How to detect zirconia raw materials

Release time：2024-09-18click：0

Zirconium oxide ceramics This special material quality has been accepted by more and more industries. As a zirconia product finishing company, ceramics should control the raw materials good. Since the zirconia ultrafine powder material is a very complex substance, correctly evaluating and characterizing the performance of zirconia ultrafine powder is an important manifestation of responsibility for customers.

Our company (Mingrui Ceramics) uses the following methods and instruments to detect (check and test) the various properties of the product:

1. Appearance quality inspection Carry out visual inspection, using ordinary visible light, within a distance of 1m.

2. Determination of purity The method is carried out according to GB2590.1--81 "Determination of the content of zirconium oxide and hafnium oxide in zirconium oxide and hafnium oxide", or the 100%-impurity method is used.

3. Press GB10724- -89, use atomic absorption spectrophotometer to measure Fe2O3 and Na2Containing proportion of O and MgO.

4. Press GB2590. 3--81, use a 721 spectrophotometer to measure the specific gravity of SiO2.

5. Press GB2590. 6--81, use a 721 spectrophotometer to determine the specific gravity of TiO2.

6. Press GB2890. 4--81, use 721 spectrophotometer to measure the specific gravity of Ai2O3.

7. Use JY- -38ⅡAES (atomic emission spectrometer) determines the Y2O3 content.

8.Cl-contains The specific gravity is determined according to GB9729--88 "Chemical Reagents-General Method for Determination of Chloride".

9.H2O contains specific gravity The determination is carried out according to GB6284--86 "General method for determination of moisture content in chemical products-gravimetric method" (110℃1hr).

10. Use the weight method Determine the loss on ignition of the product.

11. Use Mastersizer2000 laser Particle size analyzer (0.02~2000um) measures the average particle size of the product.

12. Use liquid nitrogen The adsorption multi-point BET method was used to determine the specific surface area of the powder.

13. Use scanning electron microscope Observe the particle morphology, and use a transmission electron microscope to determine the particle size and distribution.
