Altech Chemicals Limited (Altech/the Company) is aiming to become one of the world's leading producers of 99.99% (4N) high purity alumina (HPA) (Al2O3) through the construction and operation of a 4,000tpa HPA plant at Tanjung Langsat Industrial Complex, Johor, Malaysia. Feedstock for the HPA plant will be sourced from the Company’s 100%-owned kaolin deposit at Meckering, Western Australia. HPA is a high-value, high margin and highly demanded product as it is the critical ingredient required for the production of synthetic sapphire. Synthetic sapphire is used in the manufacture of substrates for LEDs; semiconductor wafers used in the electronics industry; and scratch-resistant sapphire glass used for wristwatch faces, optical windows and smartphone components. An emerging use for HPA is as a coating for lithium-ion battery separators. There is no substitute for HPA in the manufacture of synthetic sapphire.
