1.Structure of Zircon Sand and Zircon Powder
We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %. We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %. Zircon is a remarkable mineral, if only for its almost ubiquitous presence in the crust of Earth. It occurs in igneous rocks as primary crystallization products, in metamorphic rocks and in sedimentary rocks as detrital grains.
Further, the mineral due to hardness, durability and chemical inertness, zircon persists in sedimentary deposits and is a common constituent of most sands.
2.Main Features of Zircon Sand and Zircon Powder
1 Tiny, round, solid ball shape provides greater surface area for improved performance and dispersion in its application
2 High refractory rating, lower specific gravity rating, and higher service temperature produces greater yield
3 With lower bulk density, it offers better air permeability for better performance as a result of its overall physical characteristics
3.Main usage of Zircon Sand and Zircon Powder
1. The 80-120M zircon sand is used in investment casting, the processing is called dipping.
2. It can enhance the shell`s thickness.
3. It is specialize used in inner layer being mixed with silica sol.

- Q:A chemical problem with refractory materials
- No, in junior high school may be exposed to AlN aluminum nitride, high temperature resistant new ceramic, water will react...
- Q:What is the difference in the nature between the refractory material and thermal?insulation?material
- thermal?insulation?material is a material which has a strong impedance to the heat flow. the nature of the material requires that the material can isolate the delivery of thermal, and the low heat conductivity coefficient and expansion coefficient of the non-metal material.refractory is good in heat resisitance and chamical erosion but not high temperature resistance. Requirements on nature is still in high temperature.
- Q:How many types of fire-resistant material?
- 1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
- Q:Who knows the external wall thermal insulation materials fire rating requirements?
- The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
- Q:What is the magnesium carbon refractory?

- Q:Can quantitative feeder be used in refractory plant? Thank you
- Yes, but the material must be no longer using a simple Q235 material
- Q:What are the requirements on fire resistance period of C-level fireproof glass?
- Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance.
