Vacuum Welding of Olivine Science

Welding of olivine was demonstrated by grinding it in a ball mill in an atmosphere of about 2 x 10-7 torr. Most of the sample adhered strongly to the container and grinding balls although adhesion in air is only slight. Similar adhesion should be expected on the lunar surface and may account for the roughness needed to explain the optical properties of the moon and the detail of the una 9 ...
