Bonded by pulp or brine, Magnesia Spinel Bricks are calcinated at high temperature from molding blank bricks which are shaped from certain proportion of ingredients mixed magnesia spinel powder with sintered or fusged magnesia material. During the process, spinel material is very important in produciton. Usually the dosage of spinel is 10 - 20% for the best, and also some propotion of α-Al2O3 fine powder shall be taken as additive.
- Good resistance to erosion;
- Fine resistance to abrasion;
- Excellent thermal shock stability;
- Free of chrome harming environment.
Depending on requirements from customers, we are able to custom accordingly and offer Magnesia Alumina Spinel Bricks and Magnesia Ferros Spinel Bricks.

MSDS
MSDS
A safety data sheet (SDS), material safety data sheet (MSDS), or product safety data sheet (PSDS) is an important component of product stewardship, occupational safety and health, and spill-handling procedures. SDS formats can vary from source to source within a country depending on national requirements.
SDSs are a widely used system for cataloging information on chemicals, chemical compounds, and chemical mixtures. SDS information may include instructions for the safe use and potential hazards associated with a particular material or product. The SDS should be available for reference in the area where the chemicals are being stored or in use.
Our team is in dedicate and professional position to provide above information for our customers and related operators to properly deal with what we supply to all over the world. You are welcome to contact us to get such information or data, and please click MSDS or just address support@unitshine.com.
