الوصف

CALCINED ALUMINA
CAS NO.: ********1
MF:AL2O3
Al2O3 Calcined alumina feature
(1) High melting point abd excellent mechanical strengh

(2) High strengh and stiffness

(3) Featured with small tempreature difference and long socking time

(4) High crystal phase transition rate and good batch stability

(5) It is easy to mill, and the milling time can be reduced by *0%**5%

(6) Excellent dielectric properties (from DC to GHZ frequencies)

Alpha-alumina

The high-performance alpha alumina series(including the powder and fine powder) are mainly in tunnel kiln calcine, using unique production process,relying on strong technical development strength.the products with stable quality,and perfect after-sale technical service, can meet different requirements of customers.

1): Activated alpha-alumina low sodium microcrystalline

	Chemical components %				α-Al₂O_{3 %}	Effecive density g/cm³	Particle sizeμm
	Al₂O₃	Na₂O	SiO₂	Fe₂O₃	α-Al₂O_{3 %}	Effecive density g/cm³	Particle sizeμm
A-LN**5	≥*9.0	≤0.*6	≤0.2	≤0.1	≥*5	≥3.*3	0.**1.0
A-LN**0	≥*9.0	≤0.*6	≤0.2	≤0.1	≥*5	≥3.*3	1.**1.5

Note: the particle size is processed as customers requirement

Main properties:
Grain size smaller, Higher sintering activity
Sodium Oxide content is very low
Fine powder grinding, the partical size narrow well distributed
used for refractory castable, lower water needing
used in porcelain ball and wear-resistant parts, low sintering temperature, heavy sintering
density

Main Usage
Fine procelain ball and raw material of wear-resistant parts
Chemical filling materials, raw material of alumina balll
Fine powder of refractory castable
