Product Description
Alumina ceramic parts are widely used in electrical appliances, petrochemical, machinery, textiles, automobiles and other industries. Alumina ceramics are currently divided into two types: high purity type and ordinary type. When the content of alumina ceramics is below 99%, it appears pure white. When the content reaches 99% and above, the color of the ceramic is typically light yellow.
