature stability, zirconia crucibles are perfect for testing high-temperature refractory materials. One of the best refractory materials found in nature, zirconium dioxide has a melting point that is greater than zirconium, at 2700°C. Even when heated to above 1900°C, it does not interact with molten aluminum, iron, nickel, platinum, silicates, or acidic slag due to its poor thermal conductivity, excellent electrical conductivity, and resistance to corrosion. As a result, it can be utilized to create smelting refractory goods. Crucibles, refractory tubes, heat-resistant glass, and heat-resistant enamels can all be produced using it to melt priceless metals.
Enamels and glass are more resistant to acid and alkali corrosion when Zirconia Zirconium Crucibles are used. Temperature variations have virtually little effect on the volume of zirconium dioxide-lined high-temperature furnaces during heating. The furnace body does not crack as a result of thermal expansion and contraction, thus increasing the furnace's lifespan.
The refractory substance is zirconium dioxide, while the stabilizer is 5% calcium oxide.
Its heat resistance is 500 degrees higher than that of alumina, and its adiabatic capacity is three times bigger than before it was added. In order to make the ceramic whiter, brighter, stronger, and more heat resistant, white zirconium dioxide is added to it. This ceramic is then utilized to create high-temperature insulating vases with a high insulation capacity and a low expansion coefficient.
In laboratories, chemicals are heated to high temperatures using a device called a crucible that has a cup-like shape. With a high degree of applicability and to guarantee the purity of the substances to be melted, the crucible is available in a wide range of models and specifications and can be chosen at will for its application. This is true regardless of the scale of production, the size of the batch, or the variety of substances to be melted.
1. The crucible should be baked gently to 500°C before use, then stored in a dry location after use to prevent rainfall entry.
2. Fill the crucible with material in accordance with its capacity, but avoid packing it too tightly to prevent the crucible from cracking due to thermal expansion of the metal.
3. Use a spoon to scoop out the molten metal, and use calipers as little as possible. If you must use a tool like a caliper, be sure that it fits the shape of the crucible to prevent using excessive local force that could limit the tool's lifespan.
4. The lifespan of the crucible depends on its use; it is best to avoid spraying it directly with intense oxidation flames to prolong the lifespan of the crucible's raw material oxidation.
