Product Description:
Product Brief Introduction:
Calcined flint clay, also known as chamotte or calcined kaolin,has heat resistance and sinterability, mainly used for refractory materials and investment casting materials.It is formed by high temperature calcination of flint clay ore.The common colors of flint clay after high temperature calcination are: pure white, light gray, light Yellow brown.
The composition of calcined flint clay is stable, the teture is uniform, the structure is compact, the glaze is bright and magnetic. The main chemical components are AL2O3 and SiO2, accompanied by a small amount of Fe2O3 and trace amounts of Na2O, K2O and other impurities. The high-quality coke gemstone has a refractoriness of over 1750 °C. The main mineral phase is mullite, which accounts for 35 to 55%, followed by glass phase and cristobalite.
Characteristics：
1. High refractoriness.
2. Physicochemical stability.
3. Bulk density high .
4. Low porosity.
5. Low water absorption.
6. Fully calcined
7. Low impurity content.
8. Pure white.

Flint clay customization requirements:
I. Product specifications
Chemical composition: the content of AL₂O₃ should be between 45% and 47%, the content of SiO₂ should be controlled in [specific numerical range], the content of Fe₂O₃ should not exceed [specific numerical value], and the content of other impurities (such as Na₂O and KO) should meet the industry quality standards. For details, please refer to the relevant standard documents provided by our company.
Particle size distribution: This customized flint clay product should contain various particle size specifications for different application scenarios. The details are as follows:
Blocks: 0-1mm, 1-3mm, 3-5mm, 5-8mm, 8-15mm and other specifications. The proportion of each specification should be accurately allocated according to the ratio table provided by our company to ensure that the products can meet the specific filling and structural requirements in subsequent use.
Powder: -200 mesh, -270 mesh, -325 mesh, etc. The fineness uniformity of powder should reach [specific percentage] or more to ensure the consistency of performance in fine processing or mixed use.
II. Product performance
Fire resistance: the product must have high fire resistance, and the fire resistance temperature should reach above 1780℃ to meet the demand of our company in high temperature environment and ensure the stability of product structure under extreme conditions.
Physico-chemical stability: under the normal use environment, the product should have good thermal shock resistance, corrosion resistance and chemical corrosion resistance, which can keep its physical and chemical properties unchanged for a long time and reduce the product performance attenuation caused by environmental factors.
Other characteristics: the product should have low porosity and low water absorption (the water absorption rate should be controlled below [specific value]), and it is a fully calcined product to ensure its high strength and durability during use.
III. Quality Control
Your company needs to carry out strict quality inspection on customized products according to the quality inspection standards provided by our company (see the attachment for details), including but not limited to particle size analysis, chemical composition analysis, physical performance test, mineral composition test and PH value test, so as to ensure that each batch of products meets the customization requirements.
Before the products leave the factory, a complete quality inspection report should be provided, which should record the results of various inspection indexes in detail, and attach the inspection methods and basis for our acceptance and filing.
If quality problems are found during the use of the products, your company should deal with them in time according to the contract and bear the corresponding responsibilities and losses.
IV. Packaging and Transportation
Packaging: The product should be packaged in 1000kg big bags or 25kg small bags, and the firmness and tightness of the packaging should be ensured to prevent the product from being affected by moisture, damage or pollution during transportation. The product name, specification, weight, production date, batch number and contact information of your company should be clearly marked on the package.
Transportation: The transportation mode is arranged by your company, but it is necessary to ensure the safety during transportation and avoid the damage of products due to bumps and collisions. Appropriate protective measures should be taken during transportation, such as moistureproof and rainproof, to ensure that the quality of products is intact when they arrive at our company.
