1.95% alumina, heat compression molding or dry-pressed molding.
2.The chemical stability is better, abrasion resistant and corrosion stability.
3.The ceramic body is compact, and the mechanical strength is high.
4.Heat transfer is fast, and heat output is less,and good for thermal shock performance.
5.Plane fine polishing & Globoid fine polishing, the corners are not sharp.
6.Length tolerance ≤ ± 0.05mm, width tolerance ≤ ± 0.1mm, high tolerance ≤ ± 0.1mm, Parallelism ≤ 0.03mm.
7.Good flatness, no deformation.
8.The plate surface without pores,without miscellaneous points,without scratches and cracks.
9.The color of plate have white,cream,black,dark red,yellow and pink,the color uniformity is better, and have not chromatic aberration.
10.The products can be selected a formula that have negative ion.
