How do we ensure outstanding quality of our sintered synthetic materials?
Explore our end-to-end production process designed to ensure outstanding quality and consistency of every batch.
01
The qualified starting materials are ground by a ball mill to achieve technologically required fineness, so as to facilitate high temperature solid-solid reaction and sintering to produce qualified sintered material products.
02
The starting powder meeting fineness requirements is pelletized into spheres of the required density and strength, and drying removes free water from the green body to prevent kiln explosion, enhance strength, shorten firing time, and boost production.
03
The purpose of firing at specific high temperature is to induce physical-chemical reactions in the green bodies, promoting the growth and development of crystals and obtaining well sintered qualified balls.
04
According to user needs, the sintered balls are crushed and ground into aggregates of different sizes and fine powders, and the mechanical iron introduced during crushing and grinding is removed.
Applications of our sintered synthetic materials
Our high purity sintered materials are widely used in refractories, polishing, ceramic, glass sectors, etc. Designed for good stability and durability, they ensure reliable performances under tough working conditions.
Key Properties of High Purity Sintered Synthetic Materials
Engineered for high performance and high stability, our high purity sintered materials are characterized by optimized crystal growth, high bulk density and outstanding resistances to slag and erosion，so as to ensure satisfactory performances under severe working conditions.
High Refractoriness
Our high purity sintered materials consistently achieve superior PCE values, as a result of low levels of impurities and additives.
High Thermal Shock Resistance
The capacity to endure rapid temperature changes without cracking is crucial for repeated heating and cooling cycles. Our high purity sintered materials are engineered to maintain structural stability during intensive thermal cycles, ensuring long durability.
High Abrasion Resistance
The capacity to resist wear from mechanical friction or particle impact is essential in applications involving furnace charge movement, like in the case of cement rotary kiln. Thanks to high compactness and favorable microstructure of our sintered synthetic materials, JX MINERALS's products can provide superior durability against surface erosion.
High Chemical Stability
An inertness to chemical reactions with slag , furnace atmosphere or high temperature melt is beneficial to prevent corrosion and hence extend service life. Our high purity synthetic materials are engineered to withstand aggressive chemical environments, ensuring reliable performance and without the risk of contamination from additives.
Optimized Thermal Conductivity
The capacity of a material to conduct or insulate heat depends on its characteristics. High density materials transfer heat easily and insulating materials can reduce heat loss. Our high purity sintered products are engineered with favorable density and other characteristics to ensure superior thermal management in diverse industrial processes.
High Mechanical Strengths
Strengths are required to support structural loads in industrial furnaces and thermal equipments at elevated temperatures. Our high purity sintered synthetic materials have well designed and optimized mechanical properties to ensure structural robustness，stabiliity and load-bearing capacity of the linings.
Low Porosity and High Density
Low porosity can enhances mechanical strengths and resistance to furnace media penetration, while optimized porosity can compromize thermal insulation and other properties. Our advanced production technology ensures low apparent porosity, high compactness and reasonable pore size distribution of our products, providing high strength, robust barrier against penetration and other related properties determining service performance.
Excellent Volume Stability
Minimal volumetric change during heating and cooling cycles is required to ensure dimension accuracy and preventing lining failure. Our high purity synthetic materials，after being fully sintered and optimized in microstructure, exhibit very limited residual shrinkage upon reheating, ensuring good structural stability for high-temperature furnace linings.
