Calcined Olive Sand

Calcined olivine sand, also known as calcined forsterite or light-calcined forsterite, is made from re-burned forsterite, with magnesium oxide (MgO) as its main component (the core component of forsterite is transformed after calcination). Its chemical formula is MgO·Fe₂O₃·SiO₂. After high-temperature calcination, impurities are further removed, endowing it with higher purity, stronger high-temperature resistance and erosion resistance, making it suitable for industrial scenarios with more stringent requirements on raw material performance.

China Mineral (Yingkou) Magnesia Co., Ltd.(CMMC) deeply explores the olivine resources in Dashiqiao and builds a differentiated product matrix around olive sand and calcined olive sand. Based on high fire resistance, it meets the needs of multiple industries such as foundry, refractories, and construction, and constructs a full-chain service system covering "raw materials - processes - applications".

Product Details

Core Advantages

 

  • Breakthroughs in calcination technology: Adopting precise temperature-controlled calcination technology to realize recrystallization and impurity separation of forsterite, ensuring high purity of products (MgO 46-50%) and low loss (LOI ≤ 1% max);
  • Multi-dimensional performance upgrading: Compared with natural olivine sand, after calcination, its high-temperature resistance, erosion resistance and vibration resistance are significantly improved, providing a "performance multiplier" for high-end refractories and special metallurgy;
  • Customized services: Supporting customization of 2-5mm particles and fine powders (ground on demand) to meet the deep processing needs of refractory mortar, high-end casting coatings, etc.

Application Scenarios

 

  • Metallurgical industry: As a raw material for refractories in steelmaking, it purifies molten steel, improves steel quality, reduces the risk of impurity introduction during steelmaking, and helps iron and steel enterprises upgrade their products;
  • High-end refractory manufacturing: Processed into high-quality magnesia, it is used in high-end refractory products such as magnesia bricks and magnesia-carbon bricks, enhancing the erosion resistance and structural stability of the products in high-temperature environments above 1600°C;
  • Glass industry: Applied to key parts such as glass kiln pool walls and channels, it reduces the frequency of kiln maintenance and extends the service life of kilns to 8-10 years by virtue of its strong resistance to glass melt erosion;
  • Rubber and chemical industry: As a functional filler, it improves the strength and wear resistance of rubber products (with wear life increased by more than 30%), or is used in the lining of chemical reaction kettles to withstand high-temperature and highly corrosive environments.

 

Service Support

 

CMMC creates differentiated value for customers through its three-dimensional "resources + technology + application" services:

  • Technical collaboration: For industries such as foundry, refractories, and glass, dispatch material engineers to be stationed on-site, providing full-process support covering "raw material selection - formula optimization - process debugging" to solve practical production pain points;
  • Customized production: According to customers' end product needs (such as high-end steel castings, special refractory bricks), customize parameters like particle size, composition, and purity of olivine sand/calcined olivine sand to achieve precise matching between "raw materials and products";
  • Logistics and reserve: Relying on the logistics hub of Dashiqiao production area, realize agile delivery in "small batches and multiple batches", and cooperate with customers to establish safety stock to ensure the continuous operation of production lines;
  • Exclusive for new customers: Launch a package of "sample testing + process diagnosis", providing free samples of olivine sand/calcined olivine sand and application feasibility analysis to lower the cooperation threshold. For details, please contact the foreign trade team.
