A New Route to Synthesis of Titanium Silicalite-1 by Ball

Titanium Silicalite-1 (TS-1) was successfully synthesized from amorphous silica and titania powders by using a ball-milling method. In this method, amorphous fumed silica and anatase titania powders were ground in a planetary ball mill to produce a silica-titania precursor. The obtained precursor was then hydrothermally treated where TPABr was used as a template to

Beryllium Copper an overview ScienceDirect Topics

Beryllium is used as an alloying agent in the production of beryllium–copper, which contains up to 2.5% beryllium. Beryllium–copper alloys are used in many applications because of their combination of high electrical and thermal conductivity, high strength and hardness, nonmagnetic properties, along with good corrosion and fatigue resistance.
