Question from a technopositivist perspective: is there anything that's almost-but-not-exactly asbestos (e.g. asbestos reacted to complex with some other molecule) that retains its advantages without the disadvantages?

I get that one main reason we used asbestos was that it was cheap to produce (it's in the ground, it's plentiful) — but it also has some rather unique applications that are very hard to replicate (e.g. fire blankets.)

Is there yet a "synthetic asbestos" or "treated asbestos" that captures these benefits, without the drawbacks involved in asbestos production+remediation? Or are the benefits of asbestos inherently linked to its drawbacks, through e.g. its fine-scale shape, similar to carbon nanotubes?
